Hello VZW Community, tomorrow morning I will be pre-ordering the Galaxy S7 Edge. My line doesn't have an upgrade available for it, but my mom's line does. I have been searching the web about this for a while and haven't found any solid answers. I know that to start off I will need to just fill out the entire preorder using my mom's line for the upgrade. My mom and I both have HTC One M8s right now, so my SIM will already fit the GS7E without me having to get a different SIM activated. My question is this- once the phone arrives, can I just put my SIM card in it and call it good, or does the phone need to be activated with my mom's SIM first, and then I can switch my SIM into it? If neither of those are valid, what is the process that I have to go through? Thanks!!
