Jilin Changchun Unicom mobile phone opening call signature

Hello, "call signature" is a value-added service that transmits additional information during the user's call. During the call, the system automatically pushes preset mobile phone signature information (mood, jokes, business information, etc.). ) to the calling party's mobile phone in the form of text, so that the other user can see the mobile phone signature information during the call, so as to achieve the purposes of showing personality, sharing feelings and transmitting business information. As this business is independently formulated by branches in various provinces and cities, and the whole country is not uniform, I suggest you call 100 10 for customer service consultation.
