This is for Verizon so I'm not sure how SIM card works exactly. I am using wife's upgrade and she is taking my 4s. I need to move my contacts and thing to the 5 and then clear the phone. But also need the 5 activated under my name and number. Not sure how easy this is. I heard if I do something wrong it takes a day for them to change sim. Not sure though. Any help please?
