What should I do if a phone asks for a PUK code?
Answer
The PUK is issued by your carrier, not the phone maker, and only they can give it to you. Find it on the original SIM card holder, in your online account, or by calling them. Do not guess — ten wrong PUK entries destroy the SIM permanently and it must be replaced.
Before you start: stop right away if…
- Ten incorrect PUK entries permanently disable the SIM and it must be replaced by the carrier.
- Only your carrier can supply a PUK. Any website offering to generate one is fraudulent.
Follow these steps
Stop guessing immediately
Do not attempt the PUK unless you are certain. Ten wrong entries permanently disable the SIM.
You should see: No further attempts are used.
Look on the original SIM holder
Find the credit-card-sized plastic the SIM was pressed out of. The PUK is normally printed on it.
You should see: You have the correct eight-digit code.
Check your carrier account
Sign in to the carrier's app or website — many show the PUK under the SIM or line details.
You should see: The PUK is displayed.
Call the carrier if needed
Ring them from another phone with your account details ready. They will verify your identity before giving it.
You should see: They provide the PUK.
Enter it and set a new PIN
Enter the PUK exactly, then choose a new SIM PIN you will remember, or turn the SIM PIN off in settings.
You should see: The SIM unlocks and service returns.

Extra tips
What to look for: The plastic card the SIM was originally attached to — the PUK is usually printed on it. Your carrier's app or website often shows it too.
Before you change anything: Stop entering codes now. The PUK attempt counter is much less forgiving than the PIN one.
