Locked out sim card

[paulas]

Galaxy A12- went to put in a pin number for sim card first time, asked for code, tried 0000, 1234.  Now I'm locked out.  Asking for PUK.  Also kept saying "possibly incorrect pin "

Please advise.  Thanks

You can get the SIM PUK by contacting a CS_Agent by chat or private messaging on this Community page.

You might need a PUK for unlocking the Samsung phone. You will need to contact Samsung Canada if your phone was purchased in Canada at 1-800-726-7864.

- SIM network PIN blocked. Enter SIM network PUK." is asking for the phone’s (often Samsung) “master code" after entering the wrong code too many times. Samsung and/or your previous carrier can give you this.

- SIM network unlock PIN" is asking for your previous carrier's unlock code - just contact them with your IMEI (dial *#06# to get it) and they'll give it to you. If you enter this incorrectly too many times, you'll get the error message above.

- PIN unlock key (PUK) is a SIM-specific code used to prevent unauthorised use of a SIM card.

The PIN (Personal Identification Number) enables secure access to the SIM card and network. It is provided with your SIM card.

    If the PIN code is entered incorrectly 3 times, the phone is locked (except for emergency calls) and requires a PUK (Personal Unlock Key) to reactivate it.

Caution! If the PUK is entered incorrectly ten times in a row, the SIM card becomes unusable.
