Apple Replaces Affected iPhone 18 Pro Max Units as AT&T Bug Blocks Calls and 911

Summary
Apple said a small number of iPhone 18 Pro Max devices on AT&T that have already lost service cannot be restored by software and must be replaced.
iOS 27.0.1 plus a new carrier settings update are intended to prevent the issue, but Apple said those updates will not reactivate phones already stuck without service.
AT&T users reported since mid-September that affected phones dropped into SOS mode, failed to place calls or texts, and in some cases could not reach 911 despite showing 5G signal.
The carrier settings update should arrive automatically within 14 days, while owners of already-failed devices are being told to contact Apple Support, AT&T, or visit a store for replacement.
