I'm upgrading a phone on my account from a F3Q to Galaxy S7 on Tmobile. Can I just take the SIM card out of the F3Q and put it in the S7 and be done with it or do I need to call Tmobile up and have them activate the new SIM card and then transfer the number over? Because that way it going to cost me $10 fee. The Galaxy S7 takes a nano SIM. The smallest size SIM. Not sure what size the F3Q takes as I don't have the phone here in front of me.
