Simple. Your friend should contact his or her Service Provider. BTY, this is the ONLY place you can get a Personal Unblocking Key. Guessing will result in your friend's phone being damaged. There is a short article at Wikipedia you should read. Find it here:

I need the puk code for the ga837


The phone is not what is blocked it is the sim that is blocked. When the phone is blocked, it asks for security code, but when your sim card is blocked, it asks for the PUK code to unblock it so as for you to be able to access both the phone and the sims services with the sim in it.

The PUK code means personal unblocking key, and it can be found at the back of the pack where you took your sim from, or on the card whick you borke out the sim card from. It mostly used to be 8 digits.

If you do not have the pack anymore. contact the help center of the sim service provider and they will give it to you.

Thank you for using fixya.

NOTE: If you insert another sim into the phone that is not blocked, the enter PUK number will not longer be on the screen, you can try a friends sim to confirm this. Once that is done, you will now know that the problem is from the sim, not the phone.

My sim card is blocked wondered how i can unblock them

You need a PUK ( Pin Unblocking Key) code to be able to unblock the counter of you PIN ( Personal Identification Number ) . The code can be found enclose on your sim package .If its not in their,then you have to call your service provider operator and request for that code,or you can go directly in their wireless center for fast approval.

When you already receive the code, just enter it on your mobile that ask for a PUK code,after unlocking it,enter a new PIN code and it will ask to re-enter it again for sure you encode the exact numbers to avoid errors.

Now enjoy using your mobile....

SAMSUNG SGH-E250 puk blocked

Hi everyone

Every PUK code is unique so nobody can tell you your PUK number, but i will tell you what you can do!
1) If you still have your packet that your Sim Card came in, you should find your PUK number in there, if you don't have the packet, please read bellow.

2) You must get a phone that is on the same network as your phone and call the networks Customer Care and ask them for your PUK number, they will ask you for your phone number, then they will tell you your PUK number. Once you have done this, you will be able to reset your Pin number so you will be able to go into your phone again.

Please also remember to give me a good rating on my profile.

Kind regards

Can you please provide me with the PUK code for my phone please?

Complete information :
The SIM card protects your subscription and not the phone from unauthorised users. If you change SIM cards you can still use your phone with a new SIM card. Most SIM cards are blocked at the time of purchase. If your SIM card lock is on you have to enter your PIN (Personal Identity Card) every time you turn on the phone.

If you enter the wrong password three times in a row the SIM card gets blocked. This is indicated by the message PIN Blocked To unblock this you need to enter your PUK


card (Personal Unblocking Key). Your PIN and PUK is supplied by your service provider. You can edit your PIN and select a new four to eight digit number
  • If the Message Codes do not match appears when you edit your PIN you entered the new PIN incorrectly.
  • If the message Wrong PIN followed by Old PIN appears then it means that you have entered the old PIN incorrectly.

To unblock your SIM card:
  1. When PIN Blocked appears enter your PUK > OK
  2. Enter a new four to eight PIN > OK
  3. Re-enter the new PIN to confirm > OK

To edit your PIN:
  1. > Settings > the General tab > Security > Locks > SIM Protection > Change PIN
  2. Enter your PIN > OK
  3. Enter a new four to eight digit PIN to confirm > OK

To turn the SIM card On /Off
  1. > Settings > the General tab > Security > Locks > SIM Protection > Protection and select On or Off
  2. Enter your PIN > OK
