How to re-initialize a new sim?

I have an external sim card holder linked up to the my phone. When I change the sim card in the external sim tray, I have to either re-start the phone, or open and close the phone's sim tray in order to make the phone recognize the new sim card.

Is there a way to make the sim re-initialize without restarting the phone or opening the sim-tray?
