Is this allowed/supported? I will preorder to be dropped off at my house on the 24th as soon as possible. My plan is not currently up, but the main line on my account is. I can buy it saying it is for the main line and have it shipped here, put the phone in MY computer(not the main lines) and register it to my, ineligible upgrade, old sim? Sorry for a somewhat useless/already doen thread. i just want to know if this specific circumstance is allowed or not. After a couple yes/no please let it die.
