What is the mobile phone card of Telecom?

The "mobile phone business card" service means that during the call between the calling and called users, the system automatically pushes the preset business card information to the other party's mobile phone through SMS, and the other party can see the business card information after the call. It is a value-added service that transmits additional information during the user's call. For more service benefits, click "official website" customer service 397 below to answer your questions.
