You may have a device that was affected. See [https://www.apple.com/support/iphone-7-no-service/|article from Apple] It starts off as a No Service issue. Before resetting the device check for Firmware Modem (in settings, general, about) if it exists, if not '''do not''' reset the device or it loops. As for work-around, it's board related, so someone will have to check that defective component and replace it more-or-less.
