I was changing my sim code when i realised -too late- that i had entered the wrong sim code to actually put in my pin code.. now its in puk can u please tell me what the puk code is for optus nokia

With your sim came a pin code (you could change that) and a PUK. After you entered a wrong pin in 3 times, the phone is locked. You than use the PUK to reset the PIN.
The puk cam on the came card or paper you initial pin came. (often the card you broke out the SIM)
When you can't find the PUK, ask your provider. And if he can't give a PIK, ask for a new sim they should put your phone on the new sim. Then you have a new pin and a new PUK. Keep the PUK on a safe place, so you don't need the help from your provider next time the pin is entered wrong.

its Personal Unlock KEY..........for phone security......actually before PUK u enter sim pin........if wrong pin is entered 5/10 times your sim is locked permanently and sim can only be used after u enter puk code. Please note that pin code is entered by user.....but PUK code is provided by your network service provider company. PUK is generally mentioned on the sim rapper(cover).........in case u have not kept the rapper and u do not know the PUK code and ur phone is asking for it...then please do not try to enter it as too many attempts to enter wrong PUK will lock ur sim for ever and u will have to get a new sim.....so instead of trying a wrong PUK code its better to contact your network service provider (you can call their service number) and he will give u the PUK code for your sim free of cost.
I Hope this clears all your doubts about PUK.

PUK stands for Personal Unblocking Key. This is a uniqueeight-digit code specific to your SIM card. This is required when the PINnumber to unlock your mobile phone is entered incorrectly 3 times. You are thengiven 10 attempts to enter your PUK code. If an incorrect PUK code is enteredafter the 10th attempt, you will block your SIM card permanently and willrequire a new SIM card from your mobile phone provider.
PUK codes can be obtained through the following ways - The PUK code is in your SIM card documentation Starter Pack.If you do not have this then -Please contact your phone service provider.
Your cell phone service provider can give you the PUK code once you give themyour account details and they have confirmed your identity.

if its troubling u abt pin code and if u dont remember it, then u've a very simple procedure.
Read this section & u'll surely be able to enter a new pin code.

Enter Pin code of ur wish, u just need to block the sim so that ur phone asks u PUK code.
i guess pin code tries are abt 5-7 times.
So it will say Sim card Blocked Enter PUK code.
Now call to customer care from other number of same newtork provider & ask then ur PUK code.
they will ask u a 16 digit code, which is printed on ur sim card. after u provide 16 digit code to customer code, they will provide u ur PUK code,
Enter the PUK code given & now enter ur New pin code.
This is quite lenghty process but 110% working.
If u like my post, please rate me up, i really need some good ratings..
Thanks.

you have entered the pin code wrong 3 times now you are required to enter a puk code to reset the pin code. 

The puk code is sim card spesific it comes with the sim card when you get it or you can get it by calling your phone service provider of the sim card to get the puk code. 


if you have entered the puk code wrong too many times you will make the sim card useless and you will have to contact your phone service provider for a new sim card, it will probably cost.

samsung phone "PUK blocked Call SOS" - i have the PUK code but cant put it in as its not giving me any option other than call sos. how do i put the code in to unlock it.

if you enter the wrong pin code for 3 times your sim will get blocked ...
it will ask for the puk code ...
then you must call to the customer care of your network provider and you must tell them that your pin got blocked you want the puk code ...
they may ask for the details of your sim card be sure to tell it ..

then they will provide the puk code note it down and enter into it ..
your sim will get unlocked...

note :
if you enter the wrong puk code for more than 3 or 10 times the sim will get fully blocked if then you must contact to network provider shoppe....

puk number is given by the network provider ....

i think you blocked the pin code by entering the wrong pin code for 3 times so it is asking for the puk code ..

to get puk code you must follow these steps :

1. call to your network provider customer care

2. tell them that your pin code got blocked you want puk code

3. if they ask any details about the sim card owner you answer that one ...

4. then make a note of the puk code and enter in to your cell

note :
if you enter the wrong puk code for more than 3 or 10 times your sim will get fully blocked you must purchase the duplicate sim card or you must contact the network provider shoppe ...

A PUK CODE SHOULD BE CALLING YOUR MOBILE PROVIDER FOR THAT...OR THE SIM-CARD ENVELOPE, SHOULD HAVE THAT PUK CODE IN THERE
