charged for easy roam but didnt leave Canada

Let me flag a rep to help you out.

To avoid this from happening again, make sure to manually select your network to Koodo, so that your phone does not automatically connect to a nearby U.S. cellular tower. You will need to do this every time you restart your phone.

Hi ​@LisaP, we’ve checked the charge you mentioned and as it was accidental roaming we have added a credit to your account, you can check it out in your self-serve. 

To avoid future charges please make sure that the data roaming is off in your phone settings and you are manually connecting to the Koodo network.
