I am trying to sell my Rezound and eventually buy something else off contract, but I will have to sell my Rezound before I buy the other phone. So I will be going back to my Droid X for a little while between phones. My question is, can I just activate my DX from home by doing it online or calling the activation number? This is how I did it in the past between 3g phones, but I just want to make sure my Rezound will be completely deactivated before I sell it. I am also assuming that when I get another 4g phone, I will just have to go in to Verizon and get a new sim card since the one that is in my Rezound right now won't work. Is this correct? Thanks!
