Summa Networks provides cloud-native Subscriber Data Management for 4G and 5G networks, with the flexibility to integrate with 2G environments when required. This allows operators to manage subscriber profiles, authentication and service access while supporting a smooth evolution from legacy core architectures to modern, modular networks.
As mobile networks evolve towards more dynamic and distributed architectures, multi-IMSI SIM deployments are becoming increasingly common. These configurations enable greater flexibility for operators, but they also introduce new challenges at the signaling level—particularly when different IMSIs are associated with distinct core network identities.
In an increasingly complex and demanding telecommunications environment, operators need solutions that are not only robust and scalable but also flexible and adaptable to the constant evolution of technology. At Summa Networks, we understand this need and have developed our solutions around a "Multi Vendor Core Mobile" approach
Australia’s emergency call outage shows why telecom resilience and accountability are vital. Discover the key lessons for reliable critical infrastructure.
The telecom industry is on the verge of its next big leap. While 5G has already reshaped connectivity, the arrival of 5G Advanced, driven by 3GPP Release 18 and beyond, will accelerate this transformation even further. It is not just an incremental update — it is the bridge between today’s 5G deployments and the networks of the future, paving the way for a more intelligent, flexible, and sustainable telecom ecosystem.
In today’s rapidly evolving telecommunications landscape, adopting a multi-vendor strategy has become a foundational pillar for operators and service providers aiming to enhance network resilience, optimize costs, and accelerate innovation.
