Simply write your CNIC (without dashes) and send it to 668

For instance
Write 3749127299334 and send it to 668.
You will get a reply with number of connections issued against this CNIC for 6 companies (Mobilink, Warid, Zong, Telenor, SCO and Ufone).
Service won’t tell you cell numbers, instead it will actually tell you amount of numbers – for instance, Mobilink 3,
Ufone 3,
Telenor 2,
SCO 0,
Warid 0
Total 8.
Charges
Rs 2 plus Tax per SMS, however, charges may differ at the time of launch. Let us know the results in comments.
Indeed a great service.
By the way, as mentioned above, service is not publicly available – but we, here at ProPakistani, strive to bring you things before they happen.

Update: Few readers have reported that service is down – maybe it is pulled back by operators, or the data server is down/under maintenance. Let’s wait and try again -do share results in comments.
