Apple confirms that a small number of iPhone 18 Pro Max models on AT&T experience cellular connectivity problems, including cases where devices lose cellular service and cannot make calls. The issue is addressed through updates, but Apple says that phones that have already lost service will require a hardware replacement.
According to multiple outlets, Apple has released a software update (iOS 27.0.1) along with a carrier settings update to prevent additional devices from being impacted. Android Authority reports that Apple has already rolled out a bug-fixing update to stop further models from encountering the problem, implying the update prevents new occurrences rather than restoring already-affected hardware.
Across the coverage, the main difference is emphasis: some outlets highlight the availability and role of the updates to avoid future failures, while others focus on Apple’s confirmation that replacement is needed for users whose service has already been disrupted. All reports describe the affected scope as limited and tied to AT&T connectivity.
