I just purchased a 256GB iPad Pro 12.9 for in store pickup (estimated for this Thursday). I entered in all my Verizon info on BestBuy.com and it's going to be a simple tablet line added to my Verizon Unlimited plan. Unfortunately, I'll have to pick this up during my lunch break and will have less than an hour. Will the cellular department have to do any sort of activation or will I be able to just pick it up and do the rest myself? Just a little worried due to the time restraint that day. I got this with the $250 off deal for a 2 year contract with Verizon. Thanks!
