I got a random phonecall from california and i answered it... lasted about 17 seconds. i have an unlimited canada plan. how much will i be charged for answering this USA to CANADA phone call for 17 seconds?
As long as you receiving that call with "you" inside of Canada you'll be fine. If you have an "unlimited Canada" i'm assuming you have no local calling area restrictions (long distance) you'll be alright too.
