iMessage activate failure after iOS 11.2.6
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.
