How to Activate new iPhone 4s?
So I got an iPhone 4s today and the people at the store told me I could easily activate it myself. So I brought it home to figure out. I'm upgrading from a basic phone (Samsung Reality) and my plan is upgraded too, but I can't seem to figure out how to transfer the phone number and get service on my iPhone! Like, I can still call people and text on my basic phone, and I can't on my iPhone. How do I transfer the number and the service? Please help!
Added (1). They did say they could activate it for me, but I asked if I could do it myself as I was in a hurry to get home.
