New AT&T Carrier Update Released for iOS 27.2 Beta on iPhone 18 Pro Max

Apple has issued an AT&T carrier settings update for iPhone 18 Pro Max users running the iOS 27.2 beta. This update addresses recent network changes, moving the affected devices from carrier bundle version 72.0.2 to 72.0.3. The rollout was noted by Aaron Perris on Friday.

This update follows a previous carrier adjustment for users on the public version of iOS 27, which aimed to resolve a cellular issue that had caused some AT&T customers to lose calls, messages, and mobile data on the iPhone 18 Pro Max.

Devices using the iOS 27.2 beta had been utilizing the older carrier version 72.0.2, while those on iOS 27.0 had received version 72.1. The new 72.0.3 version will now introduce the recent network changes for beta users.

Apple has previously stated that devices that have already experienced service loss will require hardware replacements. The recent carrier settings update is designed to prevent unaffected devices from encountering the same issues, rather than fixing devices that have already failed.

This problem has predominantly affected the iPhone 18 Pro Max on AT&T, making the latest update particularly significant for beta program participants.
