If you are planning to go mobile just try it.Currently BSNL is offering two type of connections. Excel for prepaid and CellOne for postpaid.I just change my service from Reliance to BSNL and just beleive it I just save 40% in first month.Billig system is fine you can receive your billing information round the clock.SMS is free in prepaid connection , zonal roaming is free in prepaid connection .National roaming is free in postpaid connection.It works all national highways and even in small town.You can download ringtones, picture message and operator logo through their service.So why you are waiting for TV.come mobile phone :)I think you are understand..no faida there.. Rs.20, 000 is not a matter of joke and there is no roaming..You can go cellular with BSNL for just Rs.2500 ( Rs.2300 for handset and 200 for connection).So go for BSNL CellOne.
