The download speed with Airtel 3G varies between 0.43 Mbps and 4.64 Mbps at the same spot at my home!The plans are atrocious, 200/- for 250 MB per month. Airtel does not understand how much data constitutes 250 MB. If the download speed is 4.64 Mbps, it takes a little over 7 minutes to consume 250 MB.98/- 2G data plan offer 2 GB per month. Airtel knows very well that with the speed that they offer (I have not seen more than 0.03 Mbps in Mumbai), people will use less than a quarter of that limit.
