Matrix Interantional sim cards are very traveler friendly plus they have a very strong customer support team as well --- I was looking an international sim card for the US since getting one over there is not as easy. I decided to carry a matrix sim card and was happy that I did. Their network coverage is very good. Their 65$ plan is perfect for a 20 day travel with 1 GB data and a lot of free calling minutes to India. I was using this plan only and actually landed up paying just the rentals as my billed amount. Had I not got a matrix sim, buying a pre paid sim in the US would have been very difficult. I tried just for kicks and wasn’t to happy with their response. So team Matrix , Thanks !!
