I would really not recommend you to purchase reliance Sim card.It is one of the worst mobile service provider of our country.Network coverage is very poor.Internet speed is slow as like snail.T he customer care center are not much good as other companies.I face many problem in my connection and the services they provide are very poor.Poor sound quality within the calls sometimes call dropping problem also occurs.I would recommend you to get other Mobile services providers like Airtel, Idea and many others.
