In daily life, we often encounter the situation that the SIM card of the mobile phone is locked. This happens that often leaves us feeling confused and helpless, especially when we need to use our phones urgently. In order to help you solve this problem, this article will introduce two mobile phone SIM unlock methods in detail to help you unlock the locked state of your SIM card smoothly.
1. Check the PUK code through the mobile phone card to unlock.
Find the SIM card: First, we need to find the SIM card that is currently in use. In addition to the mobile phone number and password, this mobile phone card also has a PUK code. This PUK code is specifically used to unlock the SIM card that is locked.
Scratch the PUK code: On the back of the SIM card, there is a barcode with a PUK code. This barcode is covered in a thin film, and we need to scratch it open in order to see the numbers underneath. These numbers are the passwords that we are going to use to unlock the SIM card next.
Enter the PUK code: Once we have the PUK code, we can unlock it. We can borrow a friend's phone and call the mobile operator's service**. Press the corresponding keys in turn according to the prompt until the system prompts us to enter the PUK code appears. Then, we enter the PUK number we just found and press the number key to confirm.
System validation: After entering the PUK code, the system verifies that the password we have entered is correct. If the password is correct, the system will inform us that the PUK code verification is successful and will show that the SIM card has been unlocked. If it is incorrect, we will be prompted to re-enter. If you make a mistake more than ten times, then the SIM card will be permanently locked and can no longer be used.
2. Unlock by logging in to the mobile ** to query the PUK code.
Sign in to mobile: Another way is to sign in directly to your mobile operator. First of all, we need to enter our mobile phone number and password for the service. Then, go to the "Online Business Hall" page.

Check the PUK code: After entering the corresponding information, our PUK code will be displayed. This PUK code is likewise an 8-digit password that is used to unlock our SIM card.
Record and unlock: After querying the PUK code, we need to write it down. Then, follow the previous steps and enter this PUK code into the corresponding location of the phone, and the SIM card unlocking can be completed.
