Cant . This is a multinational game. No one would undertsand the other.
You would still be able to talk to those from your country. and many know some english.
They said its prob because ppl are using sms to play
but they need chat BAD in the waiting room and/or in game
it would all be french or english fine with me
Remember the Mobile phone aspect. They would have a really hard time using the chat.
Separate it out somehow, i know techies can do it
UR makes most the money withtheir mobile version (phone contracts etc) I doubt they want to degrade that product.
Europe cell tech is alot different then US cell tech.
(begin shameless plug)
Best solution would be to add a chat room on a fan site ... maybe URTournament.org (/end shameless plug)
