Apple has confirmed a critical connectivity defect in the iPhone 18 Pro Max, affecting AT&T users in the U.S. The defect, which leaves devices stuck in "SOS mode," cannot be fixed with software updates, forcing Apple to replace affected units entirely. This marks the first time Apple has committed to full hardware replacements for a launch-period defect. To prevent further issues, Apple has released iOS 27.0.1 and an emergency carrier update.

In South Korea, similar complaints have surfaced, but Apple Korea has not issued a response, prompting accusations of unequal treatment. Analysts suggest the defect stems from a fundamental hardware flaw, raising concerns about Apple's quality control processes and its ability to manage customer expectations across regions.

Investment implication: Apple's replacement program could result in substantial costs if the defect is widespread. For you, this raises questions about Apple's ability to sustain margins and customer trust, particularly in competitive markets like the U.S. and South Korea.
