I am really thinking about finally signing up for Exede. Tired of my spotty cell phone wifi card. I know that I dont currently use 10 GB of data a month (my cell card is limited to 5 GB currently) But I also know that if I have faster internet I will probably use it more. So my question is if I am consistently going over the data limit, can I change my contract to go 15 GB or 25GB? If so does that restart my 24 month commitment?
