The company trades under the O2 brand.

Telefónica Germany was founded in 1995 as Viag Interkom, as a joint venture between British Telecommunications (45%), VIAG (45%) and Telenor (10%). Viag Interkom was awarded Germany's second GSM-1800 (also known as E-Netz (de; lit. E-Network in Germany) license in February 1997 and began operations on 1 February 1998 in eight cities.

In 2001, BT acquired VIAGs remaining shares for €11.4 billion, and the company was renamed BT Germany, it became a part of BT Wireless, a group of subsidiary companies owned by BT. BT Wireless demerged from BT in 2001 to form mmO2 plc and Viag Interkom was relaunched as O2 Germany.

Since 2004, the so called Uptown Munich is O2's German headquarters. The 38-story highrise is the tallest building in Munich, designed by architect Christoph Ingenhoven.[2]

In 2005, mmO2 plc. of which O2 Germany is a part, was acquired by Spanish telecoms giant, Telefónica. Telefónica additionally took over O2's subsidiaries in Great Britain and Ireland for a total of £17.7 billion as part of its expansion strategy into Europe.[3] As a new subsidiary of Telefónica, Telefónica O2 Germany rebranded as Telefónica O2 Germany GmbH in 2008.[4]

In 2010, Telefónica O2 Germany merged with HanseNet. The merged company was renamed to Telefónica Germany.[5]

In a bid to boost revenues of up to €1.68 billion earmarked to flow into debt reduction, Telefónica announced its subsidiary, Telefónica O2 Germany, would be making an IPO (initial public offering). The IPO would involve the sale of a minority stake (23%) of the subsidiary on the 30 October, 2012, prior to which point they had proceeded through a change in legal form.[6]

Post IPO

[edit]

Following the transition, in March 2013,[7] Telefónica Germany was incorporated into the TecDAX stock exchange index. In July of the same year, media reports stated that the company had proposed a merger with its rival, E-Plus, a German subsidiary of Royal KPN NV.[8] The merger created the largest mobile phone provider in Germany in terms of network connections.[9][10] The planned merger initially received resistance from a minority shareholder of E-Plus, America Movil SAB, but this was overcome in August 2013.[11]

In mid-2014, the European Commission approved the sale of Dutch telco provider KPN's German subsidiary, E-Plus, subject to certain requirements being met. These included the transfer of 30% of network capacity and certain assets among other assurances.[12][13] In exchange, KPN received €8.6 billion (€5 billion of which was cash).[14][15]

In September 2014, Telefónica Germany announced the sale of €3.62 billion in new stock to help finance the acquisition of its competitor E-Plus from KPN. As part of the purchase, Telefónica reduced its stake in its subsidiary to 62.1%.[16]

In 2019, the European Commission accused Telefónica Germany of breaching the commitments it made when acquiring E-Plus in 2013. The statement of objections sent to the German company included potential fines or a reversal of the merger. Investigations found that Telefónica Germany did not offer competitors the "best prices” for access to their 4G network. The European Commissioner for Competition, Margrethe Vestager, urged full compliance with commitments made in merger decisions. Telefónica Germany responded that they acted in full compliance with the remedy in response to the Commission's objections.[17]

In June 2020, Telefónica announced the sale of 10,100 mobile sites to Telxius for € 1.5 billion.[18]

Most of O2 plans are available both in a pre- and post-paid version, including the all-in-one-flatrates called o2 o and o2 on for enterprise customers. Beside the core business, Telefónica Germany is one of the largest retailers for mobile phones and tablets without a SIM lock. It was the first operator offering both Apple's iPhone 4 and the iPad 2.[19] Also, Telefónica Germany offers hosting services for large and midsized companies, serving some well-known portals including Spiegel Online and Sevenload. Together with Microsoft and Visionapp, Telefónica Germany provides a cloud service for Hosted Exchange.[20]

In December 2018, Telefónica Deutschland started to test the 5G on 5 sites in Berlin, in a partnership with Nokia.[citation needed] In December 2019 the company announced the rollout of the 5G Network, starting with Berlin, Hamburg, Munich, Cologne, and Frankfurt. Telefónica Deutschland is using Huawei and Nokia technology on the mobile radio sites.[citation needed]

