Syniverse and BICS Forge Alliance to Unlock Global 5G Roaming

TAMPA, Fla. – March 03, 2026

In a landmark move set to accelerate the global adoption of next-generation mobile services, connectivity giants Syniverse and BICS have announced a strategic partnership to expand the reach of 5G Standalone (SA) roaming. The collaboration will see the integration of their respective 5G Signaling Hub solutions, creating a simplified and more efficient path for mobile network operators (MNOs) to deliver true 5G experiences to subscribers across international borders.

This alliance directly addresses the complex hurdles that have so far tempered the rollout of 5G SA roaming, paving the way for a future of ultra-low latency applications like cross-border IoT, cloud gaming, and global private networks.

Breaking Down the 5G Standalone Barrier

The promise of 5G Standalone—a network operating on a pure 5G core, independent of previous 4G infrastructure—has long been a tantalizing prospect for the telecommunications industry. However, translating this promise into a seamless global roaming experience has proven to be a formidable challenge. While over 60 service providers have launched public 5G SA networks, the transition to widespread international roaming has been sluggish.

The obstacles are threefold: technical complexity, stringent security requirements, and cumbersome commercial negotiations. Unlike the architecture of previous generations, 5G SA roaming demands a completely new end-to-end service framework utilizing HTTP/2 signaling. This shift requires MNOs to implement new network functions and protocols, most notably the Security Edge Protection Proxy (SEPP), which is essential for securing traffic between different operator networks.

Furthermore, the need for enhanced security frameworks, updated bilateral commercial agreements, and rigorous technical testing for each new roaming relationship has created significant friction, slowing deployment. Many operators have cited these complexities, alongside financial constraints, as primary reasons for delaying their 5G SA roaming plans. The Syniverse-BICS partnership aims to dismantle these barriers by creating a more streamlined, scalable ecosystem.

A New Architecture for Global Connectivity

At the heart of the collaboration is the integration and peering of the Syniverse and BICS 5G Signaling Hubs. These hubs act as central clearinghouses for roaming traffic, allowing MNOs to establish connections without engaging in arduous one-off negotiations for every new partner network. By connecting their hubs, the two companies are effectively creating a super-network for 5G SA roaming. An operator connected to Syniverse's hub can now more easily establish a 5G SA roaming relationship with an operator on the BICS hub, and vice versa.

"5G standalone roaming only works when operators can trust what happens the moment their traffic crosses a network boundary," said John Wick, Chief Product Officer at Syniverse. "Our job is to remove friction at that handoff, so operators are not negotiating one-off connections every time they want to launch a new roaming relationship. By peering with BICS, we're making it easier for operators to focus on delivering reliable experiences to people who expect their devices to work wherever they travel."

This peering arrangement leverages the 3GPP-defined architecture for 5G interconnect, where SEPPs manage the secure exchange of signaling traffic over the N32 interface. This model provides robust end-to-end security, message filtering, and topology hiding—critical features that protect network integrity while ensuring interoperability.

"Establishing global 5G SA roaming is fundamental to unlocking the full potential of 5G SA,” stated Jorn Vercamert, Chief Product Officer at Proximus Global. "Through our partnership with Syniverse, we are expanding the reach of 5G SA roaming and fostering a shared ecosystem that enables operators to deliver next-generation services at scale.”

Impact on Operators and the Competitive Market

For MNOs, the strategic alliance offers a clear path to accelerate their 5G SA roaming capabilities. By simplifying the interconnection process, it lowers the barrier to entry, reduces time-to-market for new roaming services, and potentially lowers the capital expenditure required for building out a global roaming footprint. This move is particularly significant in a competitive landscape where other major players like Mobileum and Tata Communications are also vying to provide MNOs with the tools for 5G SA migration.

The partnership between Syniverse, with its top-rated IPX network reaching 97% of mobile devices, and BICS, whose network provides connectivity to over 5 billion subscribers, creates a formidable force in the market. Together, they already enable a majority of international roaming traffic, and this deeper integration for 5G SA is poised to solidify their central role in the next era of mobile connectivity. For operators, this means access to a vast, pre-integrated ecosystem, enabling them to focus on service innovation rather than complex interconnect engineering.

Unlocking the Future of Low-Latency Services

Ultimately, the true significance of this partnership will be measured by the new services it enables for consumers and enterprises. Widespread, reliable 5G SA roaming is the key to unlocking a host of applications that depend on the technology's signature ultra-low latency and high bandwidth.

Cross-border IoT stands to be a major beneficiary. Industries from logistics to manufacturing can deploy massive fleets of connected devices that communicate in real-time across international borders, enabling smarter supply chains and more efficient factory operations. With 5G IoT roaming traffic projected to increase by over 250% in the next two years, the demand is clearly established.

For consumers, the most immediate impact may be felt in cloud gaming. The ability to play high-end, graphics-intensive games streamed from the cloud while traveling abroad, without lag or performance degradation, moves from a niche concept to a viable reality. Similarly, immersive Augmented and Virtual Reality (AR/VR) experiences, which are highly sensitive to latency, become more practical on a global scale.

Furthermore, the partnership supports the expansion of enterprise private networks and network slicing, allowing multinational corporations to create dedicated, secure virtual networks with guaranteed performance characteristics for their global operations. As 5G SA adoption continues to grow, with connections projected to reach over 3.6 billion by 2030, the foundational work being done by Syniverse and BICS will prove essential in transforming these future-forward concepts into everyday tools for business and leisure.
