When your iPhone shows “Sent as Text Message,” it sends your message as an SMS text message instead of an iMessage. This usually happens when iMessage becomes unavailable or when your mobile carrier handles the message. By understanding this notification, you can quickly identify why your iPhone used a different delivery method.
Many iPhone users assume that a green text message means someone blocked them or that their device has a problem. In most cases, neither is true. This guide reveals the real reasons your iPhone switches from iMessage to SMS and explains what those changes mean for your messages.
In this guide, you’ll learn how SMS, iMessage, green message bubbles, and delivery status work. You’ll also discover the truth behind common blocked myths, troubleshoot messaging issues, and find practical ways to stop your iPhone from sending messages as SMS when you want to use iMessage.
What Does “Sent as Text Message” Mean on iPhone?
When you see “Sent as Text Message” under a message on your iPhone, your iPhone has sent the message as a regular SMS text message instead of an iMessage.
Normally, iPhones use iMessage when both people use Apple devices and have an internet connection. However, if iMessage becomes unavailable for any reason, your iPhone automatically switches to SMS and shows the “Sent as Text Message” notification.
In simple terms:
- Blue bubble = iMessage
- Green bubble = SMS text message
- “Sent as Text Message” = Your iPhone used SMS instead of iMessage
This feature helps ensure your message still reaches the other person even when iMessage is unavailable.
Quick Example
Imagine you send a message to your friend using iMessage.
- Your friend’s internet connection suddenly drops.
- iMessage cannot deliver the message.
- Your iPhone automatically switches to SMS.
- The message is sent through your mobile carrier.
- You see the notification “Sent as Text Message.”
This is called SMS fallback, and it helps prevent messages from getting stuck.
Common Reasons You See “Sent as Text Message”
Your iPhone may send a text message instead of iMessage when:
- The recipient is using an Android phone.
- The recipient turned off iMessage.
- You do not have an internet connection.
- The recipient does not have an internet connection.
- Apple’s iMessage servers are temporarily unavailable.
- The recipient recently switched devices.
- The recipient’s phone is powered off.
What Happens When an iPhone Sends a Text Message Instead of iMessage?
When your iPhone sends a text message instead of iMessage, the message travels through your mobile carrier’s network rather than Apple’s messaging servers.
This changes how the message is sent and delivered.
Here is what typically happens:
| iMessage | SMS Text Message |
| Uses internet connection | Uses cellular network |
| Blue message bubble | Green message bubble |
| Supports read receipts | Usually no read receipts |
| Supports typing indicators | No typing indicators |
| Works between Apple devices | Works on almost all phones |
Example
Let’s say you send:
“Are we meeting at 6 PM?”
If iMessage is available:
- The bubble appears blue.
- You may see “Delivered.”
- You may see “Read” if enabled.
If iMessage is unavailable:
- The bubble appears green.
- The message is sent through SMS.
- You may not see delivery or read information.
What Does SMS Fallback Do?
SMS fallback is a built-in iPhone feature that automatically switches from iMessage to SMS when necessary.
Benefits include:
- Prevents failed messages.
- Helps urgent messages go through.
- Allows communication with Android users.
- Reduces message delivery issues.
Helpful Tip
If your messages frequently switch to SMS, check:
- Wi-Fi connection
- Cellular data connection
- iMessage settings
- Apple System Status
- Carrier signal strength
Doing this can help restore normal iMessage functionality.
Does “Sent as Text Message” Mean the Message Was Delivered?
Not always.
One of the biggest misconceptions is that “Sent as Text Message” automatically means the recipient received the message.
In reality, it only confirms that your iPhone successfully sent the message as SMS through your carrier.
Whether the recipient actually receives it depends on several factors.
What It Usually Means
When you see:
Sent as Text Message
Your iPhone is telling you:
- The message left your device.
- SMS was used instead of iMessage.
- Your carrier accepted the message for delivery.
What It Does NOT Guarantee
The notification does not confirm that:
- The recipient read the message.
- The recipient’s phone is turned on.
- The recipient has cellular service.
- The recipient actually received the message.
Example
Suppose your friend’s phone battery is dead.
You send a text.
Your iPhone shows:
Sent as Text Message
The message has been sent from your side, but your friend cannot receive it until their phone turns back on.
Can You Tell If the Message Was Delivered?
With SMS, delivery confirmation is limited.
Unlike Apple Messages, standard SMS often does not show:
- Delivered status
- Read receipts
- Typing indicators
Because of this, there is no guaranteed way to know whether an SMS was received unless the recipient replies.
