I had heard a lot about matrix SIM cards from my friends and
for the last couple of times, my Airtel number was giving much woes and
worries internationally so this time decided to give Matrix sim cards a
shot. Good first time interaction with their sales guy Rahul. He
explained the process clearly of how it would be charged on the card and
so on. Also checked the SIM card in front of me whether its receiving
proper signals or not. I mean I would have hardly spent 10 minutes with
him and I had my Matrix Sim with me. That was a good experience. The
only issue that I faced was when I landed and exchanged sim cards I had
no signals until I stepped out of the Airport. I gave it a shot again
after stepping out, and voila it was receiving proper network. Data was
working fine. I managed to inform my family that I had landed safely in
London. Matrix was way better than my very own Airtel sim. Cheaper also
I would say. Overall good experience with them.
