Apple is aware of and investigating an iPhone 7 and iPhone 7 Plus issue that can result in the loss of cellular service after turning off Airplane Mode on the devices, according to internal documents obtained by MacRumors.
In the meantime, Apple has advised authorized service providers to instruct customers to restart the affected iPhone 7 or iPhone 7 Plus. If no service persists, Apple advises customers to
remove and re-insert the device's SIM card.
In a video shared with MacRumors by reader Yasser El-Haggan, an iPhone 7 can be seen with no service alongside an iPhone 6s with two bars of LTE after Airplane Mode is toggled off on both devices. Both of the iPhones are said to be AT&T models, which means the iPhone 7
has an Intel modem rather than a
Qualcomm modem used for Verizon and Sprint models.
El-Haggan said he took his iPhone 7 to an Apple Store, where the Genius Bar swapped out the device with a new one. The employee had allegedly seen the issue on a few previous handsets, and he immediately replaced the device per Apple's instructions in lieu of running a basic diagnostic test. Apple appears to have replacement iPhone 7 models reserved for these scenarios per standard policy.
