So most know about the BOGO on the maxx. me and my wife had two available upgrades on our family account and decided to bite with the intention of me getting a maxx and selling the other one. after googling a bit ive found that in order for the other maxx to have a clean esn, we would first have to activate the extra maxx, then go back and re-activate my wifes ip4, thus giving the extra maxx a clean esn. is that correct? also, when selling the extra phone do i also give the 4g lte card that came with the phone to the buyer? or is that in some way tied to our account? after selling the phone, does the buyer then just go into verizon for his/her own lte card? Id appreciate any clarification, thank you in advance. one more thing, this battery is INSANE.
