I'm in BC and wondering if I should avoid using anything data like in case I get charged. I have the "Ultimate 65" plan.
"The wireless data usage included in your data plan can be used anywhere in Canada." - Source: Link
As far as I understand that, it means that you don't get extra charges for using data in a different province. I will still suggest that you contact Sasktel to be sure about this. Please let me know how it goes.
