The european comission has setup an international roaming factsheet.

http://europa.eu.int/information_soc...g/index_en.htm


You can get sample roaming rates applicable beased on your
operator/country of origin.

So if you travel to europe and intend to get local SIM cards, this site
can be quite useful to see how much you will be paying for a 4 minute
call when in a different country (eg: a french SIM card in england).
