AT&T has texted iPhone 18 Pro Max customers urging them to update to iOS 27.0.1 to resolve cellular issues affecting call, text, and data functionality, including 911 access. The carrier claims the update will fix problems where some devices cannot make or receive calls or messages. However, users report the update does not address their ongoing issues.
The problem is believed to affect only a small number of iPhone 18 Pro Max users on AT&T’s network. Apple has released iOS 27.0.1 but has not confirmed it resolves the call problem, nor has it publicly acknowledged the issue. AT&T’s messaging suggests optimism about the fix, though some users remain dissatisfied.
One user, Rod Santiano, noted the update only addressed Face ID and touchscreen bugs, not cellular failures. He reported his device was replaced after testing showed no faults, and the replacement works. Users experiencing issues are advised to contact both AT&T and Apple support.
AT&T maintains a device help center, and Apple offers general support pages for assistance.
