1. A method for identifying roaming messages at network functions in a home public land mobile network (PLMN), the method comprising:
receiving, at a home security edge protection proxy (SEPP) for the home PLMN, a request message from a consumer network function in a visitor PLMN;
adding, at the home SEPP, a header to the request message indicating that the request message originated in the visitor PLMN;
receiving, at a producer network function in the home PLMN, the request message;
determining, at the producer network function in the home PLMN, that the request message originated in the visitor PLMN by finding the header indicating that the request message originated in the visitor PLMN; and
applying, at the producer network function in the home PLMN, a roaming-specific policy while processing the request message in response to determining that the request message originated in the visitor PLMN.
