Apple Says iPhone 18 Pro Max Users With AT&T Cellular Issue Need to Have Device Replaced
MacRumors • • general
Key Points:
- Apple confirmed a cellular service issue affecting a small number of iPhone 18 Pro Max users on the AT&T network, causing loss of calls, texts, and data connectivity.
- To address the problem, Apple released iOS 27.0.1 and an AT&T carrier settings update, urging all iPhone 18 Pro Max users to install the software updates immediately.
- Devices already impacted by the issue cannot be fixed through software updates and must be replaced; affected customers are advised to contact Apple Support, AT&T, or visit an Apple Store or AT&T location for a replacement.
- The problem appears isolated to the iPhone 18 Pro Max on AT&T, with no reports of other iPhone models or carriers being affected, and the root cause remains undisclosed.
- It is unclear if the difference in modem hardware between U.S. models (Qualcomm Snapdragon X80) and international models (Apple’s C2 modem) contributes to the issue, and no dedicated Apple Service Program has been announced yet.
