Mr.Ashutosh, please remember that MTNL and BSNL are still offering cheap services and also in rural areas where private operators do not go. also note the exorbitant and excess billing resorted and complaints from public in courts on PVT telecom operators. My experience with them is worst. They charge for calls not made and claim it as data usage though no usage take place. I have filed a case against Reliance Mobile in court now