Quick Answer
Does “Sent as Text Message” mean delivered?
Not necessarily.
It means your iPhone successfully sent the message as SMS, but it does not confirm that the recipient received or read it.
iMessage vs SMS: What Is the Difference?
Understanding the difference between iMessage, SMS messaging, and RCS messaging can help explain why your iPhone sometimes displays “Sent as Text Message.”
Although all three allow people to send messages, they work differently and offer different features.
At a Glance Comparison
| Feature | iMessage | SMS | RCS |
| Uses Internet | Yes | No | Yes |
| Uses Mobile Carrier | No | Yes | Partially |
| Read Receipts | Yes | Usually No | Yes |
| Typing Indicators | Yes | No | Yes |
| Photo & Video Quality | High | Lower | High |
| Works With Android | No | Yes | Yes |
| Message Bubble on iPhone | Blue | Green | Green |
How iMessage Works on iPhone
iMessage is Apple’s internet-based messaging service built into the Messages app.
It works when:
- Both users have Apple devices.
- iMessage is enabled.
- An internet connection is available.
When these conditions are met, messages are sent through Apple’s servers rather than through your cellular carrier.
Features of iMessage
- Blue message bubbles
- Read receipts
- Typing indicators
- End-to-end encryption
- High-quality media sharing
- Message reactions and effects
- Message editing and unsending
Example
If you send a message from one iPhone to another iPhone while both devices are online, the message will usually be delivered as an iMessage.
You will see a blue bubble instead of a green one.
How SMS Text Messages Work
SMS (Short Message Service) is the traditional text messaging system used by mobile carriers.
Unlike iMessage, SMS does not require internet access.
Instead, messages travel through your carrier’s cellular network.
Features of SMS
- Works on almost every phone.
- Does not require Wi-Fi.
- Uses your carrier’s texting service.
- Usually appears as green bubbles on iPhone.
- Limited messaging features.
Example
If you send a message from an iPhone to an Android device, the message is often sent as SMS unless RCS support is available.
When SMS Is Used
Your iPhone may use SMS when:
- iMessage is unavailable.
- Internet access is unavailable.
- You are texting a non-Apple device.
- Send as SMS is enabled in settings.
SMS vs iMessage vs RCS Messaging
Many users now hear about RCS messaging and wonder how it compares to SMS and iMessage.
RCS (Rich Communication Services) is considered the modern replacement for SMS.
It offers many advanced features similar to iMessage.
What Is RCS?
RCS is a messaging standard that supports:
- Read receipts
- Typing indicators
- High-quality media sharing
- Group chats
- Better message delivery information
Which Messaging System Is Best?
Generally:
- iMessage (Best for Apple users)
- RCS (Best for cross-platform messaging)
- SMS (Most basic but universally supported)
Quick Summary
- iMessage uses the internet and appears in blue bubbles.
- SMS uses your carrier network and appears in green bubbles.
- RCS is an upgraded messaging system with modern chat features.
- When iMessage cannot be used, your iPhone may display “Sent as Text Message” and send the message using SMS instead.
Why Does My iPhone Say “Sent as Text Message”?
If your iPhone displays “Sent as Text Message”, it means the message was sent as an SMS text message instead of an iMessage.
This usually happens when iMessage cannot be used at that moment. Rather than letting your message fail, the iPhone automatically switches to SMS so your message still has a chance to reach the recipient.
Many users immediately think they have been blocked when they see this notification. In most cases, that is not true.
The message can switch from iMessage to SMS for several normal reasons, including internet issues, device settings, carrier problems, or messaging someone who does not use an Apple device.
Quick Answer
If your iPhone says “Sent as Text Message,” it usually means:
- iMessage was unavailable.
- SMS fallback was activated.
- The message was sent through your carrier.
- The recipient may not be using an Apple device.
- An internet connection was unavailable on either side.
Let’s look at the most common reasons in detail.
You Sent a Message to a Non-Apple Device
One of the most common reasons for seeing “Sent as Text Message” is that you are messaging someone who does not use an Apple device.
Since iMessage only works between Apple devices, your iPhone must use SMS when texting phones from other brands.
Example
Suppose:
- You have an iPhone.
- Your friend has a Samsung Galaxy phone.
When you send a message:
- The bubble appears green.
- The message is sent as SMS or RCS.
- You may see “Sent as Text Message.”
This is completely normal and does not indicate any problem.
Signs This Is the Cause
- The recipient uses Android.
- Messages are always green.
- You never see blue bubbles in that conversation.
The Recipient Is Using Android Instead of iPhone
Many users search for:
“What does sent as SMS mean iPhone to Android?”
