The largest mobile operator in India. But Airtel gives worst offers to their customers.
They have good network signals every were but costing too much amount for call charges and data too. and giving fake offers too, recently airtel offered MNP offer but its fake one I changed my network from idea to airtel but they costing too much for calling more than 10 paisa per 1 min airtel to airtel. and other networks too. And Customer support is fine responding in time.
The Charges and billing is high expensive. I never recommend airtel mobile network anymore.
