Were you travelling near the border by any chance? 

I was in Windsor Ontario, so yes, across the river. 

I have flagged a rep to come and help you.

Wjhenever you travel near the border, I recommend you switch data roaming off and also switch to manual network and select Koodo in the phone settings, this would prevent the connection to a US tower when near the border.

For more info about how to prevent accidental roaming charges, please check out this article https://community.koodomobile.com/plans-services-232910/easy-roam-understanding-how-you-will-be-charged-while-traveling-7811296

Hello @KristineMc 

Sometimes the device is going to catch the network on the other side.

It's a world-wide situation, since the device settings are set to automatically search for the strongest signal.

You can change that in the settings of the device and set it to Manual Network Selection, after it's done searching, you select Koodo and it stays connected to Koodo, even near the border.

I would also advise to keep Data Roaming off while in Canada. This will avoid any accidental charges. We have a great help page here: https://community.koodomobile.com/plans-services-232910/easy-roam-understanding-how-you-will-be-charged-while-traveling-7811296

We verified the day with the charge and confirmed accidental roaming. A credit was applied for the fee and will update within 3-5 minutes in the Self Serve account.
