If you make a lot of phone calls while on the road.
Then Vodafone is the best mobile operator for you in Delhi, according to the results of a two-day ‘drive test’ conducted by quality auditing firm TUV SUD on behalf of the Telecom Regulatory Authority of India.
The drive test, which involved making around 450 calls per operator while driving over a distance of 300 km, also showed that Reliance GSM scored very poorly in terms of network quality.
Bharti Airtel, the market leader in Delhi, seemed to be struggling more with quality issues compared to rival Vodafone.
