Apple to Replace iPhone 18 Pro Max Units Affected by AT&T Connectivity Glitch
Apple and AT&T are addressing a cellular connectivity issue affecting a subset of iPhone 18 Pro Max users on the AT&T network. The problem prevents affected devices from making calls, sending texts, or accessing data, including emergency 911 calls. Apple has released iOS 27.0.1 and a new carrier settings update (version 72.1) to prevent the issue from occurring on other devices. However, Apple confirms that software updates will not restore service for phones that have already lost connectivity. Affected users must return their devices for a free hardware replacement. The issue appears isolated to the iPhone 18 Pro Max on AT&T, with no similar reports on T-Mobile or Verizon networks.
