Sorry if this is in the wrong subforum, but I wasn't sure which one best suited my situation.
I currently have a VZW contract and am using a HTC Rezound that I purchased from them. This coming Sunday, I will be out of contract and will be renewing with a new phone. I intend to mod my Rezound so that my mother can use it with Straight Talk. She currently has a Nokia Lumia that she bought pre-unlocked and is using it with her unlimited everything Straight Talk plan. I've found a few threads that are very helpful with my situation, but not having done this before I wanted to find out what I need in order to begin and what my consequences might be.
This thread has been helpful in getting me started. My phone is on software version 4.05.605.14 but my phone is not already "unlocked" like this OP's was, so I understand that I need one of the global roms such as this one. My questions lie more on the Straight Talk side. Can I use my mom's existing SIM card from her Nokia? Can she keep her current number? Are the problems with picture messaging/3G still going to occur? Will I need to call Straight Talk and pretend to be her for any reason?
Does anyone have experience that will be able to guide me, should I run into problems?
