We got Matrix SIM cards for our travel to Bali via Singapore.

1)They told us our Singapore SIM would come with no extra charge - It did!
2) We were supposed to get some kind of tariff card by the sales guy - We didn't
3) To save on calls we were supposed to use some other code instead of country code - We were not informed about this.
4) In the info sheet, the only way mentioned to call any number in India was by using the country code followed by the phone number
5) People who called from India was supposed to be 6 per minute - They were charged Rs90 for 3 minutes
6) For a total of 25 min calls that we made we were charged Rs.3000
