Apple is rolling out a new AT&T carrier bundle update for iPhone 18 Pro Max devices running the iOS 27.2 beta, bumping the bundle from 72.0.2 to 72.0.3. The fix follows reports that some AT&T users lost cellular service and saw "SOS" in the status bar; affected units still require hardware replacement.

• Carrier bundle update moves AT&T version from 72.0.2 to 72.0.3
• Issue affected only iPhone 18 Pro Max with Qualcomm modem
• iPhone 18 Pro with Apple's C2 modem was unaffected
• Devices that already lost service need hardware replacement
