Apple iPhone 18 Pro Max cellular bug hits some AT&T devices
Key Points:
- Apple confirmed a "small number" of iPhone 18 Pro Max smartphones on the AT&T network lost cellular service, preventing calls, texts, and data, with affected devices entering SOS mode; this issue does not affect iPhone 18 Pro Max users on other networks or the iPhone 18 Pro model.
- Apple released iOS 27.0.1 and a carrier settings update to prevent future occurrences of the issue for AT&T users, but these updates will not reactivate already affected devices, which must be replaced.
- AT&T urged customers with iPhone 18 Pro Max phones to update their software and carrier settings, emphasizing their commitment to resolving the issue in collaboration with Apple.
- Customers experiencing connectivity problems with their iPhone 18 Pro Max on AT&T should contact Apple or AT&T support or visit retail stores for device replacement.
- The problem appears widespread, with thousands of complaints reported online, though Apple and AT&T have not disclosed exact numbers; this follows previous small-scale issues with earlier iPhone models.
