SOLUTION! SOLUTION! SOLUTION! Well, I had the same problem, went to Apple where they told me to backup and reset the phone. I won't starting to that procedure so much, so I decide to search for a solution on the net. I find a lot of things, as resetting network setting, turn on and of flight mode. change and check setting for the cellular network etc. etc. nothing worked. As least I readed something about, taking your simcard out (fysically or re-install e-sim) to solve the problem. And guess what!! PROBLEM SOLVED :) I can connect my non-APPLE devices again :) So just try- No you have YES you can get :) Have a nice day! ;)
