You Might Need to Replace Your iPhone 18 Pro Max
Lifehacker • • technology
Key Points:
- A small number of iPhone 18 Pro Max units on the AT&T network are experiencing a cellular connectivity issue, showing only an "SOS" icon and losing the ability to make calls, including emergency calls.
- Apple has released iOS 27.0.1 and a carrier settings update from AT&T to prevent this problem, urging all iPhone 18 Pro Max users to install these updates promptly.
- The updates can prevent the issue but cannot fix devices already affected; users with non-working units must get a free replacement from Apple or AT&T under warranty.
- The problem appears limited to the iPhone 18 Pro Max model using Qualcomm modems on AT&T, with no similar reports for the iPhone 18 Pro, which uses Apple's own modem.
- Users can manually check for the carrier update via Settings > General > About, though it should install automatically within 14 days.
