If your iPhone 18 Pro Max always says SOS, you need to get it replaced

AI-summarised brief · reviewed before publication

Apple has identified a service‑loss bug affecting a small number of iPhone 18 Pro Max units on AT&T’s network, which can cause the device to display “SOS” and prevent calls. The company released iOS 27.0.1 and a carrier‑settings update on Friday to stop new occurrences, urging all owners to install both patches immediately. Devices that have already lost service will not be repaired by software; Apple instructs users to obtain a replacement, preferably at an Apple Store, though some AT&T corporate locations may carry spare units. AT&T says the carrier‑settings update will roll out automatically within two weeks, but recommends users trigger it manually via Settings → General → About. Affected customers should contact both Apple and AT&T support for assistance.

💡 Why It Matters

  • · The fix requires immediate action, and without a replacement the phone remains unusable, turning a flagship launch issue into a costly, high‑visibility service failure.
