This a warning if you live near the border and have the easy roaming feature turned on. You will be charged the daily easy roaming fee if you cell happens to lose the Koodo network and roam into the U.S.
No doubt many of these $7 or $8/day roaming fees will not be caught by folks.

Go into the network settings of your phone. Take it off "automatically selecting a network" and let it manually select a network. After your phone searches, select Koodo. Your phone will not be able to roam now and it will only connect to Koodo. If you ever do want your phone to be able to "roam" you'll have to change it back to automatic.
Contact Koodo to explain what happened to dispute the roaming charge.
