SaskTel
SaskTel has a new digital mobile service that lets you manage your own wireless service online while offering more affordable prices than the full-service model. Lüm Mobile doesn't have any monthly plans or monthly billing dates. Instead, you buy a membership to get access to data that never expires. You don't have to worry about losing unused data every month, and you'll only pay for the data, calls, and text you use. You can buy data any time you need it. But you will need to bring your own device to sign up for the service. You can learn more here.
