56561 is right ... DONT TAKE YOUTELECOM (formerly Iqara) ... false charging , always network down , false mb consumption , bad (rather worst) customer service .... rude employees (threw them practically out of my house with the router and their modem) ........ as a simple example after a fresh recharge they charged me "you have used 6750mb" ...... this was in less than 4 hours and my PC was not even switched on !!!
TataIndicom , BSNL seem to be good choices ... although some people also refer to the Airtel broadband .
