Hey guys, so I have 4 lines on my vzw acct, 2 have unlimited data for smartphones grandfathered in, 1 is a vzw mobile broadband 5gb/month card, and 1 is a regular phone. The regular phone line is able to upgrade now at a discount price. If i buy a smartphone at a discounted price, with the data and stuff could i think somehow switch the new phone to my unlimted line and keep my unlimited data plan? Or is it not possible? I just wanted to make sure if it is possible that I would keep my unlimited data and how to go about it. Thanks so much!
