Airplane mode is sometimes called offline mode. It usually turns off wireless connections. This includes connection to Cellular network and in case of some devices also Wi-Fi and Bluetooth.

When connection to cellular network is disabled, your phone is not communicating with cellular towers, so you can't make calls, send text messages or use mobile data to access the internet.
