Dear All,
Need guidance from people who have first hand experience of the above mentioned subject.
I will write what information I have and please add to that so it will be useful for others.
1- You bring a mobile phone to Pakistan bought abroad
2- Create a DIRBS account/login
3- Provide your details and enter the IMEI
4- A message will be received saying that as PSID and been created, and you can deposit the X amount in the bank using the PSID (but I doubt that National Bank would receive money without a hard copy of the PSID)
(What are the next steps?)
