AT&T Warns iPhone 18 Pro Max Outages May Block 911 Calls, Urges iOS 27.0.1 Update

Summary
AT&T texted iPhone 18 Pro Max customers to install iOS 27.0.1 immediately, warning some devices may be unable to make calls, send texts, use data or reach 911.
Thousands of users have reported similar outages in forums and support communities, with many saying the update did not restore service and their phones still drop into SOS mode.
Apple's iOS 27.0.1 release notes mention only a Face ID fix for iPhone 18 Pro models, and Apple has not publicly commented on the AT&T connectivity problem.
The U.S. iPhone 18 Pro Max uses a Qualcomm modem while other new iPhones use Apple's C2 modem, but no link has been confirmed and a further software or hardware fix may be needed.
