Vodafone Group and A1 Group have achieved a significant milestone by successfully enabling 5G Standalone (SA) roaming between their networks. This marks a successful connection of A1 Bulgaria’s subscriber to Vodafone Germany’s 5G SA infrastructure. The accomplishment was made possible by using commercially available 5G core network software compliant with the latest 3GPP standards, offering advanced voice capabilities such as immersive surround sound. Unlike Non-Standalone (NSA) 5G, which relies on LTE infrastructure, 5G SA operates using a cloud-native 5G core with Service-Based Architecture, unlocking the full potential of 5G features.
Alberto Ripepi, chief network officer at Vodafone Group, emphasized the enhancement of user experiences at international events and consistent connectivity across diverse business locations. The success of this trial was supported by Ericsson’s dual-mode 5G Core and Security Edge Protection Proxy (SEPP) platforms used by both Vodafone and A1, which ensure subscriber and network data protection during international usage in line with GSMA guidelines.
The trial’s adherence to 3GPP and GSMA standards simplifies the automatic setup and centralized management of inter-operator connections, streamlining roaming agreements and accelerating market entry. Todor Tashev of A1 Group highlighted the importance of this achievement in delivering high-quality mobile connectivity to European citizens and tourists alike. Monica Zethzon from Ericsson noted that out of over 60 live or deployed 5G SA networks worldwide, more than 40 utilize Ericsson’s core and radio solutions, ensuring consistent service quality and security. Roaming capabilities are crucial to meeting user expectations, especially during major events. Looking ahead, Ericsson’s Mobility Report projects that by 2030, 60% of global 5G subscriptions—approximately 3.6 billion—will be 5G SA-enabled. European consumers are also reportedly willing to pay up to 15% more for better application performance and connectivity, indicating a bright future for 5G SA with enhanced connectivity and user experiences globally.
