Good experience using matrix sims--- I had used a matrix sim on a friends suggestion when I was going to Switzerland and realised it was way too convenient to carry a number before hand than actually getting one from there. It's more like wasting the currency in buying and the recharging while with matrix I just had to share my credit card details as security and they agreed to me paying by cheque instead. It didn't turn out to be as expensive as i thought it would be. Good recommendation..