The answer is simple.
When an iPhone communicates with an Android device, Apple cannot use its iMessage service because Android phones do not support iMessage.
Instead, your iPhone sends messages through:
- SMS
- MMS
- RCS (on supported devices and carriers)
Example
iPhone → iPhone = Usually iMessage
iPhone → Android = Usually SMS, MMS, or RCS
Because of this, seeing “Sent as Text Message” while messaging Android users is expected behavior.
Helpful Tip
If every message to a specific contact is green, verify whether they recently switched from iPhone to Android.
This often explains why conversations suddenly stop using iMessage.
iMessage Is Temporarily Unavailable
Sometimes Apple’s messaging service experiences temporary issues.
When this happens, your iPhone may automatically switch to SMS to keep your conversations moving.
Common Causes
- Apple server outages
- Temporary software glitches
- Network congestion
- iMessage activation issues
Example
You send a message.
Instead of displaying:
Delivered
Your iPhone displays:
Sent as Text Message
In this situation, the problem may be with iMessage itself rather than with your phone or the recipient.
Quick Tip
If multiple contacts suddenly start receiving SMS messages instead of iMessages, check whether Apple’s messaging services are experiencing issues.
No Internet Connection on Your Device
iMessage requires an internet connection.
Without Wi-Fi or mobile data, iMessage cannot function properly.
If SMS fallback is enabled, your iPhone may send the message through your carrier instead.
Common Situations
- Airplane mode enabled
- Weak Wi-Fi signal
- Mobile data turned off
- Poor network coverage
Example
You are traveling through an area with no internet access.
You send a message.
Your iPhone cannot connect to Apple’s servers, so it sends the message as SMS.
The result:
Sent as Text Message
How to Check
Before assuming anything is wrong:
- Verify Wi-Fi is connected.
- Check mobile data is enabled.
- Open a website to test internet access.
The Recipient Has No Internet Connection
Even if your internet works perfectly, the recipient may not have an active connection.
Because iMessage requires both devices to be online, the recipient’s connectivity issues can trigger SMS fallback.
Example
Your friend is:
- On a flight
- In an area with poor reception
- Connected to a broken Wi-Fi network
Your iPhone may switch to SMS to improve delivery chances.
Important Fact
This situation is common and does not mean the recipient blocked you.
The Recipient Turned Off iMessage
Some users disable iMessage intentionally.
When this happens, Apple can no longer deliver messages through iMessage.
Your iPhone automatically switches to SMS instead.
Example
The recipient:
- Opens Settings.
- Disables iMessage.
- Continues using regular text messaging.
When you send a message:
- The bubble becomes green.
- The notification may say “Sent as Text Message.”
Signs This May Be the Reason
- Messages suddenly switched from blue to green.
- The recipient still uses an iPhone.
- Other Apple features continue working normally.
The Recipient Switched to a New Phone
Changing devices can temporarily affect iMessage registration.
This often happens when someone:
- Buys a new iPhone.
- Switches to Android.
- Changes their phone number.
- Restores a device from backup.
Example
Your friend recently upgraded phones.
During setup, iMessage may not activate immediately.
While activation is pending, your messages may be sent as SMS.
Helpful Tip
If the change happened recently, wait a few hours and try again later.
Many activation issues resolve automatically.
The Recipient’s Device Is Powered Off
A powered-off device cannot connect to Apple’s messaging servers.
In some cases, your iPhone may send the message through SMS instead.
Example
Your friend’s battery dies.
You send a message.
Instead of waiting indefinitely for iMessage delivery, your phone uses SMS fallback.
The notification may show:
Sent as Text Message
Important Note
A powered-off phone is very different from being blocked.
Many users confuse these situations, but both can produce similar messaging behavior.
Why Is My iMessage Green and Says “Sent as Text Message”?
Many iPhone users become concerned when their blue iMessages suddenly turn green and display “Sent as Text Message.”
The good news is that this is usually caused by a normal messaging condition rather than a serious problem.
Understanding what green messages mean can help you determine whether the issue is related to iMessage, internet connectivity, Android devices, or account settings.
What Does a Green Text Message Mean on iPhone?
On iPhone, message color tells you how the message was sent.
Blue Message Bubble
A blue bubble means:
- The message was sent through iMessage.
- An internet connection was used.
- Apple messaging features are available.
Green Message Bubble
A green bubble means:
- The message was sent through SMS or MMS.
- Your cellular carrier handled the message.
- iMessage was not used.
