Apparently for some iPhone users, seven isn't a lucky number.

Apple is offering free repairs to owners of the "small percentage" of iPhone 7 devices that may be displaying a No Service notice in the status bar even when cell service is available.

In a support page notice late Friday, Apple said the glitch stemmed from a faulty component on the gadget's main logic board.

The problem phones were manufactured between September 2016 and February 2018 and sold in the US, Hong Kong, Japan, China and Macao, Apple said. Three model numbers are eligible for the gratis fix. In the US (including Puerto Rico and the Virgin Islands), Hong Kong and Macao, the model number to look for on the back of your phone is A1660. In Japan, it's A1779. In China, it's A1660 and A1780.

The iPhone 7 glitch comes on the heels of Apple's controversial handling of battery issues with older iPhones. Without informing users, the company had tuned its iOS software to slow down the performance of the phones in order to prevent sudden shutdowns. It has since apologized for that secretive behavior, updated iOS to give users the option to allow the slowdown or not, and offered owners of its older phones, including the iPhone 7, low-cost battery replacements.
