The Unlimited Messaging base plan gives you unlimited text and picture messaging 24/7 for 30 days and there are no pay-per-use charges, unique only to Koodo. Remember with this base plan, you can’t make any calls or receive calls on your phone. If you'd like to make or receive calls, then simply add a Talk booster. They start from $5 and do not expire! That means that if you don’t end up using all your minutes, they’ll just carry over the next time you renew your base plan.