Quick Color Guide
| Message Color | Meaning |
| Blue | iMessage |
| Green | SMS or MMS |
Example
If you text another iPhone user with working internet, you usually see a blue bubble.
If you text an Android user, you usually see a green bubble.
What Does a Green “Sent as Text Message” Notification Mean?
When a green bubble appears alongside “Sent as Text Message,” your iPhone is confirming that SMS delivery was used instead of iMessage.
This generally means:
- iMessage could not be used.
- SMS fallback was successful.
- The message was routed through your carrier.
Common Reasons
- No internet connection
- Android recipient
- iMessage disabled
- Apple server issue
- Device activation problem
Example
You send:
“Call me when you’re free.”
Normally:
- Blue bubble
- Sent via iMessage
After losing internet:
- Green bubble
- Sent as Text Message
The content remains the same. Only the delivery method changes.
Important Clarification
A green message does not automatically mean:
- You are blocked.
- The recipient ignored you.
- The message failed.
It simply means SMS was used.
Blue vs Green Message Bubbles Explained
One of the easiest ways to understand iPhone messaging is to learn the difference between blue and green bubbles.
Blue Bubbles
Blue bubbles indicate:
- Apple Messages
- iMessage service
- Internet-based delivery
- Read receipts
- Typing indicators
- End-to-end encryption
Green Bubbles
Green bubbles indicate:
- SMS messaging
- MMS messaging
- Carrier-based delivery
- Limited messaging features
Side-by-Side Comparison
| Feature | Blue Bubble (iMessage) | Green Bubble (SMS) |
| Internet Required | Yes | No |
| Read Receipts | Yes | Usually No |
| Typing Indicators | Yes | No |
| Encryption | Yes | Limited |
| Apple-to-Apple Messaging | Yes | No |
| Works With Android | No | Yes |
When Should You Be Concerned?
Occasional green messages are normal.
However, you may want to investigate if:
- All contacts suddenly become green.
- iMessage was working earlier but stopped.
- Messages fail repeatedly.
- You recently changed devices.
Quick Troubleshooting Checklist
If messages unexpectedly turn green:
- Confirm iMessage is enabled.
- Restart your iPhone.
- Check Wi-Fi and mobile data.
- Update iOS.
- Verify your Apple ID is active.
- Make sure the recipient still uses iMessage.
Key Takeaway
A green message bubble combined with “Sent as Text Message” usually means your iPhone used SMS because iMessage was unavailable. In most cases, this is caused by internet, device, or compatibility issues—not because you have been blocked.
Does “Sent as Text Message” Mean I Am Blocked?
One of the most common questions iPhone users ask is:
“Does Sent as Text Message mean blocked?”
The short answer is no.
Seeing “Sent as Text Message” does not automatically mean someone has blocked your phone number. In most cases, the message was simply sent through SMS messaging instead of iMessage because iMessage was unavailable.
Many normal situations can cause this notification, including:
- Poor internet connection
- iMessage being turned off
- Apple server issues
- The recipient using Android
- The recipient’s phone being powered off
- A temporary network problem
Because so many factors can cause SMS fallback, the notification alone cannot prove that you have been blocked.
Quick Answer
If you see:
Sent as Text Message
It usually means:
- Your iPhone used SMS instead of iMessage.
- The message was sent through your carrier.
- iMessage was unavailable at that moment.
It does not automatically mean you are blocked.
Does Sent as Text Message Mean Blocked on iPhone?
No.
A text message being sent as SMS is not considered a reliable sign of blocking on an iPhone.
Many users notice that a conversation suddenly changes from blue bubbles to green bubbles and immediately assume they were blocked. However, that is usually not the case.
Example
Imagine your friend:
- Loses internet access.
- Turns off iMessage.
- Switches to Android.
In all three situations:
- Your blue iMessages may become green.
- You may see “Sent as Text Message.”
- You may think you are blocked.
However, none of these situations involve blocking.
Common Reasons Besides Blocking
The message may switch to SMS because:
- The recipient has no internet connection.
- Apple’s servers are unavailable.
- The recipient disabled iMessage.
- The recipient changed phones.
- Your internet connection is unstable.
Because these situations are common, Apple does not use the “Sent as Text Message” notification as a blocking indicator.
If iPhone Says “Sent as Text Message,” Am I Blocked?
Usually, no.
A single SMS notification does not provide enough information to determine whether someone blocked you.
Many people search:
“If iPhone says sent as text message am I blocked?”
The answer is that there is no direct way to know from this notification alone.
Example
Let’s compare two situations.
Scenario 1: Not Blocked
Your friend:
- Is traveling.
