Currently on a iPhone 5s which I bought used a while back. Before that I was using my Galaxy s3. I'd like to get a new phone without getting a new contract so I don't lose my unlimited data and messaging. If I buy the Galaxy s5 from best buy on a monthly routine payment option, would I be able to put my SIM card now into that phone and activate that phone via verizon wireless? Or is there any other way through verizon I could do this? Thanks. Edited: I looked on the forums and it all just confuses me. I've read multiple threads but I'm at a complete loss here. My plan from like 2012 is Month to month payments Unlimited data and messages Shared minutes.
