I just ordered my Nexus 4, can't wait for it to get here. Will I be able to use the existing SIM card in my One S or will I need to go to Tmobile to get a new card? I'm new to this GSM life.

You can use your existing SIM card. Pop it out of the One S and then put it I to your N4. You may have to add or modify the APN settings for t mobile. I had to enter them for ATT.

Last question. Once I move over the SIM card and check the APN I should have a working phone on my TMobile service correct? Is there anything else I need to do?
