Facebook Messenger Messages Not Sending Fix is needed when your messages stay stuck on sending, show a failed message, or do not get delivered.
This issue can happen because of internet problems, Messenger app glitches, account session issues, blocked conversations, outdated app versions, corrupted cache, or temporary Meta service problems.
Quick Fix
Check your internet connection, close and reopen Messenger, then try sending the message again. If the message still stays stuck, update Messenger and clear the app cache.
Try This First
• Message stuck on sending → check internet connection
• Message failed to send → close and reopen Messenger
• Messages not delivered to one person → check if you are blocked or restricted
• Messenger works slowly → clear cache and update the app
If the issue continues, follow the fixes below.
Why Are Messenger Messages Not Sending?
Messenger messages may fail to send when the app cannot connect to Meta servers, refresh your account session, or deliver the message to the other person.
This can appear as messages stuck on sending, a spinning circle, failed delivery, delayed messages, or messages that only send after you reopen the app.
What Causes Messenger Messages Not Sending?
The most common causes include:
• Weak or unstable internet connection
• Messenger app glitches
• Outdated Messenger app
• Corrupted app cache
• Account login or session problems
• Background data restrictions
• Temporary Messenger service problems
• Conversation restrictions or blocked contact issues
This issue can come from your internet connection, Messenger app, Facebook account session, phone settings, or Messenger itself.
How to Fix Facebook Messenger Messages Not Sending
Follow these steps until Messenger sends messages normally again.
Check Your Internet Connection
- Open another app, such as YouTube, Facebook, or a browser
- Check if pages, videos, or posts load normally
- If other apps are slow, turn WiFi OFF and ON
- Try switching from WiFi to mobile data
- Open Messenger again
- Send a short test message
If Messenger itself is not working properly, follow this guide: Facebook Messenger Not Working Fix
Messenger needs a stable connection to send messages, update delivery status, and load conversations.
Close and Reopen Messenger
- Open your phone’s recent apps screen
- Find Messenger
- Swipe it away to close it completely
- Wait a few seconds
- Open Messenger again
- Try sending the message one more time
Closing and reopening Messenger refreshes the app and can fix temporary sending glitches.
Send a Short Test Message
- Open the same Messenger chat
- Type a short message, such as test
- Tap Send
- Wait a few seconds
- Check whether the short message sends
- If the short message sends, try sending your original message again
A short test message helps confirm whether the problem is the app connection or something specific in the message you were trying to send.
Check If the Message Has a Large Attachment
- Look at the message that is stuck
- Check if it includes a large photo, video, voice message, or file
- Remove the attachment if possible
- Try sending only text first
- If text sends, try sending the photo or video separately
- Use WiFi if the file is large
Large attachments need a stronger connection and may fail on weak WiFi or mobile data.
Update the Messenger App
- Open the Google Play Store on Android or the App Store on iPhone
- Tap the search bar
- Type Messenger
- Open the official Messenger app page
- Tap Update if an update is available
- Wait for the update to finish
- Restart your phone
- Open Messenger again
If you only see Open, Messenger is already updated.
Updating Messenger fixes bugs that may cause messages to fail, delay, or stay stuck on sending.
Clear Messenger Cache
- Open your phone Settings
- Tap Apps or Applications
- Find and tap Messenger
- Tap Storage
- Tap Clear Cache
- Open Messenger again
- Try sending the message
If Messenger keeps closing while you try to send messages, follow this guide: Facebook Messenger Keeps Crashing Fix
Clearing cache removes temporary Messenger files that may be corrupted. It does not delete your Facebook account or conversations.
Check Messenger Data Access
- Open your phone Settings
- Tap Apps or Applications
- Select Messenger
- Tap Mobile data, Data usage, or Network usage
- Make sure Messenger is allowed to use mobile data
- Turn Background data ON if the option appears
- Open Messenger again and test sending
If Messenger cannot use mobile data or background data, messages may stay stuck until the app reconnects.
Turn Off Battery Saver
- Open your phone Settings
- Tap Battery
- Look for Battery Saver, Power Saving Mode, or Low Power Mode
- Turn it OFF temporarily
- Open Messenger again
- Try sending the message
Battery saver can limit background activity and network access, which may delay Messenger messages.
Check If Facebook Login Is Working
- Open the Facebook app or Facebook in a browser
- Check if you are still logged in
- If Facebook asks you to log in again, enter your details carefully
- Complete any verification step if Facebook asks for one
- Open Messenger again
- Try sending a message
If you cannot access your Facebook account, follow this guide: Facebook Login Problem Fix
Messenger depends on your Facebook account session, so login problems can stop messages from sending.
Check If You Are Blocked or Restricted
- Try sending a message to another person
- If messages send to others but not one person, the issue may be with that conversation
- Check if the person’s profile is still visible
- Check if you can see previous messages normally
- Avoid sending repeated messages if delivery keeps failing
- Wait and try again later
If messages fail only with one person, the other person may have blocked you, restricted messages, deactivated their account, or changed privacy settings.
Check If Messenger Is Down
- Open a browser on your phone or computer
- Search for Messenger outage or Facebook Messenger server status
- Check if many users are reporting message problems
- Try Messenger on another device if possible
- Wait and try again later if Messenger is down
If Messenger is down for many users, the problem is not your phone and you need to wait until Meta fixes the service.
Restart Your Phone
- Save anything important you are doing
- Close Messenger and other open apps
- Press and hold the Power button
- Tap Restart or Reboot
- Wait for your phone to turn back on
- Open Messenger again
- Try sending the message
Restarting clears temporary phone problems that may affect Messenger, network access, or app performance.
Reinstall Messenger
- Press and hold the Messenger app icon
- Tap Uninstall or Remove App
- Confirm the removal
- Restart your phone
- Open the Google Play Store or App Store
- Search for Messenger
- Install Messenger again
- Open the app and sign in
- Try sending a message
Reinstalling Messenger removes damaged app files and gives the app a clean setup.

• Use a stable internet connection
