Unicom needs a dynamic password to check the phone bill online. Why can't the mobile phone receive it? How can I cancel the dynamic password check and only use the service password?

If your number is used normally, you can't receive the dynamic password, but it doesn't rule out the interception function. For details, please contact customer service at the place of origin. The dynamic password service cannot be cancelled, but you can log in and query with the service password. If you don't know your service password, you can reset it through the following channels:

1. You can enter the login page of Unicom's online business hall, click Forgot Password and follow the prompts.

2. After entering the login page of the mobile phone business hall, click Forgot Password, enter the mobile phone number and verification code, and then press Next. At this time, your mobile phone will receive a 6-digit SMS password, enter the SMS password, new password, verification code and other information, and then click Next to reset the service password;

3. Send the free SMS instruction "MMCZ#6 new password" to 100 10.

In addition to the above methods, you can also call local 100 10 or go to the local business hall to reset your password.
