$$$ for Intl Calls with Sprint NW 40,000
I talked with Sprint about international calls before signing up on this one - you can not get any plan for discounted intl calls with this promotion - their call charges start at $1.28 per minute to Canada! (as another poster noted)
So, if you want the 40,000 you need to have 18 months of calling card calls for intl - I guess that is how they make their money.
