(PRESS RELEASE) STOCKHOLM, 7-Oct-2025 — /EuropaWire/ — Telia has entered into a long-term partnership with SJ, Sweden’s largest train operator, to provide advanced communications services across SJ’s operations and train fleet. The agreement spans mobile connectivity, Internet of Things (IoT) technologies, and crisis management solutions, forming a critical backbone for reliable, high-performance communications across Sweden’s transportation network.

As part of the agreement, Telia will supply comprehensive mobile connectivity and on-board Wi-Fi for SJ’s entire fleet of trains operating throughout the Nordic region and extending to Germany. In addition, Telia will equip SJ with mobile devices and support their digital ecosystem through high-speed and stable connections.

A key component of the collaboration involves the integration of Telia’s cutting-edge IoT solutions, enabling real-time data collection and monitoring of SJ’s systems. This will help enhance operational efficiency, optimize maintenance schedules, and contribute to more sustainable and data-driven train management.

In scenarios requiring emergency coordination, Telia’s independent crisis management platform will provide SJ with secure and rapid communication channels to maintain effective response capabilities during unforeseen events.

Fredrik Stenberg, Chief Commercial Officer & Head of B2B at Telia Sweden, emphasized the importance of the collaboration: “We’re proud that SJ has put their trust in Telia’s unique and robust infrastructure to strengthen their critical operations. This agreement is about reliability just as much as technology. Connectivity simply needs to work, and Telia will deliver on our responsibilities.”

SJ’s Chief Information Officer, Henri Caddeo, echoed this sentiment: “Our operations are defined by a high level of digitalization, so it’s crucial to have a partner that can offer stable connectivity and excellent coverage throughout the country. For this reason, we’re very pleased with this agreement with Telia. Our employees will be able to get the most from our digital systems and provide customers with the service they expect – on every SJ train in Sweden.”

Telia’s Swedish mobile network has consistently been recognized as the nation’s best for five consecutive years by the independent benchmarking organization umlaut, most recently in 2024. With its 5G coverage now reaching more than 99% of Sweden’s population, Telia continues to play a central role in supporting the country’s digital and transport infrastructure through innovative, reliable, and future-ready solutions.
