Guys please beware, matrix has the power to make you bankrupt. I had to cough up 25, 000.00 for my 2 months stay at US (that too I only called/received local numbers).Moreover it was supposed to be a student plan. My friends got a T-mobile from US and they paid only $100.00 for 2 months with unlimited voice and data. Mine was only for calling , no data involved. They work on a simple model, they know you will never return as a customer, so they will rip you apart the first time.
PLEASE FOR GODS SAKE DO NOT USE MATRIX. You will never come across such a fraud company.
