The iPhone 18 Pro Max Signal Blackout: Apple Issues Urgent Replacement Warning
Apple has officially confirmed a critical connectivity issue specifically targeting iPhone 18 Pro Max models on the AT&T network. The bug causes a total and permanent loss of cellular service that cannot be fixed via software once it has occurred. To mitigate the spread, Apple has released an urgent iOS update designed to protect currently functional devices; however, users who have already lost their signal are being instructed to return their phones for a complete hardware replacement.
