Apple confirms that certain i Phone 18 Pro Max devices on AT&T’s network are unable to make calls or send texts, remaining stuck in SOS mode. The issue emerged recently and affects a subset of units sold through the carrier. Apple states it will replace affected phones at no cost to users.
Two software updates have been identified that can prevent the problem from occurring, but they do not resolve it once a device is already impacted. According to Apple, the root cause involves a compatibility conflict between the device’s modem firmware and AT&T’s network configuration during initialization. The company says it is working with AT&T to isolate the exact conditions triggering the failure.
Apple explains that while the two iOS updates can stop the issue from appearing on unaffected phones, they cannot reverse the state of devices already locked in SOS mode. Once a phone enters this state, standard troubleshooting like restarting or reinserting the SIM card does not restore service. The only reliable solution, Apple says, is a hardware replacement. Users are advised to back up their data before visiting an Apple Store or authorized service provider.
Customers can determine if their i Phone 18 Pro Max is impacted by attempting to make a call or send a text. If the device shows „SOS” or „No Service” in the status bar and fails to connect despite being in a coverage area, it may be affected. Apple recommends contacting support to verify eligibility for a free replacement. The company has not disclosed how many units are involved but says the number is limited.
What should I do if my i Phone 18 Pro Max is stuck in SOS mode? Contact Apple Support or visit an Apple Store to arrange a free diagnostic and potential replacement. Back up your data first using i Cloud or a computer.
Will the software updates fix my phone if it’s already affected? No, the updates only prevent the issue on devices that have not yet experienced the problem. Affected units require hardware replacement.
Is this issue limited to AT&T or could it happen on other carriers? Apple has confirmed the problem so far only occurs on AT&T’s network. No reports have been received from users on other carriers regarding this specific failure.
