Hello @BethanyCouture
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 do not see any charges just yet, however they can have a delay until they appear. We would have to wait for the new invoice to be released and if you see any charges that you do not agree with, let us know here and we will gladly look into it.
