A:AnswerI just got an iPad for my husband and it was $10/mo to add the device to my plan. If you get an iPad without cellular you can just use one of your devices as a hotspot.
A:AnswerYou never need a new contract if you pay full price for the device.
I've paid full price for the last two iphones and simply added them to my Verizon service with no contracts.
A:AnswerYes, I purchased mine with the intent of only using it for WIFI and it works fine. Additionally, if you have an IPhone, you can use the hotspot on the phone to connect your IPAD to the internet, wherever you are.
