Hi .
This review will be based on reliance operator . I have used reliance gsm/cdma sim for almost two years now and is going to give it's review
Talking about the moat importatnt thing .* the network
It gives reasonable range of notwork over different places but is not enough to place calls and use internet in outdoors . although the plans are cheap you may have hot the point why plans are cheap .
Talking about customer service they give good service , but it mostly depwnds on the luck of a person whether he will be treated wisely or not . but it's reasonable depending about how cheap it is !
And the second moat important thing for the end users is there charges and billing . you al must have heared that reliance hobes bery cheap offers which seems so attractive but when you will use the operator you will get an idea of what happens behing the scenes . so be wise and search first on the internet about anything you are hoing to buy as money matters !
Thank you
