Apple to replace iPhone 18 Pro Max units over AT&T connectivity issues

Apple has confirmed a hardware defect affecting a limited number of iPhone 18 Pro Max devices, which prevents users from maintaining a stable connection to the AT&T network. The issue, which often leaves devices stuck in SOS mode, appears linked to the specific Qualcomm modem used in the U.S.-based Max model. In response, Apple is offering hardware replacements for affected customers. For those currently experiencing service disruptions, the company recommends contacting Apple or AT&T support for assistance. Users who still have connectivity are urged to update their devices to iOS 27.0.1 immediately. While this update does not restore service to already disconnected phones, it helps prevent further disruptions. Apple is also rolling out an automatic carrier update over the next two weeks to address the underlying software communication issues. Customers are advised to visit an Apple or AT&T store if they are unable to resolve the problem manually.
