Methods and systems for associating a mobile station subscriber with at least one application or service are provided. The subscriber is provided with a subscriber identity module (“SIM”) identifier, which identities a SIM associated with the subscriber. The SIM identifier is bound to the application or service. The SIM identifier and the application or service are registered with a home location register (“HLR”) to bind the SIM identifier to the application or service. If the SIM is a virtual SIM, the provider of an application or service may cover the data costs associated with the use of that application or service.
