As roaming evolves, so do the challenges
Inadequate security in legacy roaming protocols
Legacy protocols such as SS7 and Diameter were not designed for modern service-based architectures, increasing exposure to fraud, spoofing, signalling abuse, and network information leakage.
Secure by design mandates for 5G SA roaming
5G SA introduces 3GPP-mandated HTTP/2 over TLS and PRINS-based security requirements, making robust signalling security a foundational requirement for roaming interoperability.
Operational complexity at global scale
Roaming Scale Managing bilateral trust, certificates, policy alignment, and interoperability across multiple roaming partners increases operational complexity, slows onboarding, and impacts scalability.
