SOURCE: SGH-G800 . What is PUK code?

PUK:

The Personal Unblocking Key (PUK) is a code that is required to unblock your phone when you have entered the incorrect PIN ten times (or three times depending on the manufacturer of the phone)

it is an added layer of security for your phone in case somebody tries to fiddle with it and change anything on it.

SOURCE: can't remember phone lock code

Puk code is needed when you have entered the pin code wrong 3 times.

If you have a phone lock code on it and you can't remember to code try the defaults 0000 1234 12345 00000 etc. if you can't unlock it contact your dealer with proof or pruchase or contact a samsung service center, you can get those details from www.samsung.com you will most likely have to send the phone to be unlocked.

you can try entering these two codes without a sim card in the phone. write them where you would write 911 phone should restart. then insert the sim card and try turning the phone on.

*2767*3855# = Full Reset
*2767*2878# = Custom Reset

If these don't help then contact samsung for unlock service you will most likely have to send the phone to a service center.

SOURCE: tocco lite phone freeze deactivate fail

here is some info on PUK codes:

try taking battery and SIM out waiting 15 seconds and powering cell back on.

In your case I believe your SIM is now FROZEN or locked. You mostlikely will need to purchase a new SIM card.

A PUK code (Pin Unlock Key) is required when you enter an incorrect PIN 3 times. After entering the wrong PIN 3 times, the card will be locked and you will need to get a PUK code from your service provider to unlock it.

If the wrong PUK code is entered ten times in a row, the SIM card becomes invalid and you will need to purchase a new SIM Card. The phone will display "PUK blocked call operator".

It's asking for a puk code and i have no idea what to do


Dear Rockerman07:
A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from AT&T to unlock your SIM card.

You can obtain your phone's PUK code from AT&T in one of these ways:

To get your phone's PUK code online:
  1. Log in to myAT&T.
  2. From the myAT&T tab at the top of the page, hover over the Wireless link and select Phone/Device under the My Wireless Service heading.
  3. From the My Phone/Device screen, select the Unblock SIM Card link under the My Make & Model heading.
  4. The Unblock SIM screen will display your PUK code and will give you instructions for unblocking your SIM Card.

Once you receive your PUK code, you will need to enter it into your phone to set a new PIN code

Thank You Margon65

Need code & steps to unblock puc code on cell phone


You need to phone your cell phone service provider for the PUK code. This is because it's the SIM card that locks rather than the phone and the service provider is the only one who can give you the PUK.

Once you've received the PUK you simply try to turn on the cell phone. When it says sim locked you enter the PUK code. This will clear the previous PIN number and you'll be asked to enter the new PIN.

Keep the PUK code safe as it can be used again anytime your phone gets locked.

My access code no longer opens the phone.PUK is requested.What is PUK?


Few people use PIN locking system to lock their phone to avoid un-authorised access. Though this is a good option, it pisses you off sometime. Three wrong entry of PIN code will result in SIM blocking. Once SIM gets blocked, phone starts asking PUK code to enter. If you again enter wrong code for three times, SIM gets completely blocked. You have to walk into your service provider outlet to get a replacement SIM card.
PUK code is a SIM specific code assigned by your service provider. No way you can guess & enter it. So, when it asks for the PUK code, don't do anything, get the PUK code from your service provider. Airtel has a easier way of getting PUK code. For getting PUK code of a Airtel number, send PUKPhoneNumber to toll free number 121. You can make use of any other Airtel number to send this message since your SIM might have been blocked already.
If the above method doesn't works or your service provider is not Airtel, call to customer care using any other mobile phone which uses the same service provider. They will ask some details about you to make sure you are the owner of the SIM card. Questions might include your billing address, email ID, numbers you recently called or messaged etc. They might even ask you number printed on the SIM card, so be prepared with all details before calling them. Once you get the PUK code, enter it into the phone & your phone will return to normal.

As you have entered three wrong codes your phone is locked and now will ask for your PUK code. Three more false trials will result in blocking of SIM card forever.
