@R-R: Not sure if they were blocked both ways. Last week, I tested one of their sim cards, and none of the above protocols worked. They opened up a bunch of ports on the mobile plan. p2p is bit torrent and the like. That is allowed under the usb stick plan for $55. You're right that in most cases, it is $5 cheaper to get the cheap voice plan plus mobile data plan rather than the usb stick plan.
