Wireless internet services billing enables a telecommunications company to bill internet service events on a transaction level. In a described implementation, an internet service event, which occurs at least partially within an internet environment, is detected. An internet services proxy injects event billing information related to the detached event into an event billing information communication that is sent to a telecommunications billing gateway. At the telecommunications billing gateway, the event billing information is logged into an event billing log in association with an identity of a telecommunications user. By way of example, the event billing information may comprise an action indicator and an entity identifier. The action indicator indicates an action corresponding to the event, and the entity identifier identifies an entity that is associated with the event. The internet services proxy may be located at a telecommunications device of a user, at a provider of internet services, or both.
