1. A computer-implemented method for managing registration of a user equipment (UE) roaming across different provider networks, the method comprising:
receiving, at a subscriber-management entity (SME) from a first service node within a first provider's network, a location-update message associated with the UE, the location-update message specifying a first International Mobile Subscriber Identity (IMSI);
identifying a second service node within a second provider's network with which the UE has a previous registration, the previous registration made with a second IMSI different from the first IMSI;
querying a subscriber-information database to determine whether a single-domain-registration feature is enabled at the SME for the UE;
in response to determining that the single-domain-registration feature is enabled, sending a location-cancellation message to the second service node to cause the second service node to cancel the previous registration made with the second IMSI of the UE; and
registering the UE at the SME.