- Has no internet access.
- Receives SMS only.
Result:
- Message sends as SMS.
- Green bubble appears.
- You see “Sent as Text Message.”
Scenario 2: Potential Block
Someone blocks your number.
Result:
- Message behavior may look similar.
- Green bubbles may appear.
- SMS may still be sent.
Because both situations can look alike, the notification itself is not enough evidence.
Helpful Tip
Avoid assuming you are blocked based on one message.
Look for multiple signs before drawing conclusions.
What Are the Real Signs That Someone Blocked You?
Apple does not provide a direct “You have been blocked” notification.
However, there are several indicators that may suggest blocking.
Possible Signs of Being Blocked
Messages Never Show Delivered
If your iMessages previously displayed:
Delivered
But now never show delivery confirmation, it may be a sign.
However, it can also happen because:
- The phone is off.
- The recipient has no internet.
- iMessage is disabled.
Calls Go Straight to Voicemail
If every call immediately goes to voicemail without ringing, this may be another indicator.
Again, this is not proof because:
- Do Not Disturb may be enabled.
- The phone could be off.
- The recipient may have poor signal.
Multiple Communication Methods Stop Working
If:
- Messages stop getting responses.
- Calls never connect.
- FaceTime no longer works.
There may be a greater chance that blocking occurred.
Important Reminder
No single sign can confirm a block.
A combination of several indicators is usually needed.
Why a Text Message Alone Cannot Confirm a Block
The biggest mistake users make is assuming that SMS delivery equals blocking.
In reality, SMS is simply a backup messaging method.
Why SMS Is Not Proof
The same SMS notification can appear when:
- Internet service fails.
- iMessage servers are down.
- Android devices are involved.
- A phone is turned off.
- iMessage is disabled.
Example
Suppose two people experience identical messaging behavior:
Person A was blocked.
Person B lost internet access.
Both conversations may show:
- Green bubbles
- SMS messages
- No delivery confirmation
Because the visible results are similar, there is no way to know for sure based solely on the text message notification.
Key Takeaway
“Sent as Text Message” is not a reliable blocking indicator.
It simply means the message was sent through SMS instead of iMessage.
What Does “Sent as SMS” Mean on iPhone?
When your iPhone displays “Sent as SMS”, it means your message was sent through your mobile carrier’s Short Message Service (SMS) instead of Apple’s iMessage service.
This typically happens when iMessage cannot be used.
Rather than letting the message fail, the iPhone automatically switches to SMS if the Send as SMS option is enabled.
Quick Answer
“Sent as SMS” means:
- The message used SMS delivery.
- The message did not use iMessage.
- Your cellular carrier handled the message.
- Internet-based messaging was unavailable.
What Does Send as SMS Mean on iPhone?
Send as SMS is an iPhone feature that allows messages to be delivered through your carrier when iMessage cannot send them.
This feature helps ensure that important messages still go through.
Example
You send a message while your internet connection drops.
Instead of failing completely:
- iMessage stops working.
- SMS fallback activates.
- The message is delivered through your carrier.
The result:
Sent as SMS
Benefits of Send as SMS
- Prevents failed messages.
- Improves message delivery.
- Works without Wi-Fi.
- Supports communication with non-Apple devices.
What Does Sent as SMS Text Mean on iPhone?
The phrase “Sent as SMS” and “Sent as Text Message” generally mean the same thing.
Both indicate that:
- SMS delivery was used.
- iMessage was not available.
- The message traveled through a carrier network.
Example
You may see:
Sent as SMS
or
Sent as Text Message
Both notifications refer to SMS delivery rather than iMessage delivery.
Why Does It Say “Text Message • SMS” on iPhone?
Many users notice the label:
Text Message • SMS
inside the Messages app.
This label helps identify the type of messaging service being used.
What It Means
The conversation is currently using:
- SMS
- MMS
- Carrier-based messaging
Instead of:
- iMessage
Common Reasons
You may see this label when:
- Messaging Android users.
- iMessage is disabled.
- Internet access is unavailable.
- Apple services are temporarily unavailable.
Helpful Tip
If you want blue iMessages instead of SMS messages:
- Enable iMessage.
- Connect to Wi-Fi or mobile data.
- Confirm the recipient also uses iMessage.
What Does “Sent as SMS” Mean When Messaging Android Users?
Many iPhone users become confused when messaging Android users because conversations often behave differently from iPhone-to-iPhone chats.
In most cases, this is completely normal.
Sent as SMS From iPhone to Android Explained
Apple’s iMessage service only works between Apple devices.
