Apple mandates hardware replacement for iPhone 18 Pro Max units failing on AT&T network
Apple confirmed that a subset of iPhone 18 Pro Max devices on the AT&T network are losing cellular service, requiring hardware replacement. While iOS 27.0.1 and a carrier settings update prevent new failures, they do not restore service for already-affected units. The issue is isolated to the U.S. model using a Qualcomm modem, whereas the iPhone 18 Pro with Apple's C2 modem remains unaffected.
