How to change your PIN via keycode


Your SIM is protected by a PIN. As soon as you turn on your phone you will be asked to enter the PIN you got together with your PUK.

  • Keycode to change your PIN: **04*[previous PIN]*[new PIN]*[new PIN]#

Your SIM will be barred if you fail to enter your PIN correctly after three attempts. You can unblock it by entering your PUK.

How to unblock your SIM:

  • Confirm with “OK” when asked to enter your PUK
  • Confirm with “OK” when asked to enter a new PIN
  • Confirm with “OK” when asked to enter your new PIN again
  • Keycode to unblock your SIM: **05*[puk]*[New PIN]*[New PIN]#

I can not access this part, so I understand I had to have the account here on the site using my mobile number. The problem is that I only came to deal with this after having problems with the pin and needing puk. I tried to register on the site using the mobile number and the site sent a password via sms, but since my phone is blocked I can not see this password and therefore I can not log in to find puk. Do you have any other way to get puk? I am not in Germany and it is likely that I will only come back next year, but I have in my hands the contract with o2 from when I acquired the chip. 😥
