Unicom sent me a short message saying that my initial service password is the last 6 digits of my card number! Is my card number my mobile phone number?

The initial password is the last 6 digits of the mobile phone number. If it is not changed, the initial password cannot be used for any business operation and needs to be modified.

You can modify the service password in the following ways:

1. You can log in to the online business hall/homepage and click Self-Service > Handling Business > Service Password Management.

& gt If you modify the service password, you can modify the password;

2. after logging in to the mobile phone business hall client, click handle > business handle.

& gt service password modification: enter the original service password and the new service password to modify the password;

3. Send the text message "40 1" or "MMXG# old password # new password # new password" to 100 10 for free to change the secret service password.
