How much does community SMS sending equipment cost and where can I buy location-based SMS equipment?
Community SMS refers to sending messages in specific areas (such as airports, stations, business districts, hotels, conferences) Address, etc.) and a new type of SMS value-added service that provides personalized information services to specific user groups (such as travelers, shoppers, accommodation and dining personnel, conference participants) at specific times. The community that the community SMS refers to is a specific artificially defined area. When a mobile phone user is detected entering the specific area, advertising information related to the location area is sent to the mobile phone user. The purpose is to allow mobile phone users at a predetermined location to obtain advertising information related to and interested in the area at the first time. Merchants set up a series of interactive mechanisms such as text message replies, prize-winning quizzes, and free phone credits to cooperate with user consumption behavior using data mining technology. Through analysis, we can derive more targeted product promotions, ultimately locking in our own user groups, and deliver advertising information quickly and effectively, thereby promoting merchant sales and improving efficiency.
