Technical Contextual Intelligence
Steering of Roaming (SoR) allows an operator to prioritize specific roaming partners. This is usually driven by inter-operator discounts (IOD) or specific Quality of Service (QoS) guarantees in the visited country.
Signaling Steering: Relies on the HPMN intercepting Location Update (MAP/Diameter) requests and rejecting them until the handset attempts a different available network.
Over-The-Air (OTA) steering involves updating the EF_PLMNwAcT (User Controlled PLMN selector with Access Technology) on the USIM via secured SMS-PP.