When you send a message from an iPhone to an Android phone, the message usually uses:
- SMS
- MMS
- RCS (when supported)
Example
iPhone → iPhone
Result:
- Blue bubble
- iMessage
iPhone → Android
Result:
- Green bubble
- SMS, MMS, or RCS
This is expected behavior.
Does Sent as SMS Mean Blocked From iPhone to Android?
No.
Messaging Android users through SMS does not indicate blocking.
Why This Happens
Since Android devices do not support iMessage, your iPhone automatically uses another messaging method.
The notification simply reflects the delivery method.
Example
You send a message to a Samsung phone.
Your iPhone displays:
Sent as SMS
This only means SMS delivery was used.
It does not suggest blocking.
What Does Sent as SMS Mean on Android?
On Android devices, Sent as SMS generally means the message was delivered using standard carrier text messaging rather than internet-based messaging services.
Common Android Messaging Methods
- SMS
- MMS
- RCS Chat
Example
If RCS chat features become unavailable, many Android phones automatically fall back to SMS.
The user may then see a message indicating SMS delivery.
Does Sent as SMS Mean Blocked on Android?
No.
Just like on iPhone, SMS delivery on Android does not automatically mean someone blocked you.
Common Reasons Android Uses SMS
- RCS is disabled.
- Internet connectivity problems.
- Carrier issues.
- The recipient’s device does not support RCS.
Quick Answer
If Android says:
Sent as SMS
It usually means:
- The message was sent through a carrier network.
- Internet-based messaging was unavailable.
- SMS fallback was activated.
It does not automatically indicate blocking.
Key Takeaway
Whether you use an iPhone or Android device, “Sent as SMS” simply describes how the message was delivered. It is a messaging method, not a blocking notification. In most situations, it means your phone switched from an internet-based messaging service to standard SMS to ensure the message could still be sent.
How to Control SMS and iMessage Settings on iPhone
If your iPhone keeps showing “Sent as Text Message”, understanding your messaging settings can help you control when messages are sent as iMessage and when they are sent as SMS.
Many messaging problems are caused by settings that were accidentally changed, internet issues, or temporary software glitches. Fortunately, most of these problems can be fixed in just a few minutes.
This section explains how to manage your iPhone Messages settings, enable or disable SMS fallback, and troubleshoot common iMessage issues.
Quick Overview
The most important settings are:
- iMessage
- Send as SMS
- Cellular Data
- Wi-Fi Connection
- Apple ID for Messages
If any of these settings are disabled or not working properly, your messages may switch from iMessage to SMS.
How to Turn Send as SMS On or Off
The Send as SMS feature allows your iPhone to automatically send messages as SMS when iMessage cannot be delivered.
This is known as SMS fallback.
What Happens When Send as SMS Is Enabled?
If iMessage fails:
- Your iPhone automatically switches to SMS.
- The message is sent through your mobile carrier.
- You may see “Sent as Text Message.”
This helps ensure important messages are still delivered.
How to Enable or Disable Send as SMS
Follow these steps:
- Open Settings.
- Tap Apps (on newer iOS versions) or go directly to Messages.
- Select Messages.
- Find Send as SMS.
- Turn the toggle On or Off.
When Should You Keep It Enabled?
Most users should keep it enabled because:
- Messages are less likely to fail.
- Emergency messages can still be delivered.
- Conversations continue even if iMessage has issues.
When Might You Turn It Off?
Some users disable it because:
- They only want to use iMessage.
- They want to avoid SMS charges.
- They prefer messages to wait for internet delivery.
Helpful Tip
If you frequently communicate with Android users, keeping Send as SMS enabled is usually the best option.
How to Check Whether iMessage Is Enabled
If iMessage is disabled, your iPhone cannot send or receive iMessages.
Instead, messages may be sent as SMS whenever possible.
How to Check iMessage Status
- Open Settings.
- Tap Messages.
- Look for iMessage.

- Wait one minute.
- Turn iMessage back on.
Fix 4: Update iOS
Outdated software can sometimes interfere with messaging services.
To check:
- Open Settings.
- Tap General.
- Select Software Update.
Fix 5: Verify the Recipient Can Use iMessage
Even if your settings are correct, the recipient may:
- Use Android.
- Have iMessage disabled.
- Have internet issues.
In these situations, SMS may be the only available option.
Quick Troubleshooting Checklist
If messages keep sending as SMS:
- ✅ Check Wi-Fi
- ✅ Check cellular data
- ✅ Verify iMessage is enabled
- ✅ Restart the iPhone
- ✅ Update iOS
- ✅ Verify the recipient uses iMessage
- ✅ Confirm Apple servers are operating normally
Common Problems Related to “Sent as Text Message”
Most people search for “Sent as Text Message” because something unusual happened inside the Messages app.
