Initially I am also attracted to matrix through advertisement like everyone.
After I got this sim and when using this.i am really feel very bad.bcz
This mobile operator signal strength only in cities and no coverages in small cities.really poor I think.
Then sim charges and calling charges too high when compare with other network operator.
Customer service is really pathetic.no one response properly.
Once you bought this sim.then you have ready to take risk.
Better to avoid this matrix sim.is my humble opinion.
If you r ready to pay more money even without using this sim.then go for it.
Matrix is not user friendly and not value for your money.