Historical Development

Origins as O2 Germany


Viag Interkom was established on July 21, 1995, as Germany's fourth mobile network operator, entering the market dominated by D1 (Deutsche Telekom), D2 (Mannesmann, later Vodafone), and E-Plus (KPN). The company operated as a joint venture with initial ownership split between VIAG AG (45%), British Telecommunications (BT, 45%), and Telenor (10%), focusing on GSM 900/1800 MHz services and nationwide coverage through infrastructure investments. In August 2000, BT agreed to acquire control of Viag Interkom by purchasing VIAG's stake for approximately £4.3 billion, increasing its ownership to 90%. This transaction received European Commission approval in February 2001, after which BT bought out Telenor's remaining 10% stake, achieving full ownership of the operator, which had around 2 million subscribers by that time. BT demerged its global wireless operations, including Viag Interkom, in November 2001 to form mmO2 plc as a standalone entity listed on the London Stock Exchange. On May 1, 2002, Viag Interkom was relaunched under the unified O2 brand across mmO2's European markets, emphasizing innovative services and customer focus to differentiate from incumbents. This rebranding aligned with mmO2's strategy to consolidate branding post-demerger, positioning O2 Germany as a challenger operator with growing market share through competitive tariffs and network expansion.

Telefónica Acquisition and Rebranding

By the first half of 2024, the company deployed 1,200 additional transmitters in major cities including , , , and , alongside virtualized RAN (vRAN) and Open RAN trials with to reduce vendor dependency and costs. Core network partnerships were renewed with in 2024 for dual-mode support and cloud infrastructure. Despite these advances, a 2020 regulatory review found shortfalls in meeting 2015 spectrum license coverage obligations, prompting accelerated investments. For fixed-line and , Telefónica Deutschland pursued infrastructure sharing to address coverage gaps without massive greenfield builds, signing a 10-year agreement in October with for access to its fiber-to-the-home (FTTH) network, covering up to 5 million households initially. This was extended and intensified in July 2024 to align with Germany's gigabit strategy, targeting nationwide fiber availability by 2030 through shared deployment in underserved areas. Collaborations extended to cable-fiber hybrids with since late for gigabit-speed upgrades. Plans for proprietary fiber expansion, potentially valued at €5 billion, were explored in but prioritized wholesale access to optimize amid competitive dynamics. Market strategies post-2015 emphasized customer retention and acquisition through simplified branding and digital channels, including the phase-out of the Simyo discount brand and repositioning of Base as an online-only option to streamline operations and reduce multi-brand complexity inherited from E-Plus. A 2023 three-year plan focused on revenue growth via premium 5G tariffs, enterprise solutions, and digital transformation, culminating in mass-market 5G suitability by 2024 with expanded data usage over the network. Parent company Telefónica increased its stake to 97% by April 2024 through €2 billion in share purchases since late 2023, signaling commitment to long-term investments despite market challenges. Ten years post-merger in 2024, these efforts contributed to improved service quality and pricing competitiveness for mobile users.

The company's profitability benefited from its 'Accelerated Growth & Efficiency Plan,' initiated in 2024, which emphasized cost discipline in a competitive market while sustaining customer growth across segments. This approach improved EBITDA margins to around 31.8%, as cost reductions in operations and network maintenance counterbalanced lower service revenues. Investments exceeding €1 billion in network infrastructure continued, but were managed to align with efficiency goals, including better network utilization through wholesale adjustments. Cost management strategies focused on OPEX reductions via streamlined operations, such as legacy decommissioning and enhanced scale economics from higher network utilization. These measures sustained operating cash profitability, with Q1 2025 EBITDA increasing 2.2% year-over-year to €629 million despite ongoing market competition. Overall, the emphasis on has positioned Deutschland to maintain positive profitability trends amid revenue headwinds.

Market Position

Customer Base and Market Share

As of December 31, 2024, Telefónica Germany operated approximately 45 million mobile accesses, encompassing postpaid, prepaid, and machine-to-machine (M2M) connections, reflecting a stable base with a slight year-on-year decline of 0.2%. The company achieved net additions of 824,000 contract (postpaid) connections throughout , outperforming overall market growth in this segment and contributing to expanded coverage serving over 99% of the German population. These figures position Telefónica Germany as the third-largest mobile operator behind and , with gains in mobile service revenue (MSR) amid competitive pressures from emerging entrants like 1&1. In fixed-line services, Telefónica Germany maintained around 2.4 million customers as of mid-2024, primarily through DSL resold from Deutsche Telekom's supplemented by selective deployments and wholesale partnerships. This base experienced modest net growth, such as 3,000 additions in the first quarter of 2024, driven by bundled fixed-mobile convergence offerings, though overall fixed penetration lags mobile due to infrastructure dependencies. Fixed-line revenues rose 3.6% year-on-year to €857 million in 2024, indicating sustained demand despite a declining total customer count in the segment. Telefónica Germany's combined customer base underscores its focus on mobile dominance, with fixed services supporting hybrid bundles but holding a smaller market footprint estimated at under 10% in households, per industry analyses. Strategic expansions, including partnerships with entities like Lyca Mobile for additional distribution, bolstered postpaid growth and MSR share against , though total accesses remained flat amid economic headwinds and regulatory auctions.

