If you have a smart phone, like a Droid, you can "root" it and get the wifi hot spot access without your carrier knowing.
I use mine when I travel and let 2 to 3 coworkers use the wifi hot spot to connect laptops and tablets.
Only issue I have is burns thru the battery real fast and I need to keep near an outlet in the airports to charge it.
