I need a number to able me to call or text him?

How old are you?

If your parents took this action it was probably for your own good. You should be discussing with your parents why they did, not trying to go behind their backs.

First no, the phone will still be coming from that number.

The second is why are you calling the number ( to allow it to work) if you are not suppose to be talking, that means you don't call them either.
