Can i call rogers to switch sim cards?

My brother got an iphone 5 with a new sim card and i got his old iphone with his old no longer working sim card. Both phones are on rogers, i currently have a black berry. Is there anyway i could call rogers and get them to switch my number onto his old sim card or do i have to go into rogers to get them to do that?

You can't reuse an old SIM card. Once it's transferred, the old SIM becomes inactivated and can't be activated again. You will need to get/buy a new SIM that will fit the phone then transfer the info from the old SIM to the new SIM. Usually this can be done online through account maintenance or by phone.
