Deutsche Telekom intensified its network modernization throughout Q3 2025, accelerating 5G deployment, expanding FTTH coverage, and ramping mobile and fiber investments across its European footprint. In Germany, the operator reached 98.8% 5G population coverage and expanded its fiber network to 11.8 million households passed—both key foundations for future convergence, unlimited mobile plans, and gigabit broadband. Across Europe, Deutsche Telekom’s national companies now cover 89.3% of the population with 5G and reach 10.9 million homes with gigabit-capable fiber.
Network capital expenditure also reflected this shift. In Germany, cash capex (before spectrum) totaled €3.3 billion, down slightly due to intra-year fiber build allocation but still tied heavily to 5G and fiber build-out. In the U.S., T-Mobile increased network-related capex to €6.7 billion, supporting 5G densification and new fiber assets following the Metronet acquisition. European units invested €1.4 billion in network upgrades, including spectrum wins in Poland and Slovakia and continued fiber and 5G rollouts.
In the U.S., the infrastructure story broadened. T-Mobile absorbed 3.3 million postpaid phone, 390k other postpaid, and 349k prepaid customers through the UScellular acquisition, while expanding its fiber footprint by adding 755,000 customers from Metronet. The operator also launched T-Satellite, an automatic satellite-to-mobile service that extends coverage beyond terrestrial reach. In Europe, fixed-mobile convergence continued: the MagentaOne FMC base reached 8.6 million customers, up 5.5% year-on-year .
Key Network Infrastructure Metrics (Q3 2025)
• Germany 5G coverage: 98.8% population coverage
• Germany fiber footprint: 11.8M households passed
• Europe 5G coverage: 89.3% population
• Europe fiber footprint: 10.9M households gigabit-enabled
• Germany capex: €3.3B (fiber + 5G), slightly lower YoY due to timing
• U.S. capex: €6.7B, driven by mobile densification + fiber expansion
• Europe capex: €1.4B for fiber, broadband, 5G, and spectrum
• Fiber cooperations: New FTTH partnerships in Karlsruhe, Munich (M-net), and Hilden
• Regulatory drivers: Germany enshrined telecom infrastructure as “paramount public interest” to accelerate fiber deployment
“We reliably deliver strong figures in spite of all the challenges in our markets,” said CEO Tim Höttges. “And we want our shareholders to profit from this strength, too.”

🌐 Analysis
Deutsche Telekom’s 2025 network strategy is accelerating across three fronts: (1) closing Germany’s last mile to near-ubiquitous 5G and expanding FTTH coverage; (2) building a cross-European gigabit platform supported by spectrum renewals and regulatory fast-tracking of fiber; and (3) scaling T-Mobile US into a hybrid mobile–fiber operator through Metronet and Lumos customer acquisitions. Infrastructure investments—especially Germany’s fiber build, European 5G deployments, and U.S. densification—align with the company’s roadmap for converged services and low-latency applications like cloud gaming over 5G SA. This positions Deutsche Telekom competitively against Vodafone’s fiber JV strategy and Orange’s FTTH partnerships while reinforcing its multi-national 5G leadership.
