Apple and AT&T Have Yet to Explain Cause of iPhone 18 Pro Max Issue
In a statement shared with MacRumors on Friday, Apple said that iPhone 18 Pro Max users who have experienced an issue where AT&T cellular service does not work will need to have the device replaced , as the issue apparently cannot be fixed with a software update once it has occurred. That is a big deal, as it hints at hardware failure, but we lack details since Apple and AT&T have yet to disclose…
Apple and AT&T have yet to reveal the cause behind an issue affecting iPhone 18 Pro Max users on the AT&T network. Affected devices experience a failure to connect to cellular service, which cannot be resolved with a software update once it has occurred. Both Apple and AT&T have yet to disclose the underlying cause of the problem.
Apple spokespersons have stated that the issue is limited to a "small number" of iPhone 18 Pro Max users and involves a failure to make phone calls, send text messages, or utilize cellular data. Apple has released iOS 27.0.1 and an AT&T carrier settings update to help prevent the issue; however, users should ensure these updates are installed as soon as possible to avoid potential future problems.
The iPhone 18 Pro Max relies on Qualcomm's Snapdragon X80 modem for cellular connectivity in U.S. models, while variants sold in other countries use Apple's custom C2 modem. It remains unclear if the modem difference plays a role in the AT&T issue.
