How to disable SIM card on phone ? Flight mode to turn it off ?

How can I disable using of SIM card on smartphone without removing it ? Does activation of airplane mode turn off SIM card ?

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.
