I am on a family account. My phone is eligible for an upgrade on 2/2/16. The other phone is eligible for an upgrade now. If I transfer the upgrade that is eligible now to my phone, will the other phone still be able to upgrade on 2/2/16?
Availability for upgrade is usually based on the birthday of your purchase or contract start date. Unless you paid for your phones in full from the start. Basically your not eligible for upgrades until your phone is paid off or close to it and they may offer you a promo
No. The contract term can't be switched from one line to another.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
You could put the new phone on your line, then put the new phone for your line on the other in February, but the contract dates won't flip flop, just as Ann154 said.
