I purchased Matrix 4G SIM at T3 Delhi airportfrom Matrix Desk after paying more than 5000 rupees for 28 days unlimited data and unlimited calls. The Matrix person present assured me that it will work. IHe put the SIM in my S8 Samsung mobile. I purchased SIM on 2nd May night. After reached New Jersey. I tried many time with switching on and off, and also by reinserting the chip. But it didn't not work. It is prepaid. Be aware this Mayrix is Bogus company.
