I made a call today that said it was roaming and I got two texts from Koodo that said I was roaming and welcomed me to the US... but I was just outside Sooke on Vancouver Island. Will I be charged roaming fees for this call even though I was in BC?
I suggest you wait until your next bill comes out to view your total charges. The good thing is that we'll be able to make the necessary verifications to find out where the call originated from, so no worries.
However, to prevent this from happening in the future, I would also go with what Robert suggested :)!
