Fix Can’t Send Messages on iPhone 6s

Can’t send messages from iPhone 6s. Messages on iPhone 6s not sending. Error when sending a text message on iPhone 6s. Messages undelivered on iPhone. Messages won’t send or stuck on sending on iPhone 6s or iPhone 6s plus.


If you’re having issues with sending text messages or imessage from your iPhone 6s, then this is likely caused by a software issue and you should be able to fix it without too much trouble.

The first thing we’ll have to do is determine where the problem is with iMessage or with regular Text Messaging:

    • Go to Settings > Messages and Turn iMessage off.

    • Once iMessage is off, try sending a message.
    • If the message sends successfully, we know the issue is with iMessage. You will want to make sure you always have an internet connection when using iMessage. If you don’t have a data plan, it is preferable to keep iMessage off to avoid issues. If you do always have access to an internet connection through a data plan and use iMessage, perform the following steps:
      • Sign out of iMessage by going into Settings > Messages > Send & Receive, tapping your Apple ID, then tapping Sign Out.  
      • Power off your iPhone completely, then power it back on.
      • Go to Settings > Messages and tap Use your Apple ID for iMessage.
      • Test iMessage now by trying to send a message again. If you still can’t send a message successfully on your iPhone, follow the rest of the guide.
    • If the message doesn’t send successfully, the first thing to try is to Reset your network settings
      • Tap Settings > General > Reset > Reset Network Settings.  
  • Check the recipient’s contact info.
    • Make sure that you’re using the right phone number or email address. If necessary, delete the contact entirely from your phone, and re-add them as a new contact with the proper phone number (including the area code).
    • Go to Settings > Messages > Blocked and make sure that they’re not on your block list.
  • If you still can’t send a message to a certain number, then delete any existing conversations between you and that number, restart your iPhone and test again.
  • Check for updates by going into Settings > General > Software Updates and perform any software updates that might be available.  
  • If none of the above steps worked for you and fixed the issue, the last step is to perform a back up and restore of your device. For a guide on backing up and restoring your device, click here.

If everything else fails, contact your network service provider for further assistance and recommendations.
