I have a iPhone 7 and 5s, both running the latest iOS 11.2.6. I tried the same SIM card in iPhone 7 and it’s failed and stuck at activating iMessage or FaceTime, tried to test in my 5s and everything works fine within seconds. I need apple to provide feedback ASAP as my daily job requires to use iMessage for business.
this is a user to user technical forum, there is no apple here.

I had a similar issue but a soft reset fixed the issue! BUT NOW, I'm having performance issues on iMessage, very slow response or the keyboard will freeze for a few seconds not showing my input, then suddenly it all appears! VERY ANNOYING ISSUE, tried restarting and even restore from back up with No Success! This buffer/lag sometimes happens with other apps as well, but keyboards in all other apps have yet to act up the same way!
Maybe any user experiencing the same issue?
