GoKawiilApple issues separate AT&T carrier fix for iPhone 18 Pro Max on iOS 27.2 beta
Apple has pushed a new carrier settings update, version 72.0.3, to iPhone 18 Pro Max users running the iOS 27.2 beta on AT&T, following last week's fix for devices on the stable iOS 27.0 release. The update addresses the same issue in which some users lost cellular service entirely, with affected phones showing an 'SOS' status indicator.
GoKawiil's interpretation of the reporting above, not reported fact.
The problem appears tied specifically to the Qualcomm modem used in US iPhone 18 Pro Max units, since the modem-swapped iPhone 18 Pro has not reported the issue, which suggests a modem-carrier compatibility flaw rather than a broader iOS bug. Apple's decision to patch both the stable and beta channels separately indicates the fix required tailored carrier bundles for each software branch, and devices that already lost service reportedly still need hardware replacement.
- Apple released carrier bundle 72.0.3 for iPhone 18 Pro Max users on AT&T running iOS 27.2 beta.
- This follows a prior fix (bundle 72.1) issued last week for users on the stable iOS 27.0 release.
- Only the Qualcomm-modem iPhone 18 Pro Max is affected; the Apple C2 modem iPhone 18 Pro is not impacted.
