can't i connect to the internet worldwide with bb storm......help

i travel a lot and i was wondering if i could connect my phone worldwide because i even can get that phone to work here in canada......if it is not possible i probably should sell this bb storm and get something else with wi-fi connection...
can any one please give more info on bb storm ....
thanks...

I am ASSUMING yes because I know the sim card in the back is enable you to use the phone worldwide on GSM networks. I would think that you would be able to use other 3G networks for data. Great question though and hopefully someone not as new to BB's as me has a difinitive answer.
