What Does ‘Enter PUK Code’ Mean And Why Did The Sim Get PUK Blocked On Samsung Galaxy F04 Device

If your SIM card is disabled, you probably entered the incorrect PIN code too frequently. Your SIM locks itself after three to five wrong inputs, on average. Although it might be annoying, doing these guards against unauthorized access to your phone and personal data. If your cell phone is lost or stolen, PUK blocked will prevent prospective hackers from making calls.

Your mobile phone display can say “PIN blocked” or “Enter PUK code.” PUK stands for PIN Unblocking Key in the PUK code. The PUK code is seldom given to you when you receive your membership in the US. Contact Your Samsung Galaxy F04 provider’s customer support if you don’t know your PUK code.

Part 1: Why Was My Sim Card Blocked?

1. 3 times incorrect Pin entered

Sometimes when you forget your pin and keep on entering the wrong one, you can get PUK Blocked. You can utilize three to five chances, and your sim gets blocked when you enter the incorrect pin in all of these attempts.

2. Wrong PUK code entered

Sims are frequently blocked; therefore, if you have your PUK, keep it in a secure location separate from your phone. This is because it is the key to unlocking your SIM. The SIM will be permanently disabled, and you will have to buy a new SIM card if you input the wrong PUK ten times in a row.

Part 2: What To Do When I Blocked My Sim Card?

Your SIM card has been disabled to protect your security if you enter three wrong PINs and your phone shows “SIM card banned” or “Enter PUK code”.

You must input a PUK (PIN Unlock Key) code to unlock your SIM card.

Go to your phone’s settings to customize your PIN code after using a PUK code to unlock your SIM card. Pick a PIN that is simple to remember.

If your PUK code was delivered to you by email:

You got an email with multiple codes, including PUK1, PIN2, and PUK2.

If your PIN is locked, use PUK1 to unlock it.

Only a few phones employ PIN2 and PUK2 codes to restrict access to certain SIM card functionalities.

PIN2: The default code for your SIM card; If this code has been altered, use the PUK2 code to restore it.

PUK2: Your PIN2’s unlock code if it has been blocked.

Part 3: How Can I Have My PUK Code To Unlock Sim Card?

1. Get it from sim card packaging

The packing box is the best and easiest place to look for the PUK code to unlock your SIM card.

You probably have memories of the flat plastic package you got when you bought a SIM card. Your PUK and default SIM pin code should be written on the package.

Please look around your home for the package and look on the back for the key. On some older packaging, it could be sealed behind a scratchable region, whereas on other, more recent ones, you might find it unsealed.

In either case, the correct PUK has 8 numbers and should be simple to enter to unlock your SIM card.

2. Have it from carrier website

In all honesty, I doubt I’ll ever be able to locate my SIM card package again, and I imagine most people feel the same way.

But happily, a lot of cell companies let you access your account on their app or website to check your SIM card PUK. Please log in to the appropriate website or app, then go to your profile to see whether anything about “PUK” is available there.

It shouldn’t be an issue if you were utilizing or signed in to the platform before your SIM was disabled. However, if not, you might not be able to access anything since you could be asked to input an OTP to verify your identity.

Please remove the SIM card and try again if you can’t access your phone to utilize the app or website because of the SIM lock. After receiving the PUK code, you can re-insert the SIM and input it.

3. Contact your carrier

It’s time to call customer support, which should be simpler for most individuals if none of the above options work for you. For example, your mobile service provider created your SIM card. Therefore, they have all the information you would require. Before they divulge anything to you, though, they should be able to verify your identity.

Use a different phone to call your customer service number and describe the issue. And following a series of inquiries, they should offer your PUK number as identification.

However, customer service won’t release the code if you can’t back yourself up. And at that point, there’s probably nothing further you can do. Therefore, make sure you have some information, such as your name, address, date of birth, etc., before you call them.
