Enter the random code received by the mobile phone, and the new password will be sent to the mobile phone by SMS. You can choose whether to change the password according to your needs. If you don't have a mobile phone card, you need to go to the business hall if you forget your password. With the phone number of the SIM card, you can provide information such as payment vouchers or network access documents for nearly 3 months to reset the password. The service password is your identification password. With the service password, you can obtain corresponding services or products through various channels of China Mobile.
