Reliable services from Matrix Sim Cards -- I was ytraveling to singapore for about 10 days for work and was handed over a kit from office with a matrix card and instructions for dialups. Very honestly i wasnt sure of their services since i hadnt come across some good reviews. But i had no choice than use it. Have to say when i started using it for my regular calls for work locally and back home in delhi and especially the data services. I was being frequently updated about my data consumption via emails. Was actually impressed with this.
