I had been burning my pockets with the international roaming everytime that i went to Australia. And this time around i opted for a Matrix Sim Card and honestly was quite relieved with the decision. Not only were the data plans affordable, but were superb! And the billed amount, it just made me smile at the end !! I really did save up big on my international bills. Looks like Matrix and I will be going a long way henceforth 
