I have 5 lines 4 with udp. One with an upgrade available 1 basic phone. I have a subaccount with two udp lines. One with upgrade available. I want to transfer the available udp upgrade to the basic line via best buy (I did this myself via best buy a while ago but don't remember the steps) can someone help me out ? And is it possible to transfer the upgrade of the udp line who has an upgrade on the subaccount to the basic line on main account and do the same thing? Or do I have to move the basic line to the subaccount first and do the same as my first scenario? Thanks.
