A call pattern associated with a telephone number of a subscriber of a wireless carrier network is monitored. The call pattern is then analyzed via a machine-learning algorithm to classify the subscriber into a subscriber classification category of multiple subscriber classification categories. A determination is made as to whether the subscriber classification category of the subscriber corresponds to a service plan type of a specific wireless service plan subscribed to by the subscriber for the telephone number. When the subscriber classification category fails to correspond to the plan type, an offer of an additional wireless service plan that corresponds to the subscriber classification category of the subscriber is sent to a user device of the subscriber. When the subscriber classification category corresponds to the service plan type, a caller category label is assigned to the subscriber that indicates the subscriber classification category of the subscriber.
