Since Nov 30 Airtel speeds have come down a bit in 2G and a lot less in 3G. There are people using 3G pack and getting low speeds too unlike 3-6 mbps previously.If you use a 2G pack, do not try to connect in Dual or 3G. It will show connected in 3G but give you only 40 kbps.Force it connect in Edge only, it will give 120-160 kbps atleast.3G speeds in 2G packs is almost already history.
