Company Description
Turkcell Iletisim Hizmetleri A.S. (TKC) is a technology and telecommunications company headquartered in Türkiye. According to company disclosures and recent press releases, Turkcell offers a portfolio of voice, data, and IPTV services delivered over its mobile and fixed networks, and complements these with digital consumer, enterprise, and techfin services. The Turkcell Group reports operations in three countries: Türkiye, Belarus, and Northern Cyprus, and its shares are listed on both the New York Stock Exchange (NYSE: TKC) and the Borsa Istanbul (BIST: TCELL). Company materials state that Turkcell has been dual-listed on these exchanges since July 2000 and remains the only company with this dual listing.
Business model and operating segments
Turkcell presents itself as Türkiye’s leading telecommunications and technology company in multiple press releases. The Group organizes its activities into distinct reporting segments. As outlined in its 2025 quarterly results communications, Turkcell has three reporting segments:
- Turkcell Türkiye – This segment comprises telecom, digital services, and digital business services related businesses, retail channel operations, smart devices management, and consumer electronics sales through digital channels in Türkiye. It also includes mobile and fixed telecom operations and various group companies that provide digital, cloud, TV, call center, tower, and related technology services.
- Techfin – This segment includes all of Turkcell’s financial services businesses. Company disclosures describe this segment as covering brands and entities that provide digital payments, financing, insurance intermediation, and related financial technology services under the Turkcell umbrella.
- Other – This segment primarily comprises international operations, energy businesses, non-group call center activities, and intersegment eliminations. Entities in Belarus and Northern Cyprus, as well as energy-focused subsidiaries, are included here.
Earlier disclosures referenced three main reportable segments as Turkcell Türkiye, Turkcell International, and Techfin; more recent materials explain that, following the sale of operations in Ukraine, companies previously grouped under Turkcell International have been reclassified under the Other segment. The company notes that the change in segment structure does not affect operating profit, net profit, or cash flow figures.
Core services and technology focus
Across its communications, Turkcell describes a focus on mobile and fixed connectivity, digital services, and techfin. Its offerings include mobile and fixed voice and data services, IPTV, and a range of digital services for consumers and enterprises. Within Turkcell Türkiye, the company highlights activities such as digital business services, city hospital and hardware solutions, corporate terminal operations, and integrated channel management. Subsidiaries in this segment cover areas such as cloud solutions, TV and music services, digital communication platforms, call center operations, technology R&D, and data center services.
Turkcell’s public statements emphasize investments in fiber infrastructure, data centers, and cloud technologies. In multiple quarterly results releases, the company identifies its Data Center & Cloud business as a key strategic pillar, reporting strong year-on-year revenue growth in this area. The company also notes continued expansion of fiber homepasses and fiber subscriber additions, and describes fiber as a core strategic priority in its fixed broadband business.
Data center, cloud, and strategic partnerships
Recent announcements show Turkcell deepening its position in data centers and cloud services. In its 2025 quarterly communications, the company reports that data center and cloud revenues are growing faster than overall Group revenues and that active capacity at next-generation data centers has increased. Turkcell states that it aims to position Türkiye as a regional data hub and that it holds a leading role in the domestic data center market according to its own descriptions.
In a press release dated November 12, 2025, Turkcell announced a strategic partnership with Google Cloud. Under this partnership, Turkcell and Google Cloud plan to collaborate on delivering the infrastructure for a new Google Cloud region in Türkiye, consisting of three or more zones. Turkcell will act as a trusted partner and reseller of Google Cloud services in the Turkish market, with the goal of supporting organizations across industries in their transition to the cloud. The company states that this new region is intended to provide high-performance, low-latency cloud services, advanced capabilities in data analytics, application modernization, cybersecurity, and digital business solutions, and to support growing demand for cloud and artificial intelligence services.
Turkcell’s communications also describe murabaha-based financing agreements with financial institutions in the Gulf region to support data center expansion and broader infrastructure investments. A May 2025 release details a EUR 100 million murabaha financing agreement for its data center subsidiary TDC Veri Hizmetleri, intended to support high-capacity, eco-friendly data centers and digital infrastructure initiatives. Another May 2025 release notes a USD 150 million Murabaha financing from Dubai Islamic Bank PJSC, which the company links to strategic investments in data centers, cloud technologies, renewable energy, and core telecommunications services.
Mobile network, 5G spectrum, and network evolution
Turkcell’s quarterly reports describe it as Türkiye’s leading mobile operator, with more than 40 million subscribers cited in a March 2025 announcement regarding satellite direct-to-device (D2D) testing. In its third quarter 2025 results, the company reports securing 160 MHz of spectrum in a national 5G tender, which it states is the maximum capacity allowed for a single operator in that process. According to the same release, Turkcell now holds 394.4 MHz out of Türkiye’s total 949.2 MHz frequency resources, which the company calculates as approximately 42% of available spectrum. Turkcell characterizes this spectrum position as enabling it to deliver high 5G speeds and capacity and notes that its 2G, 3G, and 4.5G authorizations were extended through the tender.
In collaboration with technology partners, Turkcell is also evolving its network architecture. A June 2025 announcement with A10 Networks describes Turkcell’s use of carrier-grade NAT (CGNAT) infrastructure, integrated security solutions, and advanced telemetry to support scalability, reliability, and protection against cyber threats. The company is described as accelerating virtualization of its network infrastructure, including carrier-grade networking, Gi-firewall capabilities, and DDoS protection, and as achieving high virtualization rates in its network. Another March 2025 announcement with Odine and Mavenir highlights the use of a cloud-based wholesale voice management platform to automate provisioning and call routing, virtualize legacy interconnect systems, and introduce functions such as routing, billing, route optimization, fraud detection, and number portability within a software-defined environment.
Turkcell has also tested direct-to-device satellite connectivity in cooperation with Lynk Global. A March 2025 release states that the companies conducted field tests in a rural area of Türkiye with limited cellular coverage, using Turkcell’s mobile frequencies and Lynk’s low Earth orbit satellites to deliver SMS and voice services directly to standard mobile phones without specialized devices. Turkcell presents this as part of its efforts to enhance coverage and network resilience, particularly in rural and emergency scenarios.
Techfin and digital financial services
Within the Techfin segment, Turkcell’s disclosures describe a range of financial services businesses. The segment includes entities focused on digital payments, electronic money, consumer finance, insurance intermediation, and corporate rewards services. In its 2025 quarterly results, Turkcell notes that the Techfin segment accounts for a defined share of consolidated revenues and has delivered double-digit year-on-year growth, outpacing the Group overall in several periods.
Company communications highlight Paycell as a digital payment brand that enables customers to manage daily financial needs such as mobile payments, investments, bill payments, and money transfers within a single application. Turkcell reports strong revenue growth at Paycell, driven by increased transaction volumes in point-of-sale and mobile payment services, as well as enhancements like support for payments via multiple bank cards through a national QR payment system and two-way international money transfers. The company also references Financell as a provider of financing solutions for technological devices and vehicle loans, and notes the introduction of products such as small business device loans and foreign currency loan modules. These descriptions indicate that Techfin is intended to complement Turkcell’s core connectivity services with financial products delivered through digital channels.
