I am a fan of idea now, why because I had been going through nightmares from last 2 years with airtel and voda as there service was pathetic and disgusting .
As I am from delhi 3G works here as a charm and also in cyber city gurgaon . The best crisp network specially 3G and the best so far .
although JIO still Champion .
One suggestion to all operators why dont you guarantee QOS as a prime prospective as there should be atleast an upper limit or an lower limit defined for internet speed, it shouldnt be going that much down .
well still I am not sure how much time this actually works but yes Idea is the best for Paschim Vihar area, even better speeds than 4G . I am in love with this impecabble data offer 6GB for 97 . Go for it .
