If your number is post paid then you can get the details for warid web page by registering yourself there but if it is Pre-Paid then forget it.
Tell me something, do you want this for a particular time period or what? If you can give me some time lines I can get you all the details from any Operator in Pakistan and I hope that is this not some bloody setup or something.
People give excuses like these to check the details and later something else turns up. So one has to be very careful with things like this.
By the way no embassy ask you for your call details as why would they be interested in your calling details. If they are that much curious then they can get all the details for anyone but you.
Anyways satisfy me first and give me some solid reason for doing this, I might help agar Baath Apni Samajah Main Aa Kaey tou.
