What must I do to track down a private handphone number?

Question

Recently I have been receiving prank calls from someone. This person's number is a private number. This person call me and say vulgarities. May I know if i should do anything or can I trace the number?

Thank you.

I am using Singtel Service. Singapore

Answer 1

the singtel will trace the number for you, they will charges you, all you need to do is call them, thew will assist you, then pay the bill, that is, alternatively you can call 999.

private number not necessary is a public phone #no, house tel can be registered as private too.

Answer 2

private numbers are from some of those public phones..so it cant be traced bt only by the authorities when they are tracing criminals..

Answer 3

well you can trace it but you have to keep them on the phone for more than 1 minute. i had prank calls once to and we just calle optus (whatever your phone is with) and told the about it and they can then track them down. but its better to call the company your with straight after you get the prank call.
