I stays in Dwarka which is delhi's one of the most famous city. I used vodafone, they really have pathetic and worst network in dwarka. If there is problem in major cities of Delhi so you can imagine how bad vodadone network is there in other rural areas. They called themselves as second largest cellar network in India but believe me its the number one largest worst mobile operator in India. They have decreased there standard, the speed of 4g internet runs like 2g speed. You cannot watch youtube video in dwarka on Vodafone 4g. I dont why there tariff plans are also highly costly if they are not provide full satisfaction to there user then why they have suck hike price ? There plans are highly costly, there surfing and downloading speed is way too low. Now I had port my sim to airtel.
