For our vacation to Singapore, my wife and I used a matrix sim card to stay in touch with our families back home. It was probably the best international sim card we have used so far, better than getting one there as well. When we landed there the sim started working, the good part was Ashish the sales guy from whom i took the SIM called me and checked if the SIM is working fine that was the best i could have expected from a sales guy and the billing was smooth too.
