Serbia’s mobile telecommunications market has evolved significantly over the past few years. While the country spent several years preparing for next-generation connectivity through trials and infrastructure upgrades, commercial 5G services only became a reality at the end of 2025.
Data from GSMA Intelligence indicates that Serbia had 8.45 million cellular mobile connections at the end of 2025.
To provide context, it is common for the number of mobile connections to exceed the total population because many individuals use more than one SIM or mobile subscription. For instance, a person may have one connection for personal use and another for work purposes. The growing availability of eSIM technology has made it even easier for users to maintain multiple mobile connections in recent years.
GSMA Intelligence data shows that the total number of mobile connections in Serbia was equivalent to 127 percent of the country’s population in October 2025. Looking at recent trends, the total number of mobile connections in Serbia declined by around 215 thousand, or 2.5 percent, between the end of 2024 and the end of 2025. The data also indicates that 95.4 percent of mobile connections in Serbia can now be classified as broadband connections, meaning that they operate on 3G, 4G, or 5G mobile networks.
However, it is important to note that devices capable of connecting to broadband mobile networks do not necessarily use cellular mobile data. Some subscriptions, for example, may only provide access to voice calls and SMS services. As a result, the share of broadband connections should not be interpreted as a direct measure of mobile internet usage.
Today, the Serbian mobile market is served by three nationwide operators: Telekom Srbija (mts), Yettel Serbia (formerly Telenor Serbia), and A1 Serbia (formerly Vip mobile). Together they cover the entire country and are now transitioning from mature LTE networks toward full 5G deployments.
Based on July 2025 data from Opensignal, Yettel leads the Serbian mobile network market with the best overall experience, securing multiple performance and coverage awards. A1 is a strong competitor, winning several categories, while all operators offer 2G, 3G, and 4G, with 5G deployment expanding in major cities like Belgrade, Niš, and Novi Sad.
Telekom Srbija, operating under the MTS brand, remains the largest telecom operator in the country. It is majority state-owned and offers mobile, fixed broadband, television, and enterprise services.
The operator holds the largest share of the Serbian mobile market, accounting for about 42.7% of the country’s 8.1 million mobile subscribers as of 2024.
Telekom Srbija also leads in network infrastructure. According to regulator reports, it had the highest number of base stations across 2G, 3G, and 4G networks by the end of 2024, reflecting its strong nationwide footprint.
The company had previously conducted 5G trials with vendors such as Ericsson, testing use cases and performance in urban areas. These trials laid the groundwork for commercial deployment once spectrum licences were issued.
The second largest operator is Yettel Serbia, which was previously known as Telenor Serbia before a rebranding in 2022. The company is now part of the e& PPF Telecom Group and provides mobile, broadband, and digital services nationwide.
Yettel holds roughly 33% of Serbia’s mobile market, making it the second-largest operator behind Telekom Srbija.
In preparation for 5G, the operator invested more than €100 million to secure spectrum across key bands such as 700 MHz, 2600 MHz and 3.6 GHz. These frequencies enable a mix of wide-area coverage and high-capacity services required for next-generation networks.
The company has been positioning itself as a strong competitor through network upgrades and digital services, including fixed wireless broadband solutions based on 5G technology.
The third operator is A1 Serbia, part of the A1 Telekom Austria Group. Although smaller than its rivals, it remains a significant player in the Serbian telecom market.
As of 2024, A1 Serbia accounted for around 24.3% of mobile subscribers.
A1 has focused heavily on network modernization and digital infrastructure investments. The company has also announced major investment programmes aimed at expanding fibre infrastructure and strengthening its mobile network in preparation for the 5G era.
Serbia’s long-awaited transition to 5G finally took place in late 2025. The national regulator, RATEL, conducted a multi-band spectrum auction in November 2025 covering frequencies including 700 MHz, 900 MHz, 1800 MHz, 2100 MHz, 2600 MHz and 3.6 GHz.
All three operators: Telekom Srbija, Yettel, and A1, secured licences in the auction, each paying just over €100 million, bringing the total value of the spectrum allocation to around €300 million.
Shortly afterwards, the operators simultaneously activated commercial 5G networks in December 2025, marking the country’s official entry into the 5G era.
Initial coverage focuses on major cities and key tourist areas, with broader nationwide rollout planned through 2026. Users with compatible devices can access the new network where coverage is available.
Serbia’s telecom sector is now entering a new phase of development as operators shift their focus from LTE expansion toward advanced 5G services.
In the short term, operators are expected to concentrate on expanding coverage in urban areas and introducing 5G-based fixed wireless broadband as an alternative to legacy fixed connections.
Over the longer term, the deployment of standalone 5G cores and the expansion of fibre infrastructure will likely play a key role in enabling new digital services, supporting industry modernization, and improving broadband connectivity across both urban and rural regions.
Serbia’s entry into the 5G era represents a significant milestone for the country’s digital economy. With spectrum secured, infrastructure investment under way and competitive pressure among operators increasing, the market is positioned for substantial progress in the years ahead.
