As a result, the affected user flocked to Apple's support forums to raise concerns about the iOS 10 problem. The users reported that if their iOS 10 gadget briefly lost service, it would fail to reconnect to any cellular network until the device is restarted.

One user said, "If my iPhone loses service for a while, like when driving past an area that is not covered or going inside of a building, the gadget will not reconnect to the cellular network once it is back in range." Adding that he tried toggling airplane made to make it search again but it does not work. "I have tried resetting network settings, but this also did not work."

It seems that iOS 10 users are only able to reconnect once they reset Network Settings from the Settings app on iOS 10 or reboot their device.

Apple-centric publication AppleInsider confirmed the issue first-hand. The publication reported that the existence glitch, which on Wednesday kept an editor's iPhone 6 offline in an area which normally has good reception was solved through a reboot.

The issue could be as a result of how iPhones connect to T-Mobile's LTE network. The network seems to start when the device gets temporarily off LTE coverage. However, an affected device remains completely offline until resetted yet it should bounce back online as soon as it gets reception again, MAC Rumors reported.

Users who routinely pass through areas with no service, such as underground parking or elevators could get really frustrating really fast.

Other suggested that the issue could be related to a carrier update, as the issue did not exist prior to this week for T-Mobile users.

It also seem that Telstra customers in Australia have the same glitch.

For its part, T-Mobile confirmed that the issue is affecting iPhone 6 Plus, iPhone 6 and iPhone SE gadgets running iOS 10 on its network.

Neville Ray, the company's Chief Technology Officer announced that Apple is working on a fix for this iOS 10 problem promising to deliver a solution in the next 48 hours.
