Default MTNL Password?

Hey all..
The installers yesterday didnt give me a username/password..How do I check my usage?
I goto http://register.mtnl.net.in/htmlui_en/index.html and click on register but nothing happens..
So how do i view my usage coz i have no password..i guess the username must be the phone number..

Thanks

the user name is your telephone number and the password is the CA no. (mentioned in ur bill)...use these two...

tell me this, is this link just for MTNL mumbai??? coz i can't login into this... 🤔

in delhi we check our usage from http://register.bol.net.in
