I went to France for an exchange program for a period of three months..Obvioulsy I wanted to take a number with me so that I wudnt have any issues there and after much research on International sim cards I decided to use Matrix Sim Cards. Not only was it economical when it came to tarrifs and data usage, the call quality is also great! And best part is they sent timely itimised bills which made it easier to justify my bill to my dad! Matrix, you guys rock!
