Some users of the iPhone 18 Pro Max are encountering problems with AT&T cellular connectivity and eSIM provisioning, as reported on MacRumors Forums, Reddit, and the Apple Support Community. These users are unable to make phone calls, send text messages, or access data using the AT&T network. The issue is specific to the U.S. version of the iPhone 18 Pro Max, which features a Qualcomm cellular modem.
In contrast, the iPhone 18 Pro and iPhone Duo, as well as the iPhone 18 Pro Max in other countries, utilize Apple's C2 modem. It remains uncertain whether the Qualcomm modem is the root cause of the problem. Apple is currently testing iOS 27.0.1, which is anticipated to be released soon. It is hoped that this update will include a carrier update that resolves the AT&T connectivity issues.
