Why can't Unicom modify the service password?

Modify the password through the 100 10 self-service hotline. If the system judges that the user's password is the initial password, after the system broadcasts the number, it will broadcast a voice: "What you want to modify is the initial password. To ensure the security of your password, the system will send a short message verification code to your mobile phone. Please call again within one hour after hanging up, enter the SMS verification code and modify the initial password. If you can't receive the SMS, please go to the business hall to change your password. "

After receiving the verification code, you need to dial again, enter the correct 4-digit verification code, then enter the initial password, and then enter the new password.

If you feel troublesome, you can reset your password directly and send a short message "MMCZ# plus 6-digit new password" to 100 10 to reset your password. MMcz needs to be capitalized, and the 6-digit password should not be set too simply. After successful reset, please keep the service password properly. You can also log in to the mobile phone business hall or the online business hall www. 100 10.com to reset the service password.

If you can't modify the password through the above channels, you can modify it directly in the local Unicom business hall.
