A:AnswerSure, it will work anywhere there is a cell tower nearby. It's like using the internet in your phone, only this is a hotspot and you can connect other devices.
A:AnswerYou can buy a Simple Mobile Data plan online or on a card at stores like Best Buy and I am sure elsewhere. The cards are just a way of paying for a plan - they have no SIM card - which is already in the device. You can top up on the the Simple Mobile app - if you burn through your data quickly.
