Call the switchboard. Some SIM cards do not display the phone number in the settings no matter which phone you insert it into. In this case, you can call the SIM card provider's switchboard to ask.

If you are calling from a phone with a SIM card that needs to know the number, the network operator can look up the phone number right away. If not, you should hold the SIM card in your hand to read the serial number on the card out loud to them.
