Reliance is the worst company compares to the others available in the market. since reliance provide very good data plans and voice plans but due to their bad network coverage they had to suffer. I am also facing the same problem.
low signal quality and poor connection in network. these leads reliance to be a bad mobile operator. also when I call the customer care they did not pick up the call. I had to tried three to four times then they pickup the call. they should look at their customer service and must improve them.
