I’ve been using fizz for 4 or so years.
They use Videotrons network. You’re covered well in the Ottawa area. Elsewhere in Canada you roam on the other carriers, but you’re able to use your plan as you always would. You only get charged more if you roam more than you’re at home for 3 months in a row.
Overall I’m very happy with the service. Data rollover is such an amazing thing.
Sasktel’s MVNO, Lum Mobile, has a relatively unique pricing structure where you pay for a bucket of data, and it lasts until you use it. You can have calls and SMS get deducted from that data bucket. Ends up a lot cheaper for me and it’s good for people whose usage might vary month to month since you don’t feel like you need a plan to cover your busy months, and you actually have an incentive to reduce usage rather than just having “unlimited” things.
Downside is to get the best rate you need to pay for the year up front, but for about $425 including taxes and fees I’ve got a whole year of service. Equivalent to about $30/month plus 911 fees and sales tax.
