These days we have a Personal Identification Number (PIN) for this, a PIN for that, a PIN for everything, including your mobile phone. How on earth do we all keep up with our PINs? Well as it turns out at times we don’t.

Just recently I took a flight from Adelaide and being the good passenger that I am, I turned my mobile phone off as instructed.

Enter-PIN--blog-contentUpon return to Melbourne I fired the phone back on only to have to enter my PIN to activate the SIM card.

“Oh that’s easy” I say to myself and enter 1234 & OK.

My phone beeps and pops up with “incorrect PIN, you have 2 more attempts”.

I re-enter 1234 & OK. BEEP, “incorrect PIN, you have 1 more attempt”.

I am certain this is my PIN and yet according to my phone it clearly is not.

Ok I will try another and after thinking long and hard I enter a different one and this time it’s a triple BEEP BEEP BEEP and the phone displays “ENTER YOUR PUK CODE”.

All of a sudden a wave of panic rushes from the top of my head to the tips of my toes, I’ve PUK’d my phone.

I don’t know my PUK code, what is a PUK code? Where do I get my PUK from? What do I do?

Panic panic panic.

As it turns out, retrieving a PUK code it is a very simple process. No need for panic.

Firstly, what is a PUK code and why does my mobile device have one?Enter-PUK-blog-content

Your Personal Unlocking Key (PUK) code is an 8 digit number that is unique to your SIM card to reset your PIN and unlock your mobile. It is incorporated into your SIM to protect any unwanted usage of your device. After the third failed attempt the SIM senses the wrong person is attempting to access the phone and will display ENTER YOUR PUK CODE.

WARNING : if you continue to enter an incorrect PIN once your phone requests the PUK, the SIM will self destruct, and you will have to replace it. Charges may apply.
