Yes you will be charged long distance rates from your cell. Way around high rates? Go to a 711 and buy an international phone card for $5.00. That should give you around 2 plus hours of talk time. Great find and good luck.

P..S. You may need to drop the zero after 31 depending on where you are. 31 is the country code for the Netherlands and from the US you need to dial 011 ahead of the country code. They should be 6 hours ahead of New York.
