I am using Reliance 899 jalsa plan for unlimitted with 50% discount it means my monthly bill is 570/- per month including serivce tax. It has unlimitted local and std in any circle unlimitted 2G internet 100 SMS per day and unlimitted 2 way roaming. This is one of the plan which I am looking since long time. Very useful, there is no hidden charges. But sometime it has network issue. That is also because of weather, that why I have given 4 star rating other wise 5 star.
I suggest in budget this is best plan.
