Hi Claire, this option is actually for calling from Canada to the UK.
Currently Koodo doesnt have Roaming packages for outside of north America.
Your phone may still work however, check back here in a few minutes while I get you a link to check how your service may work In UK Edit: here's your link: http://help.koodomobile.com/coverage-long-distance-and-travelling/travelling
Alternatively, you can unlock your phone and get a local sim once you get to the UK
