Excuse me, how to modify the password of mobile phone card through SMS?

Hello, you can't change the password of your mobile phone card by SMS. If you are talking about the PIN code of your mobile phone, you set it yourself at the beginning, and then change it if you want. It doesn't matter if you forget the PIN code. As long as the card sleeve of the mobile phone card is still there, there is a PUK code. After entering the wrong PIN code three times in a row, you will be prompted to enter the PUK code to unlock it. Therefore, if you have the PUK code, you can change the password. If the PUK code is lost, you can also go to China Mobile Business Hall to provide the invoice for your mobile phone card and your ID card, which can help you get it back. If the password you said is the password of the mobile phone service, if you forget it, the way to reset it is to submit the mobile phone card set and ID card to China Mobile Service Hall, and it is best to bring the invoice.
