guys can u help me , i want to know the procedure for changing the BSNL plan. Currently i've "Home 250", & i want to upgrade to "HOME 500".. So How do i change the plan. i tried calling the BSNL Service (1500) , but i couldnt get through. Actually I want to go in for Airtel Broadband, as i'm getting loads of bill (p/m 2000 for net usage in BSNL), but the problem is that i've bought the BSNL Modem, & now i dont want to re- invest again for modem. Can i use Airtel's Broadband with BSNL Modem.