Competitive Landscape

Telefónica Germany, operating under the O2 brand, competes primarily in Germany's oligopolistic telecommunications market, characterized by three dominant mobile network operators (MNOs)—, , and itself—alongside a growing number of mobile virtual network operators (MVNOs) and the emerging fourth MNO, 1&1. This structure has fostered intense rivalry in , network expansion, and service bundling, with mobile service revenues growing modestly amid adoption and data demand. maintains the largest market position, holding approximately 44% of mobile subscribers as of December 2024, leveraging its extensive and . follows as a key rival, emphasizing cable-fixed integration and international synergies, while 1&1's network rollout, initiated in 2023, introduces potential disruption through aggressive low-cost offerings, though it initially relies on wholesale access from incumbents like . In the mobile segment, commands about 32% of network service revenue as of September 2025, serving 34.7 million lines (excluding third-party operators) by June 2025, with strengths in urban coverage and prepaid segments but facing pressure from price wars and coverage gaps in rural areas compared to Deutsche Telekom's superior nationwide reach. Competition intensifies via MVNOs such as and Congstar, which leverage Telefónica's and rivals' networks for budget plans, eroding margins across operators. Telefónica differentiates through rapid deployment, achieving 98% population coverage by October 2025, outpacing some peers in speed metrics per independent tests, though overall experience awards like download speeds often tie or favor . The fixed broadband arena presents stiffer challenges for , where dominates with over 60% direct end-user share in 2024, bolstered by its DSL and assets, while excels in cable infrastructure for high-speed urban delivery. 's fixed-line revenues grew in 2024 through bundled mobile-fixed packages, but its remains modest, competing against regional providers and 1&1's expansions rather than leading in gigabit connectivity. Regulatory oversight from the Bundesnetzagentur enforces wholesale access to mitigate 's incumbency advantages, enabling competitors like to challenge via unbundled local loops, though persistent infrastructure asymmetries limit parity. Overall, the landscape drives convergence strategies, with operators like focusing on enterprise solutions and IoT to offset consumer segment saturation.

Merger Approvals and EU Scrutiny

In September 2013, Telefónica Deutschland announced its agreement to acquire , the German mobile subsidiary of , for €8.6 billion, a transaction that would consolidate the German mobile market from four to three nationwide network operators. The deal was notified to the under the Merger Regulation in April 2014, prompting initial concerns over potential reductions in competition for mobile services, including pricing and innovation. The Commission initiated a Phase II in-depth investigation on , 2014, extending the review timeline to assess impacts on retail and wholesale markets. Concurrently, the German Federal Cartel Office requested referral of the case to national authorities under Article 9 of the EU Merger Regulation to incorporate local spectrum and regulatory considerations, but the Commission rejected this on May 22, 2014, citing the cross-border nature of mobile competition effects. On July 2, 2014, the Commission approved the merger subject to structural and behavioral remedies designed to preserve competition. These included Telefónica's commitment to grant wholesale access to its LTE (4G) network for mobile virtual network operators (MVNOs) for at least five years, with capacity sufficient to support up to 12.5 million SIM cards and specific volume guarantees to enable MVNO expansion. Telefónica also pledged to transfer 25 MHz of spectrum in the 2600 MHz band to the German regulator for auction, facilitating potential entry or strengthening of a fourth competitor, and to honor pre-existing MVNO contracts without termination. Post-approval, the Commission scrutinized compliance, issuing a statement of objections on February 22, 2019, alleging had breached the wholesale access commitments by failing to provide adequate capacity and quality to MVNOs. After submitted evidence of remedial actions, including network upgrades and negotiations with affected parties, the Commission closed the infringement proceedings on March 12, 2021, without fines, determining the breaches were not intentional or systemic enough to warrant penalties. This episode highlighted ongoing EU monitoring of merger remedies in concentrated telecom markets.

