If you had it and now do not - presume nothing has changed on your account.
But of course the first thing rogers will do if you call in will be to check and make sure you have a BB data plan.
I.e are you provisioned onto blackberry.net
perform a register now.
options - advanced options - host routing table: do you see anything in there?
Perform register now.
Does it queue or does it send?
If it queues perhaps your phone says GSM rather th an EDGE.
call into rogers and complain
