If we are in an environment where a mobile connection is not permitted, such as in an airplane, we can activate airplane mode on the OnePlus smartphone.
In this case, all mobile, WiFi and Bluetooth connections are disconnected, preventing the sending and receiving of data.

Note: If we enable the airplane mode, we can subsequently turn on WiFi, for example, to connect to the Internet.

The airplane mode can also be (de)activated via the quick settings.
