Lowest cost GSM network provider for STD calling?

[aryan.838]

Actually i am going to move to tamil Nadu while my family lives in UP(E) now I want to buy a new sim which has lowest possible STD tarrifs(On-net). Later on I will ask my family members to switch to that network.
Thanks..

Most service providers have some STD rate cutters, u could opt for it.
Like in my case-airtel has a pack for 28 bucks in which all std calls are charged at 40p/m, valid for a month. In my experience, it saves a lot..!!!
