1. I think it is all of your account information1. What type of data is saved to my VZW Sim card?
2. If I wipe and sell my current Note2 would I want to take out the Sim card?
3. Do I need to put my current Sim card in my next phone or does it not matter?
You can pop your vzw sim card in any phone that takes a vzw sim and it will transfer everything over to it that a gsm sime card would...
Hell someone even took a sprint Note 2, replaced the built in sim reader/card with a vzw aftermarket one and managed to get it working on VZW, albeit without LTE.
They mean account data. Your data plan, minutes, service plan is what is stored on the Sim. Take it out when you sell the old one and put it in the new phone. You wont need to call Verizon to activate the new phone.What do you mean by "transfer everything?" are you talking about account data or actual files, documents, images, etc.?
