Really affordable plan with great offers --- I was traveling to Chicago and my father got me a great deal from his office that has some tie up with Matrix international sim cards. I hadn’t heard of it earlier but always knew that whenever my dad traveled  he carried a number before he could even start his travels. So this time he got me a sim card for US with some 16 hours of calling to India free and free unlimited local calls. Since I was traveling for an exhibition, this perfectly suited my plan. We just had to pay some 4000 Rs for the entire plan. Something that I was happy with and their service in Chicago were also really good. Practically no issues at all. It was as smooth as using their services there. I didn’t pay anything more than those 4000 rs  J