For example:
- Blue bubbles suddenly turn green.
- iMessages stop sending.
- Messages always use SMS.
- Messages get stuck while sending.
Understanding the cause can help you solve the problem much faster.
Messages Suddenly Turning Green
One of the most common complaints is:
“Why did my iMessages suddenly turn green?”
A green bubble simply means the message was sent using SMS or MMS instead of iMessage.
Common Reasons Messages Turn Green
- No internet connection
- iMessage disabled
- Recipient uses Android
- Apple server outage
- Phone number registration issue
Example
Yesterday:
- Messages were blue.
Today:
- Messages are green.
Possible explanation:
Your friend switched from iPhone to Android.
What to Check First
Before assuming a serious issue:
- Verify internet access.
- Confirm iMessage is enabled.
- Ask whether the recipient changed devices.
Helpful Tip
A green bubble alone does not mean you have been blocked.
It only indicates a different delivery method.
iMessages Not Sending
Sometimes messages fail completely and never leave the device.
This can happen when iMessage cannot connect to Apple’s servers.
Common Causes
- Weak internet connection
- Apple ID issue
- Software bugs
- Incorrect date and time settings
- Carrier network issues
Signs of the Problem
You may see:
- Red exclamation marks
- Sending errors
- Endless loading indicators
- Messages stuck in progress
What to Do
Try these steps:

Messages Sending as SMS Every Time
If every message is being sent as SMS, there is usually a settings or activation issue.
Possible Causes
- iMessage is turned off.
- iMessage activation failed.
- The recipient does not use iMessage.
- Apple ID configuration issues.
- Cellular carrier restrictions.
Example
If all conversations suddenly become green, investigate:
- iMessage settings
- Apple ID status
- Network connectivity
Quick Fixes
Try:
- Re-enabling iMessage
- Restarting the phone
- Updating iOS
- Checking Apple ID settings
iPhone Messages Stuck on Sending
Sometimes a message never completes delivery and remains stuck on the sending screen.
This can happen with both SMS and iMessage.
Common Causes
- Weak signal
- Network interruptions
- Carrier issues
- Software glitches
- Large media attachments
Example
You send:
“See you at 7.”
The message shows a spinning progress bar for several minutes.
This often indicates a connection issue rather than a problem with the recipient.
How to Fix Stuck Messages
Try the following:
- Toggle Airplane Mode on and off.
- Connect to a stronger Wi-Fi network.
- Restart your device.
- Delete and resend the message.
- Update iOS.
- Reset network settings if necessary.
Expert Tip
If text-only messages send successfully but photos and videos get stuck, the problem may be related to MMS messaging, file size limits, or network speed rather than iMessage itself.
Quick Problem-Solving Summary
| Problem | Most Likely Cause |
| Messages turned green | SMS used instead of iMessage |
| iMessages not sending | Internet or iMessage issue |
| Messages always sent as SMS | iMessage disabled or unavailable |
| Messages stuck on sending | Connectivity or network problem |
| “Sent as Text Message” appears | SMS fallback activated |
Key Takeaway
Most “Sent as Text Message” issues are caused by internet connectivity, device settings, or compatibility differences between messaging systems. In the majority of cases, checking your iMessage settings, internet connection, and Apple ID configuration will resolve the problem without requiring advanced troubleshooting.
Frequently Asked Questions
Does Sent as Text Message Mean Blocked?
No, “Sent as Text Message” does not automatically mean you have been blocked.
This is one of the biggest misconceptions among iPhone users. In reality, this notification usually means your message was sent through SMS messaging instead of iMessage because iMessage was unavailable at that moment.
There are many reasons this can happen, including:
- The recipient is using Android.
- The recipient turned off iMessage.
- Your internet connection is weak.
- The recipient has no internet access.
- Apple’s iMessage service is temporarily unavailable.
- The recipient’s phone is powered off.
Example
Suppose you send a message to a friend who is traveling in an area with poor internet coverage.
Instead of sending as an iMessage, your iPhone switches to SMS and displays:
Sent as Text Message
In this situation, you are not blocked. The message was simply delivered using a different messaging method.
Important Tip
Do not use a single SMS notification as proof of blocking.
If someone blocks your number, there is usually no direct notification from Apple confirming it.
Quick Answer
Does Sent as Text Message mean blocked?
No. It usually means your iPhone used SMS instead of iMessage because internet-based messaging was unavailable.
