The modular core for mobile, IoT and private networks. Summa Networks consolidates every subscriber, policy, identity and connectivity function into a single Full Core software — helping carriers of all sizes move to 5G while they keep operating on 2G, 3G, 4G and 5G NSA. Modular by design Take the whole Full Core, or just the functions you need. Every element — HLR, HSS, SDM, UDM, UDR, PCRF, PCF — deploys standalone or fully converged, so you evolve at your own pace instead of ripping and replacing. No vendor lock-in. What we do One converged control plane, delivered as a single piece of software: HLR, HSS (LTE & IMS), SDM, UDM, UDR, AUSF, PCRF and PCF — plus AUC, EIR, DNS/ENUM, Multi-IMSI, SMSC, AAA, and Lawful Interception (HSM). Full support for voLTE, voWiFi, and Multi-IMSI. Who we serve MNOs, MVNOs, MVNE/As, Private LTE networks, IoT ecosystems, and secure communications. 40+ operators across 30+ countries. Why it matters Software that optimizes hardware means lower TCO and faster deployment. Modular architecture means no vendor lock-in and no forced migrations. You get the flexibility to grow — standalone or converged, 2G to 5G — on your terms. www.summanetworks.com
