Send a private message to moderator to get the puk code. Moderator wait time is 3 days.
@TaraBenoitWhile you wait for your PUK code which can take days, @cappaj provided some good info he learned on his S7 where sometimes when someone requests a puk code, it was actually not what they needed.
"SIM network PIN blocked. Enter SIM network PUK."
- This is asking for Samsung's "master code" - I got this after entering the wrong code for the message below too many times. Samsung and/or your previous carrier can give you this.
"SIM network unlock PIN"
- This is asking for your previous carrier's unlock code - just contact them with your IMEI and they'll give it to you easy peasy. 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.
Caution! If the PUK is entered incorrectly up to ten times in a row, the SIM card becomes unusable.
As stated above, if you have a Samsung phone, you can try to contact Samsung directly either via live chat or phone to get PUK code. Faster than waiting for moderator help. Even though Samsung phone are sold unlock, sometimes they lock to the first carrier.
If you have another brand, you will need to wait for moderator help.
