I would rather say that I experienced a Matrix Sim Card than just use it. I rented their services for UK and they were very good. Actually they were better than the usual airtel sim card that I have always used. The services offered at the cost of Rs 3000/- was a steal deal. Close to 5GB free data and free call back minutes to India, all bundled in one sim card. It was way better than me spending thrice as much on my Airtel number everytime I travel.
