Apple investigating iPhone 7 bug resulting in 'No Service' when Airplane Mode is turned off

Apple's new iPhone 7 and 7 Plus went on sale last week, although many models were already sold out by the time the two handsets launched in stores. However, the launch hasn't been as smooth as Apple would have liked so far.

After botching the iPhone Upgrade Program, leading to a lawsuit by irate customers, the company is also facing growing complaints due to issues with the devices themselves. Some iPhone 7 owners have reported that the device is 'hissing' during heavy usage, while others have had problems with the wired headset, which now connects to the phone's Lightning port, after Apple decided that that would be a superior solution to the dedicated headphone jack.

A further issue has also emerged, after details of internal Apple documentation were revealed by MacRumors. The issue occurs on some devices when exiting Airplane Mode, preventing them from reconnecting to a cellular service.

One individual said that he had taken his iPhone 7 to an Apple Store, where it was immediately replaced for a new one. The technician at the Genius Bar reportedly said that he had seen numerous devices affected by the same problem.

According to the internal documents, Apple is advising service providers to tell customers to restart the phone if the issue arises. If the issue persists, they should remove and re-insert the SIM card.

The problem is known to affect both the iPhone 7 and iPhone 7 Plus - although it appears to be confined only to those models with Intel modems, and not the CDMA-enabled devices which use Qualcomm modems instead. But it's not yet clear exactly how widespread the issue is, or if a more permanent resolution will be available to fix the problem on affected handsets.
