GoKawiilAT&T tells iPhone 18 Pro Max users iOS 27.0.1 fixes network issues; users say it doesn't
AT&T sent a text to customers urging them to update their iPhone 18 Pro Max to iOS 27.0.1, saying it would fix problems with calls, texts, and data, including 911 access. However, Apple's release notes for iOS 27.0.1 only mention Face ID and camera fixes, and multiple affected users report the connectivity problems persist after updating, with phones still showing 'SOS' in the status bar.
GoKawiil's interpretation of the reporting above, not reported fact.
The discrepancy between AT&T's messaging and Apple's official release notes suggests the carrier may not have accurate information about the cause or fix, which could leave affected customers without a real solution while believing the issue is resolved. The problem appears tied specifically to the Qualcomm modem in the iPhone 18 Pro Max, as the iPhone 18 Pro with Apple's own C2 modem seems unaffected, pointing analysts toward a hardware or modem-software interaction rather than a simple software bug.
- AT&T texted customers claiming iOS 27.0.1 fixes iPhone 18 Pro Max connectivity problems, including potential 911 call failures.
- Apple's iOS 27.0.1 release notes mention only Face ID and camera fixes, not cellular connectivity changes.
- Affected users report the 'SOS' connectivity issue persists after updating, and the problem seems limited to the Qualcomm-modem iPhone 18 Pro Max, not the C2-modem iPhone 18 Pro.
