How can I fix a "message failed to send" iMessage following 16.0 update

Since the 16.0 update, I am unable to successfully send a text message to a thread containing non-iPhone participants. I receive an error notification. How can I fix this?

iPhone 12 Pro

I deleted threads, restarted and tried again with no success.


Finally, successful after turning off vpn. I sent a few messages, received responses, turned vpn back on, and still successful. I think I'm good now.


Thanks for your suggestions!

Hi kneaa,


What specific error or message do you receive when trying to text non-iPhone contacts?


Also, are these existing threads or new threads? If you've only noticed this with existing threads, try creating a new message instead of responding in thread and see if the issue persists.


Let us know the error you receive and the results.


Cheers!

Hi- Thanks for responding. With regard to the error message: for each message I attempt, I receive "Not delivered" with a red circled exclamation point. In addition, I receive a general "Message Send Failure" error message.


I am able to message each of the participants individually.


I created a new message thread and continue to receive the error message.


I restarted several times.


Any suggestions are appreciated. Thanks!
