TELUS - 3 year contract question

Bought a blackberry pearl 8130 yesterday; hell of a phone IMO. Have a quick question in regards to the data package. In order for me to get the phone for $99.99, i had to add the smallest data package onto the phone. Does this data package have to remain on the phone for the duration of the contract, or can i cancell this package? Any help would be appreciated.

Thanks,
AS

The data plan has to remain on the contract for the first year after that you can remove it for a pay per use data plan
