I buy reliance sim because they provide services at a cheaper rate and when I used it I find that yes it is true they provide me call rate at 40 p/ m and 250 mb 3g for every month upto 6 months as iam a studend it very good for me and after 6 months call rate is 72 p/m and provide me a lot of tariff to decrease my call rate and their internet service is awesome they lrovide internet at avery low cost that is one gb cost rs 9 only for one day and provide awesome packs every months and last month I got unlimited 3g for a whole month in just rs 447 only .but last week they deduce my 250 Rs and my unlimited net pack without any region and I am not even able to call customer care because no nody is responding from that side . so think before use reliance
