To prevent future roaming charges, you can turn off the roaming on your phone settings, and set your connection manually select to Koodo.

Hi ​@Kayla Anderson 

We have reviewed the details and we have been able to remove the roaming charge for the one day for the line ending in *844 in since it was triggered due to accidental data roaming, feel free to check the details in your self serve account when you get the chance.

For the rest of the roaming charges, data usage indicates the phone was not connected to Canadian towers for more than 6-7 hours. If you wish to dispute those further, you can send us a message on social media using the links at the bottom of this page or you can schedule a call back with the virtual assist.

We recommend switching data roaming off and also switch to manual network and select Koodo, this would prevent the connection to a US tower when near the border.
