Apple’s iPhone 18 Pro Max shifted from modem split to hardware fixes
Across these reports, Apple’s U.S. iPhone 18 Pro Max moved from a regional hardware variation to a documented reliance on Qualcomm and then to an acknowledged connectivity defect that cannot be fixed in software. The pattern is a narrowing margin for Apple’s claim of uniform flagship hardware.
The three developments also show the issue becoming more serious over time. First came evidence that U.S. units differed from international ones on modem choice, then a teardown confirmed the difference against Apple’s own materials, and finally Apple accepted that some affected devices need full replacement rather than an update.
The issue has progressed from regional hardware differences to a confirmed modem discrepancy and then to a replace-only connectivity defect.
Apple said some affected devices need replacement
Apple then acknowledged a serious signal failure tied to the model on AT&T in the U.S. and said software will not correct it. The remedy escalated from product variation to hardware replacement, with no response yet from Apple Korea on similar complaints.

Teardown evidence backed the non-Apple modem claim
A later teardown confirmed the U.S. handset uses Qualcomm hardware instead of Apple’s in-house modem. That also exposed a mismatch between the device and Apple’s published specifications.

U.S. Pro Max units were shown with different modem hardware
Reporting first indicated that the U.S. version of the phone did not match overseas models on modem choice. That introduced the idea that Apple was shipping the same flagship with different connectivity parts by market.
