A friend and I are backpacking around Europe at the end of the year. We are curious; what is the cheapest phone card available to make calls to each other?

We are traveling to France, Netherlands, Germany, Czech Republic, Austria, Italy and Spain.

Cheers

I use Onesuite prepaid phone card for long distance calls and its accessible to the countries you mentioned, meaning Onesuite have access numbers that you can call to use your Onesuite account for calling back home or calling within Europe or anywhere for that matter. It also has VoIP feature and it comes handy expecially if there is no available phone around but you have a computer with internet.
