Thank you all for your thoughts/info. FYI, MCI told me that using their calling card to call the US would cost 3.99$ surcharge + 4.18$ for the 1st min. + 2.44$ for the following minutes. I guess I'll shut up for a while and if necessary, make short calls to ask to call back. If they get through, as you say.

Btw to Craig6z: I'm going to 'Carnivore' soon!
