A very peculiar problem was found in some units of iPhones 7 and therefore Apple today announced that it is starting a repair program for the affected devices.
The problem arose there in September 2016, causing the devices to show the message “No Service” (“No Service”) even with cellular coverage available.
According to Apple, the problem is caused by a failed logic board component and affects only the A1660, A1780 and A1779 models sold in China, the United States (including Puerto Rico and the Virgin Islands – models sold by Sprint and Verizon), Hong Kong, Japan and Macao; the devices in question were manufactured between September 2016 and February 2018.
The support article states that “Apple may restrict or limit the repair to only the regions where the devices were purchased”. Still, if you live in Brazil or any other country not mentioned above and you happen to have purchased one of these problematic devices, it never hurts to try going to one of the Apple stores (or Apple Authorized Service Centers) and see if they can help .
Apple also said it will contact customers by email who may have paid for a repair related to this issue to arrange a refund. If you have by chance paid for a repair related to this issue and you do not receive an email from Apple by the end of March 2018, please contact the company.
