Same here in Norway. I think most (all) European countries do the same.

The only exception is if you are in another country. In that case the caller only pays as if the call was domestic, and the other has to pay the extra costs. The providers are required to allow you to set a maximum limit on your costs for your phone use outside your country, so you can't be surprised by huge bills.

The limits are regulated by the EU law and include Internet access (data transfer).
