I live in Saskatchewan and pay ~50$ for 10GB of data/month. I'm not on a Sasktel plan, as I found a cheaper option through one of the privatized networks, however Sasktel has a new subsidiary: Lum Mobile, to compete with the cheap plans like what I'm using. I know someone who has some discount at Sasktel and pays ~50$/month for 75GB(!) of data.
When I was in toronto the guy at the hotel had a 306 (saskatchewan) phone number because it was cheaper.
Sasktel is a great provider. I have fiber to the home in my house, for instance.
