Get a data only plan that gets you 3gb for 15 a month. Use Fongo or some other similar VoIP service and you get a Canadian number and the ability to text as well. Fongo charges 2-3 a month to text while calls are included. Text now is fully free but I find the quality and reliability less good. If you want it to be with Koodo then just the plan with the minimum amount of data you need I guess. Will you be prepaid or postpaid?
