Yes they do. You need to make sure that they properly configured your account with a blackberry plan. Have you set your BIS? If yes, then go back in there and send the service books and also go to options, advanced, host routing table and select register now. One good source to get a quick fix is their
forum where they have a live chat who are tech savy on BB's they will go over your account and will most likely be able to solve it while you are on line with them. Oh yes, fdo you see EDGE or GSM in caps, if not that would be a big issue for you and you would need to be in a diferent area where you will get those.
