Well I have been used bsnl postpaid card since last 3 yers aprox. Yep there are saveral problems in the services but there are also saveral good features exist. One of the good feature is it provides 3g data service in lower prize I mean no network has this kind of prize rate also if you have some data balance in your account and still you recharge some more balance then it will adds up with old data so here is no reduption of data seen. Bad thing is it should provide good network coverage as it is our gov. Comp. So it should have some standard things. Also they have to provide lifetime or 20 years validity as the card comes with the validity of 6 months periods
So finally good for the internet otherwise its okey.
