I am sharing my personal experience of using reliance sim. Reliance makes fool to people it is providing very poor network.It has worst service I have seen in my life even 3G service is just like 2G as compare to other network in India I have used reliance over one year I was frustrated by its service. Call drop problem happens any time even in urban areas. you will receive messages and promotional call from company side every day. Even you receive same message three or four time in regular intervals of time. It happens daily. Some times If you make call it will tell you that receiver is busy even when receiver is free. Only one thing is good some times it offers good call rate schemes as compare to other networks. I would like to suggest please go for other networks, don’t buy reliance.
