Management of native subscriber registrations on a foreign network is accomplished via an approach that advantageously offers dynamic roaming, that is, the capability to send data over-the-air to populate a customer subscriber identity module (SIM) card with specific networks, in a specific order of preference, according to the characteristics and capabilities of the subscriber mobile station, the subscriber's home network, the foreign territory roamed, and the like. The approach also provides an SS7 service-based solution including the capability of the home network to control the roaming mobile station from registering on a non-preferred visited network, based on configurable rules. The approach provides the ability to segment subscribers, increased/assured quality of service, no limits on designation of carrier preferences, the ability to apportion roaming traffic across numerous operators in a given foreign territory, capability for real-time changes of preferred network, and preservation of manual network selection capabilities.
