SOR – Support of Optimal Routing

SOR (Support of Optimal Routing) is a network feature which enables the calls directed to a mobile subscriber to be routed directly to the mobile subscriber’s actual location, or to their forwarded to destination (instead of via the HPLMN (Home Public Land Mobile Network) or in the case of Late Call Forwarding via the VPLMN (Visited Public Land Mobile Network)).