Competition Remedies and Ongoing Compliance

The European Commission approved Telefónica Deutschland's acquisition of E-Plus on July 2, 2014, subject to a package of remedies designed to mitigate the reduction of mobile network operators from four to three in Germany, which could have led to higher prices and reduced competition for mobile virtual network operators (MVNOs). These included commitments to provide wholesale network access to a third-party mobile network operator (MNO) for up to 30% of post-merger subscriber capacity across 2G, 3G, and 4G services for 10 years, alongside an upfront Mobile Bitstream Access (MBA) remedy offering up to 20% of the merged entity's network capacity (with an optional additional 10%) to up to three MVNOs for data, voice, and SMS services. To address spectrum asymmetry, Telefónica was required to divest 2x10 MHz in the 1800 MHz band to an existing MNO for 15 years and lease additional spectrum in the 2.6 GHz and/or 2.1 GHz bands to a potential new MNO entrant at specified prices until 2025 or 2020, respectively. Further supporting MVNO viability, the remedies mandated hosting at least four additional MVNOs or service providers within three years, targeting a minimum of 2.5 million subscribers, with non-discriminatory access extended to all MVNOs six months after the upfront MBA launch and existing wholesale contracts prolonged until the end of 2025, including removal of restrictive clauses like customer transfer penalties. National roaming was offered to a new MNO entrant for up to 20% capacity in rural and urban areas until the end of or five years post-launch. These measures aimed to preserve MVNOs as competitive constraints, enabling them to capture up to 10.5% market share over five years and offsetting the loss of as a price challenger, where simulations indicated potential price rises of 4-6% in post-paid segments and 12-20% in prepaid. Implementation involved securing an upfront MBA agreement with Drillisch (now 1&1) in June 2014, granting access to 20% of the post-merger network capacity to facilitate MVNO entry. Oversight was enforced through a Monitoring Trustee, appointed by and approved by the Commission, responsible for quarterly capacity assessments, agreement reviews, and semi-annual reporting, with arbitration for disputes. The Bundesnetzagentur coordinated on aspects, authorizing combined use while planning auctions to reduce asymmetries by December 31, 2016. In February 2019, the Commission issued a statement of objections alleging breached behavioral commitments, particularly regarding wholesale access terms for MVNOs, marking the first such action under EU merger rules. An investigation followed, but by 2021, the Commission concluded without imposing a sanction, determining no fine was warranted despite the alleged non-compliance. Most commitments, with durations of 10-15 years from 2014, have since expired as of 2025, shifting focus to general regulatory obligations under the Bundesnetzagentur, including spectrum extensions granted in March 2025 for 800 MHz, 1800 MHz, and 2600 MHz bands under competitive conditions. No further merger-specific compliance actions have been reported post-resolution. In 2019, the European Commission issued a statement of objections to Telefónica Deutschland, alleging breaches of commitments made during the 2014 approval of its acquisition of E-Plus, specifically regarding insufficient provision of wholesale access to mobile virtual network operators (MVNOs) as required to maintain competition. The commitments had mandated Telefónica to divest spectrum and offer discounted access deals to at least four MVNOs for three years post-merger to offset reduced market players from four to three national operators. Telefónica contested the allegations, arguing compliance through offered contracts, though the probe risked fines up to 10% of global turnover or divestitures; the matter concluded without further publicized penalties after Telefónica's rebuttal. A high-profile consumer dispute arose in 2019 when the Oberlandesgericht München ruled that must pay €225,000 in prepaid mobile credit to a customer who exploited a promotional offer from 2007 promising two cents per call as "Guthaben" (credit), accumulating value across 508 SIM cards via automated calls. The customer, interpreting the terms literally to demand cash payout rather than usage-only credit, initially sought over €300,000 based on resale values, but the capped it at after discontinued the program to curb abuse; the ruling upheld a lower 's decision, highlighting ambiguities in promotional under German law. In data privacy litigation, the Landgericht München I held in May 2023 that violated the General Data Protection Regulation (GDPR) by sharing customers' positive payment data with credit agency without explicit consent, ordering cessation in a case brought by Verbraucherzentrale NRW. appealed, and in April 2025, the Oberlandesgericht München overturned the ruling, finding the data transfer lawful under GDPR's legitimate interest basis for creditworthiness assessments in telecom contracts. Telefónica Deutschland faced a regulatory dispute with MVNO provider Transatel in 2021 over access to its network for (IoT) services; the Bundesnetzagentur ruled in Transatel's favor, mandating negotiations for an MVNO contract after Telefónica refused terms beyond voice and data roaming. This stemmed from broader obligations under Germany's Telecommunications Act to enable wholesale access, underscoring tensions in niche service provisioning. Patent litigation peaked in 2024 when settled over 100 cases against /O2, alongside and , without securing injunctions or damages, marking the end of Germany's largest troll campaign targeting telecom standards. The suits alleged infringement on mobile and technologies, but courts repeatedly invalidated claims, reflecting scrutiny on non-practicing entity assertions in the Bundespatentgericht.

