How to look up username and password in modem

How can i know what password and username is being use in modem net connection settings ?

(i am not asking about Modem page Login)

username is your phone number i.e 375*****

Password is 1234

7 digits or is it 8 digits?

In Lahore it is 8-digits.

mine is like this 4 digit city code and 6 digit number than what it would be like ?

instead of phone number i have my own name as my username...

how did you changed it ?

i didn't change... thats wht i was allotted by PTCL

can i ask to ptcl for my username and pass code?

sure u can

BUT they said you have to provide us your civil ID card number first? WTF :(

don't u have NIC?
