I am going to be travelling overseas for over a month, and would like to buy an MSN IM program for my 7100r. Im probably going ot use Verichat.

Anyways, my question is, what costs are associated with using an IM client overseas.

Am I charged per KB on my data plan, and am I charged roaming fees on top of that for all the time spent online?

Any help would be great.

Thanks
