Ubigi, a pioneer in eSIM solutions for connected travellers and professionals, ranks number one worldwide for connection quality in the Latency Report 2025. This independent study evaluates the real-world performance of eSIMs based on three key criteria: latency, Jitter and packet loss.
While Ubigi is ranked as the “undisputed champion” among 22 candidates for the Mbps speeds of its international eSIM, the Latency Report refocuses the debate on technical indicators that are fundamental for professionals: smooth video calls, stable VPN connections and reliable data transfers. To meet these quality requirements, Ubigi has deployed a state-of-the-art network infrastructure specifically designed to meet the needs of the professional world.
Ubigi, an innovative network infrastructure for performance
In this still young and uneven technological landscape, Ubigi has established itself as the benchmark for reliability and performance for connected workers. This performance is made possible by Ubigi’s global network architecture. To offer this quality of service, Ubigi relies on a high-level technical infrastructure, in particular traffic routing via seven Packet Gateways (P-GWs) strategically located in Europe, Asia, North America and South America. This international network allows data to travel through the Internet exit point closest to the user, limiting unnecessary traffic to the operator’s country of origin. The result: latency reduced by half to five times depending on the area, enhanced stability for real-time uses (video conferencing, cloud synchronisation, etc.), and network congestion avoided over long distances.
Four new P-GWs are being deployed over the next 12 months in North America, Europe and Africa, further strengthening Ubigi’s ability to deliver a seamless experience anywhere in the world.
Performance validated by the Latency Report 2025 for UBIGI
- Average latency: 35 ms in Europe, 92 ms in Asia, among the best responsiveness measured to date, essential for real-time exchanges such as video conferencing or VPN connections.
- Jitter: only 5 ms, placing Ubigi well above market standards and ensuring unparalleled fluidity during professional video calls.
- Packet loss: less than 0.2%, an exceptional result guaranteeing rock-solid stability even in extreme situations, such as a video conference combining screen sharing, simultaneous exchange of large files and cloud synchronisation.
This technical performance, which is well above the market average (and that of its competitors), has been rigorously validated by real-world testing in demanding international digital hubs such as Lisbon, Bangkok, Tbilisi, Mexico City and Cape Town.
Leading local partnerships for seamless connectivity
Ubigi’s quality also relies on its exclusive agreements with leading local operators, such as Orange in Europe and AIS in Thailand, enabling it to offer a connection that is superior to solutions based on secondary or shared networks.
“This ranking rewards our strategy of deploying a network infrastructure coupled with local agreements with leading operators to guarantee stable, smooth and uncompromising connectivity for all our users,” said Jacques Bonifay, President of Transatel.
A benchmark for mobile professionals
Speed isn’t everything. While high speeds are important, they often mask a more complex reality. A video call does not necessarily require 100 Mbps, but rather a stable connection without fluctuations or data loss. Latency, jitter and packet loss determine whether a remote meeting runs smoothly or becomes a nightmare. Ubigi is therefore the ideal solution for professionals who require a reliable and continuous connection, wherever they are in the world.
Ubigi is particularly suitable for:
- International teams working remotely,
- Consultants who are constantly on the move,
- Startups and SMEs operating internationally,
- And all professionals who need flawless connectivity.
“Our teams have been working since 2017 to establish this level of service quality. It is also this market-leading position that has enabled us to launch Ubigi for Business, our offering dedicated to companies that want to keep their employees connected anywhere in the world, with the best quality, a high level of security and optimal cost control,” adds Marie-Julie Le Guen, Director of the Ubigi Business Unit.
Where others sell “theoretical speed”, Ubigi delivers a simple promise: to stay connected seamlessly, reliably and without surprises — anywhere in the world.
