If you call a USA number while you are in Canada.
Pay-per-use int'l long distance rate : $0.50/min
With Int'l long distance saver Add-on($3/mo): $0.05/min
Also it will use your anytime minutes if you make calls during day time.
If you make calls a lot(more than 3.5 hour/mo) you might be better to pick "U.S. Unlimited Add-on"
Monthly long distance Add-ons