Controversies and Criticisms

Service Quality and Customer Complaints

Telefónica Germany's mobile network, operating under the O2 brand, has received mixed evaluations in independent tests, with recent assessments highlighting improvements in coverage and performance despite persistent criticisms of reliability. In the Connect Mobilfunk-Netztest 2025, O2's network earned a "sehr gut" (very good) rating with 909 out of 1,000 points, marking the fifth consecutive year of this distinction and a 14-point increase from the prior test, though it trailed Deutsche Telekom's leading score of 970 points. The test evaluated factors including voice quality, data throughput, and availability across urban and rural areas, attributing O2's gains to expanded deployment covering 98% of the population as of June 2025. Customer-reported service quality remains a point of contention, with frequent complaints centering on inconsistent coverage, frequent outages, and slow data speeds, particularly in rural or indoor settings. User reviews on platforms like aggregate to low satisfaction scores, averaging 1.2 to 1.3 out of 5 stars from thousands of submissions as of late 2024 and into 2025, often citing "spotty" signal and unreliable connectivity as reasons for dissatisfaction. Anecdotal reports on forums echo these issues, describing O2 as the "worst network" among major providers for everyday reliability, though such sources reflect self-selected negative experiences and may not represent the broader customer base. Efforts to address complaints include enhancements in , as evidenced by O2's second-place finish in the Connect Hotline Test 2025 with 459 out of 500 points—its highest score to date—indicating improved response times and resolution rates compared to prior years. Despite these strides, Telefónica Germany has faced no major regulatory penalties from the Bundesnetzagentur specifically tied to in recent reports, though ongoing monitoring via handset-based measurements introduced in 2025 aims to verify operator claims against real-world performance. Overall, while empirical tests show competitive network metrics, the divergence with feedback underscores challenges in translating investments into perceived reliability.

Pricing and Market Practices

Telefónica Deutschland, branded as O2, employs competitive pricing strategies in Germany's price-sensitive market, focusing on affordable tariffs to maintain its position as the second-largest mobile operator by . The company has emphasized value-for-money offerings, with (ARPU) reflecting a of volume-driven growth amid commoditized services. In response to consumer surveys indicating demand for transparency, O2 launched updated mobile tariffs in October 2024, featuring flat-rate data and calls without hidden price components to differentiate from rivals. Criticisms of O2's pricing practices center on unilateral contract adjustments and undisclosed fees, which customers have reported as eroding perceived affordability. Contract terms often include clauses permitting annual price increases tied to inflation or operational costs, such as a €2.46 monthly hike notified to fixed-line subscribers in May 2025, requiring opt-out within a short window to avoid acceptance. Activation and connection fees, ranging from €40 to €50 per SIM or service, have been cited in disputes for inadequate upfront disclosure during sales, leading to unexpected initial charges. Billing inaccuracies, including overcharges for international data despite add-on packages, have fueled complaints on review platforms, contributing to O2's low Trustpilot score of 1.2 out of 5 as of recent assessments. While O2 attributes such issues to individual errors and promotes self-service tools for dispute resolution, persistent reports suggest gaps in billing transparency and customer verification processes. In wholesale contexts, pricing disputes with mobile virtual network operators (MVNOs) have arisen, though a 2021 arbitration upheld O2's pricing review without mandating retroactive reductions. These practices occur against a backdrop of regulatory scrutiny on predatory pricing, but no major fines specific to retail pricing have been imposed on O2 in recent years.

