Error 'SIM not supported' on iPhone 14 Pro Max Hello! Hopefully someone here can really help. I have an iPhone 14 Pro Max that I’ve used for some time now on T-Mobile. I recently went to switch carriers and in the process found that the phone is still carrier locked to T-Mobile. The phone is now stuck on an activation page saying “Sim Not Supported”. I have tried everything to delete the eSIM. Factory restored 4 times. Went in to T-Mobile and they couldn’t do anything. Went in to Apple and all they did was reset it. The phone is currently rendered useless for seemingly a software design flaw. Any help would be appreciated! [Re-Titled by Moderator]
