You seem to be asking carrier-related questions about roaming...

Your blackberry will roam anywhere there are roaming agreements between your carrier and the countries carriers.

As for costs associated, you will need to contact your network service provider.

If you do not want to use any data while roaming and potentially saving money, you can switch your Data Services to "<I>Offf While Roaming</I>". This can be achieved by going into Network Connections and using Data Services, While Roaming switching it OFF.
