Apple Admits Faulty iPhone 18 Pro Max Requires Physical Replacement

Apple has officially acknowledged a severe connectivity issue affecting the iPhone 18 Pro Max, which prevents calls and internet access and cannot be fixed with a software update. The company has instructed service centers that affected devices must be physically replaced. This points to a significant hardware defect, possibly in the motherboard or communication components.

The problem is suspected to be related to the Qualcomm modem integrated into U.S. models of the iPhone 18 Pro Max. These U.S. versions use Qualcomm's Snapdragon X80 modem, while models sold internationally, including in Israel, feature Apple's own C2 modem. It remains unclear if the issue stems from a defect in the Qualcomm chip itself or incompatibility with local network frequencies, but the problem is currently concentrated in the American market.

Thousands of users in the U.S., particularly AT&T customers, have reported their new iPhones becoming unusable due to this fault. Apple and cellular carriers have not yet provided a detailed technical explanation or disclosed the number of faulty devices distributed.

This connectivity failure adds to a growing list of problems reported with the iPhone 18 series and iOS 27. Previous issues include screen freezes when dragging widgets, a bug silencing the alarm clock, sudden Face ID failures, and strict flight restrictions on the Pro Max battery exceeding 20 watt-hours.

For Israeli consumers, this situation serves as a reminder of the risks associated with purchasing devices through personal import from the U.S. Israelis who buy U.S. models due to price differences may encounter this modem issue and lack local warranty support for immediate replacement.
