I currently have a basic phone, but I won't be able to upgrade for a few months. My friend upgraded and is willing to give me their old (verizon) smartphone. I was wondering if I could switch to a smartphone now and just add data without having to renew my contract? also, I'm on a family plan and 2 other smartphones on the plan share data, would I still be able to get my own data for my phone, or would I have to share with the other phones?
Lastly, would I still be eligible for an upgrade at the end of the 2 years even if I switch to a smartphone now?
