Dear All, I am planning to take a BSNL 3G SIM card and use a USB HSDPA Modem for Internet.At present unlimited 3G is very expensive so can I migrate the 3G plan to 2G and get about 1Mbps speed in unlimited plan.I have tried GPRS (2G) in HSDPA Modem but the speed is not that great. I stay in Central Kolkata (Pin 700 012) West Bengal - Is the migration from 3G to 2G possible and how ? I have seen users getting great speeds after conversion of 3G plan to 2G. Kindly guide and help.Thanks.
