You would have to add on of the US Roaming packages Koodo offers: https://www.koodomobile.com/add-ons
Your minutes/texts/data included depends on the roaming plan you choose. You do not get to use your normal plan in the states, its whatever it says in the roaming package.
Dont add the roaming package until the day you leave. If the roaming package runs out, log into self-serve, remove it and add it again and it will give you the full minutes/data/texts in the package
