Today, Apple launched a repair program for iPhone 7 models that are impacted by an issue that causes them to have no cellular service in areas where cellular coverage is available.
Hints of this bug first appeared in September 2016 when Apple launched an investigation into iPhone 7 devices that were displaying a “No Service” message after customers enable and then disable Airplane Mode.
The company says that the issue, which is caused by a faulty logic board component, impacts a “small percentage” of iPhone 7 devices. Apple is offering repairs to the affected devices for free.
Apple has narrowed the component flaw down to a batch of iPhone 7 units manufactured between September 2016 and February 2018 and sold in China, Hong Kong, Japan, Macao and the United States. According to supplied information, model numbers eligible for the repair program are A1660 or A1780 in China, A1660 in Hong Kong, Macao and the U.S., and A1779 in Japan. The model number on the iPhone 7 can be found on the markings on the device’s rear aluminum chassis.
Users who believe they are experiencing the issue should take their device to an Apple retail store or an Apple Authorized Service Provider for inspection.
