I am thinking about getting an IPAD. I have a HTC EVO 4G phone that I use as a hot spot for my laptop. Can I also use this for the IPAD? Would I have to pay any addtional fee's or hook up fee's? We travel a lot in our RV, and thought the IPAD would work really well. Will I be able to pay bills from it also? Not sure which one I will choose as of yet. So any tips would be greatly appreciated.