Employment and Restructuring Debates

In 2016, Telefónica Deutschland initiated a program targeting a reduction of up to 1,600 positions from its then-9,100 by 2018, primarily through voluntary early retirements and severance agreements to minimize compulsory redundancies. The company secured up to 500 early terminations initially, focusing on larger sites while emphasizing social compatibility under German labor laws, which prioritize avoiding forced layoffs where feasible. More recently, amid parent company Telefónica's global efficiency drive, discussions emerged in 2025 regarding potential job impacts in Germany following the announced search for a successor to long-serving CEO Markus Haas. Telefónica planned to eliminate 6,000 to 7,000 positions worldwide by year-end 2025, favoring voluntary exits for older employees similar to a 2024 program, though specifics for the German unit with approximately 7,800 employees remained unclear. In September 2024, Haas had explicitly ruled out major "me-too" job cuts at O2 Germany, citing stable operations despite industry-wide pressures. The leadership transition, tied to a broader strategic review, fueled speculation about intensified cost measures to boost profitability in a saturated market, but no formal announcements or union negotiations specific to German layoffs were reported as of October 2025. These developments contrast with more contentious restructurings elsewhere in the group, such as in where union-backed voluntary schemes still drew criticism for scale. In , —the primary union representing telecom workers—has not publicly escalated disputes over O2-specific cuts, reflecting a pattern of negotiated voluntary adjustments over strikes, though broader industry wage and condition talks continue amid economic pressures. No large-scale employee protests or legal challenges tied to recent German restructuring proposals have materialized, underscoring the subsidiary's relative operational stability compared to global peers.

Recent Developments

Strategic Initiatives Post-2020

Following the launch of its 5G network on October 3, 2020, Telefónica Deutschland prioritized extensive 5G expansion, achieving coverage for over 98% of Germany's population by October 2025. The company invested heavily in infrastructure, including a €450 million loan from the European Investment Bank in February 2020 to support the rollout, and increased capital expenditure by 17% to €1.3 billion in the subsequent year. By June 2025, over 1,000 sites had been upgraded to 5G, with an additional 500 transmitters deployed in the first quarter alone, focusing on urban and rural areas to close coverage gaps. This initiative drove data traffic growth, surpassing 1 billion gigabytes (1 exabyte) over 12 months ending October 2025. In parallel, Deutschland expanded its fixed offerings through a wholesale agreement with , initiating deployment of its own products on Vodafone's cable fiber network by the end of 2020. This move aimed to bolster capabilities and compete in the growing fixed-line market. Complementing network investments, the company introduced the , titled “Digital.Sustainable.Connected.,” which integrates into operations, targeting reduced emissions and enhanced digital inclusion. To drive enterprise growth, Deutschland emphasized services, securing new business customers and partnerships in 2025 to accelerate secure digitalization across . In 2024, following the exit of competitor 1&1 from certain spectrum sharing arrangements, the company launched a three-year Accelerated Growth & Efficiency Plan, redeploying freed capacity for enhanced and cost optimization. These efforts contributed to revenue growth of 2.9% to €3.74 billion in the first half of the ending June 2025, alongside a 7.2% rise in OIBDA to €1.157 billion.

2025 Leadership Changes and Efficiency Measures

In October 2025, Deutschland announced the departure of long-serving CEO Markus Haas, who had led the company since 2017, amid a strategic review aimed at enhancing competitiveness in the German telecom market. The initiated a search for his successor on October 7, with Haas remaining in his role until a replacement is appointed, despite a February 2025 contract extension to 2028 that was subsequently overridden. This move followed underwhelming Q2 2025 financials, including a 2.4% decline to €2.18 billion and a 6% drop in EBITDA to €520 million, prompting parent company to push for bolder leadership to address stagnant growth and intensifying competition from rivals like and . Reports also indicated potential changes at other executive levels, such as the Managing Director for Third Party Business, signaling a broader management reshuffle. Concurrently, Deutschland pursued efficiency measures, including plans to cut thousands of jobs via voluntary redundancies or alternative programs, as part of a group-wide effort to streamline operations and reduce costs amid high and shifting demands for AI and expertise. These initiatives align with 's overall 2025 target of €285 million in annual savings from reductions, primarily targeting non-core roles to fund network investments and . The German unit's actions were framed as essential for achieving revenue growth and maintaining EBITDA stability, with emphasis on operational agility in a market where rollout and infrastructure sharing—such as potential renewed ties with 1&1—remain priorities. No specific numbers for were disclosed by late October 2025, but the measures were positioned as voluntary where possible to mitigate union resistance, reflecting broader telecom sector pressures from and consolidation.
