What is how to unlock sim card without puk code?

It is generally impossible to unlock a SIM card without a PUK code if you've entered the wrong PIN too many times. The PUK (Personal Unblocking Key) is a security measure implemented by mobile network operators to prevent unauthorized access to your SIM card.

• Contact Your Mobile Carrier: The only reliable way to get a PUK code is by contacting your mobile carrier. They will verify your identity and provide you with the correct PUK code. Be prepared to answer security questions related to your account.

• Online Account (If Applicable): Some carriers allow you to retrieve your PUK code by logging into your account on their website or mobile app. Check if your carrier offers this option.

• SIM Card Packaging: In rare cases, the PUK code might be printed on the original packaging of your SIM card. Search for it there.

Important Notes:

• Entering the Wrong PUK Code: Entering the wrong PUK code too many times (usually 10 attempts) will permanently block your SIM card. You will then need to get a new SIM card from your carrier.
• Third-Party Software/Websites: Be extremely cautious of any third-party software or websites claiming to unlock your SIM card without a PUK code. These are often scams or could contain malware.
• Data Loss: Unlocking a SIM card with a PUK code doesn't erase data from your phone's internal storage or SD card. It only unlocks the SIM card itself.

In conclusion, you need a PUK code from your mobile carrier to unlock a blocked SIM card. There's no legitimate workaround.
