The mobile phone card is locked, so I can't send short messages. How to break it?

The main reason why the SIM card is locked is that the PIN password is entered more than three times and is incorrect, and the SIM card will automatically lock. At this point, if you know the PUK password, you can enter it and unlock the SIM card after it is correct.

Method 2: Unlock the password with software.

If you don't know or forget the PUK password, you can use your mobile phone to unlock the software of the SIM card, but the software needs to be downloaded from a professional website, which is difficult to operate.

Method 3: Find mobile phone customer service

If the above methods can't be solved, or you forget the PUK password, you can go to the customer service center of SIM card to unlock it. Usually go to a large business hall.

After giving the SIM card to the customer service staff, the customer service staff will swipe your SIM card and then display the initial PUK password of your SIM card on the computer. After you get the password, enter it in your mobile phone and you can unlock the SIM card.

It should be noted that when purchasing a SIM card, you must mark the PUK password of your card and keep it properly so that the SIM card can be unlocked after being locked in the future.
