AT&T calls failing for a small number of iPhone 18 Pro users

AI-summarised brief · reviewed before publication

A tiny subset of iPhone 18 Pro and Pro Max owners on AT&T are unable to place or receive cellular calls, though Wi‑Fi Calling works and the signal may stay on SOS. The problem, reported by AppleInsider listeners and Reddit users, appears linked to eSIM activation and began immediately after the devices’ launch. AT&T has acknowledged the issue and suggested affected customers revert to an older iPhone model, while Apple has not confirmed the fault. Some users have received device replacements through Apple support, but proposed workarounds on forums have shown inconsistent results. AT&T advises contacting both its and Apple’s support channels, and notes it will not support the upcoming iOS 27 Handoff feature that allows a single number on two iPhones.

💡 Why It Matters
