While all of the bugs affecting the new iPhone 18 Pro and iPhone 18 Pro Max are only happening for a very small group of users, they are happening. Alongside the already reported Face ID restart bug, due to be fixed shortly, AppleInsider has been told of an AT&T issue.
The issue is that, for the affected users, cellular calls cannot be made or received. Calls work when using AT&T Wi-Fi Calling, but cellular signal strength either varies or stays on SOS only.
