One of our customers is an internet service provider who uses SMS for proactive support. The company combines multiple information in the sense of Big Data: Delivery status of the hardware (router), connection appointment of the DSL connection, and the connection’s current status. If the system finds that the router was received, and the connection enabled, but still the client was not connected, the customer receives an SMS offering respective support. The customer then may request further information or a call, by sending a shortcode as response message. The customer satisfaction increases enormously in this case, especially in a highly competitive and notorious market like the DSL sector. Also other markets can use text messages to establish a proactive support communication with their clients. The costs of a SMS are extremely low while the effect on customer satisfaction can be high.
