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 the underlying cause of the issue.
