Apple has acknowledged a bug affecting a small number of iPhone 18 Pro Max users on AT&T's network, causing devices to display an 'SOS' symbol and lose calls, texts, and data service. The company says iOS 27.0.1, released earlier this week, along with a new carrier settings update, should help prevent the issue, though it hasn't fixed phones already affected.

Some iPhone 18 Pro Max owners on AT&T's network reported losing all cellular connectivity, including the ability to dial 911, according to MacRumors, which estimates thousands of customers affected. Apple is rolling out an iOS 27.0.1 update alongside a separate carrier-settings patch to prevent the issue going forward, but says these fixes won't restore service on phones already affected. Apple told CNET it will give free replacement devices to those customers, who should contact Apple Support or AT&T.
