I'm trying to find an answer to my question by reading all of the FAQ's/previously asked questions and I'm just getting confused. I would like to switch my phone and my boyfriends phone to the new plans. I have -75$ left for my phone on the tab. It is my understanding I will have to pay this amount before switching to a new plan? My boyfriend has no tab as he has the BYOD 10% discount. I have read that in order to change his plan he has to upgrade his phone? I have also read that he can change the plan without upgrading and will lose the 10%. Can someone clear this up for me? Thanks
