Key Points:
- AT&T has acknowledged cellular connectivity issues affecting some iPhone 18 Pro Max devices on its network and is urging users to update to iOS 27.0.1 immediately, despite many users reporting the update does not resolve the problem.
- The issues involve inability to complete calls, texts, or use data, with devices often entering SOS mode; the root cause remains unconfirmed and Apple has not publicly addressed the situation.
- The U.S. iPhone 18 Pro Max is unique among the new models for using a Qualcomm cellular modem, whereas other models and international versions use Apple's C2 modem, though it is unclear if this contributes to the problem.
- iOS 27.0.1 update notes do not mention fixes for cellular issues but address a Face ID problem; further software updates or hardware fixes may be needed depending on the investigation's outcome.
- AT&T's text warning about potential texting failures highlights the severity of the issue, with thousands of users discussing the problem across various online forums.
