Actually 100GB download quota on 1 mbps line is not bad.Theoretically, a 1 mbps unlimited line can be used to download no more than 300 GB in a month, if the connection is running at full speed 24 hours a day for all 30 days of a week. Since Airtel is counting both download and uploads in 100 GB quota. That is approx 80 GB download and 20 GB upload on torrents. So you will get to use torrents for 6-7 hours a day on an average before the 100 GB quota is exhausted. That is not bad at all.They should look into introducing even cheaper plans like 30 GB download quota at 1 mbps followed by downgrade to 256 kbps unlimited at around Rs. 600 or 700 per month.
