I use Unicom 3G card. Today, I accidentally opened the mobile phone business hall in the USIM card application, and it automatically sent a short message, and then prompted that the registration was successful. When using the USIM application in the mobile phone for the first time, you need to verify and register the Unicom mobile phone card. This is verified by the system automatically sending SMS, and there will be no charge. It is normal, so don't worry.

Mobile phone USIM card application center is a menu tool for mobile phone quick query, which can be used for quick query.
