Abstract
A method includes receiving, at a network device in a shared network that includes a plurality of PLMNs, a request from an inbound roaming user device to connect to a home network of the inbound roaming user device. The method also includes identifying, by the network device, a PLMN selected by the inbound roaming user device, and accessing a listing of allowed PLMNs and disallowed PLMNs for roaming in the shared network. The method includes determining whether the selected PLMN is an allowed PLMN and blocking the connection to the home network in response to a determination that the selected PLMN is not an allowed PLMN.
