Are you close to the American border? For future reference, be sure to set network selection mode to manual, and pick Koodo from the list that populates. Your phone will only attempt to connect to Koodo. And you can turn off data roaming in your phone network settings as well to decrease the chances of getting a roaming charge as well, since data is constant and calls/texts are not.
