After many trials with different service provider( tata indicom, reliance net connect, tikona wi bro in kharghar Navi Mumbai. One can read my review). I finally settled down for mtnl triband and fact is that I never got to call up customer care or service center for any complain, im fully satisfied with the speed and price they charge.one thing is that they only fix the connection once you have a land line connection, waiting period for wi fi instrument is about 25 days. Better you buy your own instrument. Connection is done in 2 days time,
Enjoy MTNL triband.
