I did a buddy upgrade on my wife's line to get the Galaxy Note 2. My wife just has a regular flip phone and doesn't want a smart phone. That being said, the Galaxy Note 2 arrives today sometime. I have a Galaxy Nexus right now. Could I just swap the SIM card in the devices and be up and running or do I have to call Verizon and swap phones? I know my wife's plan and phone won't change unless the SIM gets activated. May as well remove the SIM if I don't need it. Your thoughts?
