I have been using Reliance prepaid sim for last 3 years. here are better low call rates options. but its network is not as good as earlier. I was also having a postpaid connection too, whose network was good. internet browsing is also not good enough.
Earlier I had to loose money without getting any talk value. after seeing a scheme of Rs. 31. I recharge 3 times but each time I get nothing neither my payment was paid back in any form. when talk to customer care, it was not available for two days consecutively. They denied of such plan and also returning my money back.
