Bharti telecom or simply airtel evolved too much in few years and the reason is goodgood network coverage, good speed and decent customer.But as they evolved they raised their service prices just like a actor/actress do after a Blockbuster movie. They need to provide their service at low cost. There was a time when they provided all services at low cost as compared to other operators, I think now they are focusing more and more on ads making false claims about 4g network coverage. Here in my my village we got airtel 3g network coverage before three months??
