Mobile users generated around 71.8 billion minutes of voice traffic during the period, vastly exceeding the 1.3 billion minutes recorded on fixed-line networks.

Türkiye also maintained its position as the European country with the highest average monthly mobile call duration, with subscribers spending an average of 439 minutes per month on mobile calls.

Is competition in the telecom market increasing?

According to Uraloglu, competition among mobile operators remained strong, with approximately 3.5 million subscribers transferring their phone numbers between GSM providers during the reporting period.

The high level of number portability activity indicates continued competition among telecommunications operators as they seek to attract customers through expanded network coverage, faster data speeds and improved service offerings.

Explained: How 5G Drove Türkiye's Record Telecom Investment Boom in 2026

Türkiye's electronic communications sector recorded a historic surge in investment during the first quarter of 2026, with spending reaching 263 billion Turkish lira ($5.6 billion), a staggering increase of 1,300% compared with the same period last year. The sharp rise was fueled primarily by the country's long-awaited transition to fifth-generation mobile technology (5G), which officially entered commercial operation in April.

Transport and Infrastructure Minister Abdulkadir Uraloglu said the record investment levels reflected both the cost of acquiring 5G licenses and the substantial infrastructure spending required to support the next generation of digital connectivity.

Why did telecom investments increase so dramatically?

The main catalyst behind the investment surge was Türkiye's 5G spectrum auction, which took place in October 2025. Following the auction, telecommunications operators launched large-scale investments to deploy the infrastructure necessary for nationwide 5G services.

Unlike previous generations of mobile technology, 5G networks require significantly denser infrastructure, including upgraded mobile base stations, expanded fiber-optic networks and advanced data transmission systems capable of handling vast amounts of information with minimal delay.

As a result, telecommunications companies accelerated spending on both wireless and fixed-line infrastructure, leading to the highest level of investment ever recorded in Türkiye's communications sector.

How successful has the 5G rollout been?

According to Uraloglu, Türkiye's commercial 5G services officially launched on April 1, 2026, and adoption has been rapid. Within just a few months, the number of 5G subscriptions exceeded 43 million nationwide.

The rapid uptake reflects growing demand from consumers, businesses and industrial users for faster internet speeds, lower latency and improved network reliability. Fifth-generation networks enable applications that were previously difficult to support on older systems, including advanced industrial automation, artificial intelligence applications, autonomous systems and smart city technologies.

The government views the deployment of 5G as a strategic priority for supporting Türkiye's broader digital transformation agenda and improving the country's technological competitiveness.

Why has fiber infrastructure become increasingly important?

A major portion of the investment boom has been directed toward expanding Türkiye's fiber-optic infrastructure, which serves as the backbone of modern telecommunications networks.

Uraloglu said the country's total fiber-optic cable network expanded by 12.8% over the past year, increasing from 618,000 kilometers to 697,000 kilometers.

To illustrate the scale of the expansion, the minister noted that Türkiye's fiber network is now long enough to circle the Earth approximately 17 times.

Fiber-optic infrastructure is particularly important for 5G deployment because high-speed mobile networks rely heavily on fiber connections to transport large volumes of data between mobile towers, data centers and core network systems. Without extensive fiber coverage, many of the speed and capacity advantages promised by 5G cannot be fully realized.

Industry experts generally consider fiber deployment to be one of the most expensive but also one of the most critical components of next-generation telecommunications infrastructure.

How is Türkiye's internet market evolving?

The country's broadband market also continued to grow strongly during the first quarter of 2026.

According to government data, the total number of broadband internet subscribers reached 99.5 million, highlighting the increasing importance of digital connectivity for households, businesses and public services.

Among all broadband technologies, fiber internet recorded the fastest growth, with subscriptions increasing by 29.2% year-on-year. The rapid expansion of fiber services reflects growing consumer demand for higher internet speeds capable of supporting streaming services, cloud computing, remote work and online education.

The continued growth of broadband subscriptions also indicates that internet access is becoming an increasingly essential component of Türkiye's economic and social infrastructure.
