Question about Samsung SGH-D820 Cellular Phone

1 Answer

Powers off immediately after entring pin code

My samsung D820 is not working. After entering my PIN it accepts it and briefly shows my welcome message and then switches itself off. I've tried changing the battery but the problem seems not to be battery related. What I notice is that when powering it on, I do not need to press and hold the power on button, just a small touch switches the phone on.

Please help !!!!!!!!!

    I have tried to leave the phone off for a while, without the battery, but it still switches off after entering PIN.

    Sometimes it switches off immediately after the PIN and sometimes a few seconds later, after displaying the Welcome Message. If I do not enter PIN, the phone stays on. If there's no SIM card, it displays "insert SIM Card" and does not power off.

    I have tried putting in another SIM card but it did the same thing as well. What I notice is that after removing the battery and SIM last night, following your suggestion, and left it off the whole night, this morning it does not power off but says "Limited Service" and the handset sign is crossed out like I'm not on the network.

    The good thing is that I have been able to download all the information to my PC using the USB cable so my may challenge now is to get back to the network. I will try again later and keep you informed.

    Thanks a million for your help thus far and I strongly believe together we will conquer this one. My main worry was the info on the phone so at least now I'm a step ahead.

    Thanks again and I strongly believe together we will conquer this one.

Did you try leaving the battery out for a few hours so the phone can be reset?

    Does this always happen exactly the same? If you just turn the phone one without punching in the PIN, does the phone stay on?

    Do you have another sim card in which you can try? I suspect that there is something wrong with the sim that is causing the phone to shut down.

Puk code for a nokia6300

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 this solution a FixYa! rating if it helps you.

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
