What should I do if I need to enter my ID card to change my password in telecom broadband, but I am prompted that my ID card is incorrect?

If you try to modify the telecom broadband password and enter the ID number, but the system prompts that the certificate is incorrect, there are two solutions:

1. Confirm the ID number again: Check carefully whether the ID number entered is correct, including the format and the location of each number. The format of the ID number is usually 18 digits, including 17 digits and 1 digit. Make sure all numbers are entered correctly, including a mixture of uppercase and lowercase letters and numbers.

2. Help: If the ID number is confirmed to be correct, but the system still prompts that the ID card is incorrect, it may be a system error or a problem with the telecommunications company. In this case, I suggest you contact the customer service department of the telecom company, explain the problem to them and ask for help. They may need you to provide some additional information to confirm your identity, or they may reset your password.

Finally, if you can't change the password in the above way, you can finally try to click the "Forgot Password" option at the bottom of the password box, and the system will automatically send a random password to your registered mailbox. After logging in with this password, you can change your password again.

Please note that when you change your password, you should ensure the security of your network connection to avoid any potential phishing or identity theft risks.
