I too think you will have no problem.
My recent experience was flying to Hong Kong for the Sevens. Bought a data SIM pay as you go at the airport on arrival; put it in my Blackberry, waited about 3 minutes for the system to connect and I was as connected as at home - emails and BBM no problem. And very useful!
So I would say go ahead - what do you have to lose - a prepay data SIM to experiment should not be too expensive.
