Apple is providing iPhone 7 owners with free repairs if they have one of the "small percentage" of devices that do not properly connect with a cellular network. 。

The affected iPhone 7 devices will show "No Service" in the status bar at times even when cellular coverage is available in the area. The defect comes from a failed component on the main logic board, according to Apple's website. 。

The affected devices were manufactured from Sept. 2016 to Feb. 2018 and were sold in China, Hong Kong, Japan, Macao, and the U.S., according to Apple.