Does Sent as Text Message Mean Delivered?
Not always.
When you see “Sent as Text Message,” it means your iPhone successfully sent the message through your cellular carrier. However, it does not guarantee that the recipient received or read the message.
What the Notification Confirms
The notification tells you:
- The message left your device.
- SMS delivery was used.
- Your carrier accepted the message.
What It Does Not Confirm
The notification does not tell you whether:
- The recipient received the message.
- The recipient opened the message.
- The recipient read the message.
- The recipient’s phone is turned on.
Example
Imagine your friend’s phone battery dies.
You send a text message.
Your iPhone displays:
Sent as Text Message
The message has been sent from your side, but your friend cannot receive it until their phone reconnects to the network.
Quick Answer
Does Sent as Text Message mean delivered?
Not necessarily. It confirms the message was sent as SMS, but it does not guarantee delivery or that the recipient has read it.
Why Are Some iPhone Messages Sent as Text Messages?
iPhone messages are sent as text messages whenever iMessage cannot be used.
Apple designed the Messages app to automatically switch to SMS when necessary so conversations can continue without interruption.
This feature is commonly called SMS fallback.
Common Reasons Messages Are Sent as Text Messages
- No Wi-Fi connection
- Mobile data is unavailable
- The recipient uses Android
- iMessage is disabled
- Apple server issues
- The recipient recently changed devices
- Temporary network problems
Example
Normally:
- You send an iMessage.
- The bubble is blue.
If internet connectivity is lost:
- Your iPhone switches to SMS.
- The bubble turns green.
- You may see “Sent as Text Message.”
Helpful Tip
If only one conversation uses SMS while others use iMessage, the issue is often related to the recipient’s device rather than your iPhone.
Quick Answer
Some iPhone messages are sent as text messages because iMessage is unavailable and the phone automatically falls back to SMS delivery.
Why Is My iMessage Green Instead of Blue?
On iPhone, the color of the message bubble indicates how the message was sent.
Blue Message Bubble
A blue bubble means:
- The message was sent using iMessage.
- An internet connection was used.
- Apple messaging features are available.
Green Message Bubble
A green bubble means:
- The message was sent using SMS or MMS.
- Your cellular carrier handled the message.
- iMessage was not used.
Common Reasons Messages Turn Green
- The recipient uses Android.
- iMessage is disabled.
- Internet connectivity issues.
- Apple server outages.
- iMessage activation problems.
Example
If you text another iPhone user with working internet, the bubble is usually blue.
If you text an Android user, the bubble is usually green.
Quick Color Guide
| Message Color | Meaning |
| Blue | iMessage |
| Green | SMS or MMS |
Helpful Tip
A green message bubble does not automatically mean there is a problem. In many cases, it simply means the conversation is using SMS instead of iMessage.
Quick Answer
Why is my iMessage green instead of blue?
Because the message was sent using SMS or MMS rather than Apple’s iMessage service.
What Does Send as Text Message Do on iPhone?
The Send as Text Message feature allows your iPhone to automatically send messages through SMS when iMessage is unavailable.
Without this feature, some messages might fail completely if iMessage cannot connect.
How It Works
When iMessage cannot send a message:
- The iPhone detects the issue.
- SMS fallback is activated.
- The message is sent through your carrier’s network.
- You may see “Sent as Text Message.”
Benefits of Send as Text Message
- Improves message delivery.
- Prevents failed messages.
- Works when internet access is unavailable.
- Helps messages reach Android users.
- Provides a backup communication method.
Example
You are connected to weak Wi-Fi and try to send an iMessage.
The iMessage fails.
Instead of canceling the message, your iPhone automatically sends it as SMS.
This allows the conversation to continue without interruption.
When Is It Most Useful?
The feature is especially helpful when:
- Traveling
- Experiencing poor internet connectivity
- Messaging Android users
- Dealing with temporary iMessage outages
Quick Answer
What does Send as Text Message do on iPhone?
It allows your iPhone to switch from iMessage to SMS when internet-based messaging is unavailable, helping ensure that your messages can still be sent.
Final Thought
Seeing “Sent as Text Message” on your iPhone does not usually mean there is a problem.

Understanding the difference between iMessage, SMS, and green text messages can help you avoid confusion and troubleshoot messaging issues more easily.
If your messages keep switching to SMS, checking your iPhone Messages settings, internet connection, and iMessage status can often solve the issue. With the tips in this guide, you can better understand message delivery, green bubbles, and why your iPhone displays “Sent as Text Message” in different situations.
