I’m having the same issue. It started after upgrading to iOS 27. I’ve even updated to 27.2 thinking it was a bug and fixed in the latest update/patch and it still happens. When I send text messages to other iPhone users, about half the time it sends as an SMS. It’s annoying for the recipients because they get two or more of the same text message. I’ve restarted my iPhone several times and nothing seems to work.

my imessage is not working at all with ios 27. imessage is turned on. my sms only sends and secives certain messages, blocks certain people, and will not let me respond to certain group chats. I have been to my service provider and swapped esims to see if that worked; it didn’t. They said to contact Apple but I thought I’d try this first

I’ve already looked through all of the directions on all of the topics and nothing has helped or been on topic
