I have used reliance post paid sim and that was the worst thing I had ever done in my life.they provide no signal but charge the monthly rental.very poor network coverage.its customer service is the worst customer service.they spoke to me in a harsh manner.i told that I didnt get signal for 2 months but they told its not their mistake but its my mistake.even in a reliance store the staff behaved as if we owe something to them.bloody fellows.nearly I pais 2500 rs without even using its service.its billing and charges are also very high.friends dont use reliance post paid service.its a creepy thing in the whole world.
