i have bbg 500 fn plan currently. i want to change it to an unlimited plan with good speed. currently i am getting upto 2 mbps (200 kbps) for torrents and IDM. i checked the available plans with bsnl site. but all are giving low speeds. also i have to be careful while changing plan coz the current plan is discontinued and if change to some other plan, i will not be able to revert back. pls help.
