Im curious if i can use my current LTE Sim in the rezound (it arrives tomorrow). I got it from a seller on Ebay so i dont think it comes with an LTE sim. I should be able to just do the whole thing online, right?
If the Rezound uses the standard SIM card size and not the micro SIM card, you should be to place the SIM card in the Rezound.
You can certainly also switch devices through your MyVerizon account.
Yes, it does. Sim cards carry user data on them, so a swap should be all that is needed.
