Never in my life have seen such a fraud company.
Matrix is a complete fraud and you will definately regret if you take this SIM. It can be one of the biggest frauds of your life so BEWARE.
I had purchased a Matrix SIM card for my US trip and they provided me with a Micro SIM instead of a Nano SIM even after confirming it with them several times. After reaching the destination, to my surprise it was a Micro SIM card. I have been following up with the customer care service since then, and have not received any communication from them whatsoever. Wasted all my time, money and efforts as there has been no response from anyone from Matrix till date, it has been over 3 months now.
Issues
1- Default plan to be activate and as per my copy was 50MB data plan cost o SGD 12 But thye charged me for 100MB plan i.e SGD 26+ SGD3 - SGD 29
Beware consumers and save your self
Now after 2 months, their executive called me asking for payment. I asked them to tell me a reasonable amount that I can pay and settle the bill. They keep saying the invoice is correct and I have to pay full amount. Not sure where to go ahead from here. But, at least I can post it around internet and save others by opting for alternatives.
PS: Just noticed that all the positive reviews in this forum are labelled Fake:) should have been wary of this company earlier. Will welcome ideas on which are other good international sim cards primarily for data and incoming.
