I m using vodafone operator for 2 years.network coverage is awesome_ even in villages only vodafone is a operator that give coverage.but the problems is that the network seems to be temporary busy or the cell phone show no network .and thats the thing that irritate the most .its customer care service is good not so bad.its 2g nd 3g recharges are costly.but speed is superb.but the only problem is its network.soo plzz improve ur network quality and coverage area .
