I am from Kolkata and Airtel has 4G service in Kolkata. But I need to know about the 4G service of Airtel. Does they provide good speed as promised? Also how is their after sales service?
Will it be good to shift form Reliance 3G to Airtel 4G? Tariff is similar for both.So service is what I am looking for.
