As many of the MSians have already written many of the things about reliance data card, I only want to say that really in this service reliance is lacking very badly. No doubt reliance is known in the market for his quality products, upto the mark service. But in the case of data cards I will only say one thing "Poor product".
I used this product for around 2 months but frustrated from the speed which I was getting also there was no reliability regarding connection and when I tried to contact service providers they were also unable to satisfy me.
