Apple Advises iPhone 18 Pro Max Owners to Seek Replacements for AT&T Service Issues

This announcement was made on Friday, where Apple confirmed that affected units require a replacement rather than a fix through software updates. The company has introduced iOS 27.0.1 and a new carrier settings update aimed at preventing service failure for phones that remain operational. However, these updates will not restore functionality to devices already impacted by the issue. Users with non-functional phones should reach out to Apple Support, AT&T, or visit their retail locations to arrange for a replacement.

The problem is reported to affect only a small number of users on AT&T's network, although specific figures have not been disclosed. Complaints about the issue have surfaced across various platforms including Apple's support forums and Reddit, accumulating into the thousands. The affected devices typically display 'SOS' in the status bar and are unable to make calls, send texts, or use data unless connected to Wi-Fi.

Despite the implementation of iOS 27.0.1 earlier in the week and the carrier update being rolled out to users automatically within the next 14 days, Apple has not clarified the underlying cause of the issue. The U.S. models of the iPhone 18 Pro Max utilize a Qualcomm Snapdragon X80 modem, while international versions of the Pro Max and other models employ Apple's C2 chip. The relationship between the modem types and the service issue remains unexamined.

AT&T has stated it is working with Apple to address the issue and has recommended customers download the latest updates. This service problem appeared shortly after the iPhone 18 Pro Max launched on September 18, but some users received messages from AT&T on Thursday encouraging them to install the update, which also included fixes for other issues such as a bug affecting Face ID. However, many owners reported that their warranty replacement requests were initially rejected prior to the recent acknowledgment from Apple.
