Hello. I currently have an unlimited data line on my mom's Nationwide plan. VZW has increased my data to $50 from $30. I currently have a non-vzw iPhone 6 on that line. If I were to purchase a Verizon S7 Edge on DPP using the unlimited data line, would I lose unlimited data? If not, can I use my current nano sim in the S7 edge? Also, would I be able to go back and forth and use the same nano sim in either phone without losing unlimited data? Im worried because I've read over the internet that, and its my interpretation, that a phone's imei would be tied to that sim. Since I am not paying the full retail price of the S7 Edge, I would lose unlimited data as soon as I place that sim in another phone. By the way, the iPhone 6 was originally purchased from T-Mobile but has been paid in full and has been unlocked. Thanks
