From the fine print here. I'd give Telus a call and see what they say, this may be out of date.1 HSPA Prepaid clients will have access to voice and text services only at this time. HSPA Prepaid clients will not have access to data services, such as MMS, web browsing, email or downloads such as ringtones, games and images at this time.
Since there are no minutes on prepaid but cash and minutes are charged at 20c in the account, data should work. Unless of course you don't have cash to cover the 911 fees then maybe they could cut you off.From TELUS' site:
Clients will receive unlimited data for 30 days every time they purchase or renew the Data + Messaging 20 add-on. On March 20, 2011, Data + Messaging 20 clients will receive 250MB of data regardless of when they purchased or renewed the add-on. The 250MB will expire with the expiry of the add-on. As of March 20, 2011, the pay per use and overage rate for prepaid 3G+ clients will change to $3/MB
