Unblock your SIM with a PUK code

Your phone can become blocked if you enter the wrong SIM card pin number three times in a row. If this happens you won’t be able to make and receive calls or texts. To unblock your SIM, you will need a PUK (Personal Unblocking Key) code. You can find this on the My Account portal.


Click the Asset Management menu option and then Mobile Management. The page displays all your live mobile services. Find the mobile number you need a PUK code for and tick the box to select it.



Select the Unlock SIM action from Select Actions then click Apply.


The PUK code will be displayed on the screen.
