New bb connections comes with a portal id. But how do old users get it?
Having portal id prevents to connect to the internet from any phone
different from the original applier. Right ??

no!portal ID is only given to new users because they login into a new site different from old users to check usage.portal ID doesn't prevent someone to connect to broadband net from other line/phone using your account.this is called port binding & it depends on local exchange not portal ID.

So can someone use any account to connect from any phone as it use to happen ??? Does it still happen ?

This does not (and cannot) happen where port binding is in place.

so does that means i cannot acess new portal whre night wsage might be excluded
old portal lacks this feature but as i have heard it's in the new portal

How do I do port binding ??

is that activated automaticaly ?

port binding is done by bsnl local exchange.for getting your connection port binded contact local exchange.only they can tell if it's possible or not.

Thanks for the help whitestar_999.

One last thing Port Binding is free right ??

yes!port binding is a security measure taken by bsnl to protect its customers from account hacking therefore it is free.
