I purchase the reliance sim a month ago but the service provided by the reliance sim was so bad that it force me to change the sim within two days.According to me reliance is one of the worst company in the telecom industry it provides you the most poorest service. other than urban if you go in some rural or hilly areas it becomes very difficult to even to make a missedcall. the maximum downloading speed provided by the reliance sim was just 8 to 14 kb/s which was very low as compare to the internet speed provided by other service provider. at last I highly recommend you not to buy the sim of reliance.
