I assume the roaming fee showed up in your latest bill already. Let me flag a rep to look into it.

In the future, as your phone was prone to US tower connection, please disable data roaming and automatic carrier selection (manually select Koodo) when you are traveling near US border.

Hi ​@AngeG 

We have reviewed the details and we have been able to remove the roaming charge 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 more info about how to prevent accidental roaming charges, please check out the article shared by Dinh above.

Thank you!!
