Bulgaria Enjoys a Fantastic 5G Experience

Bulgaria’s telecom market was for some years affected by the difficult macroeconomic climate, as well as by relatively high unemployment and a shrinking population. These factors continue to hobble investment in the sector, though revenue growth has returned since 2019. There still remains pressure on revenue growth, however, with consumers migrating from fixed-line voice telephony to mobile and VoIP alternatives, while the volume of SMS and MMS traffic has been affected by the growing use of alternative OTT messaging services.

The mature mobile market has effective competition between A1 Bulgaria, Yettel (branded as Telenor Bulgaria before March 2022, the Telenor Group’s local unit that had been sold to the PPF Group in August 2018), and the incumbent operator Vivacom. Competition intensified following the implementation of a streamlined mobile number portability process. In addition, customer preference for bundled services has put pressure on pricing and encouraged operators to offer generous voice and data packages. This in turn has impacted on operator revenue.

Vivacom was sold to United Group in April 2020, following European Commission approval. The company is investing in network upgrades and its development of services based on 5G have stimulated other market players to invest in their own service provision. A1 Bulgaria and Vivacom both launched commercial 5G services in 2020.

Most European nations have a median 5G download speed below 200 Mbps. Bulgaria, however, shines as a 5G leader, and Sweden, Cyprus, Finland, Denmark & Norway excel as high performers.

All three operators have a good 2G and 3G coverage over 95% of the country. 2G is on 900 and 1800 MHz, 3G on 2100 MHz like in most of Europe. 4G/LTE is supported by all operators on 1800 MHz (B3) only, added now by 2100 MHz (B1) and 900 MHz (B8).

According to the most recent Open Signal report  A1 wins 12 awards out of a possible 13 — nine shared victories and three outright wins. A1 notably comes at least joint first in every single award category for overall and 5G experience, winning three speed awards outright (Download Speed Experience, 5G Download Speed and 5G Upload Speed), and shares Consistent Quality with Yettel.

A1 reported on its website that it has completed the integration of a Standalone (SA) 5G network consisting of a Nokia-supplied Radio Access Network (RAN) and Ericsson’s dual-mode 5G Core backbone network, with the latter vendor taking a lead role in the integration project. Todor Tashev, Network & Services Senior Director at A1 Bulgaria, confirmed that 5G SA solutions are now available for B2B customers, who can ‘take advantage of the new technology to automate processes and solve complex problems’. The operator also highlighted the development of Private 5G SA network services as a key element of the Industry 4.0 concept, alongside massive machine-to-machine/IoT connectivity and ultra-reliable low-latency communication (URLLC) supported by 5G SA’s near-real-time transmission.

Vivacom  claim to own the best developed network in Bulgaria. They are the only telecom operator in the country that provides converged solutions through terrestrial, copper and satellite infrastructure, a mobile network and public Internet. They maintain the only networked international networking center in Bulgaria, the network management center and the largest real-time data storage and booking center. Vivacom owns its own infrastructure, which includes: a 5G network, they launched the first Bulgaria 5G network in all 27 district centers of the country in September, 2020. The fifth-generation network provides higher speed, lower latency, and more connected devices, which is an important condition for the development of areas such as telemedicine, digital education, gaming, automated production, and others.  According to the most recent Open Signal Report  Vivacom was the outright winner for 5G availability. 

Yettel  has over 3 million subscribers in Bulgaria, they believe in putting the customer first, Yettel's mission is clear: to help people achieve balance in life. During its 20-year history in the Bulgarian market, the company (operating until March 2022 under Telenor brand) has built a strong reputation as a pioneer in the field of wireless networks and beyond, launching the first commercial 4G network in Bulgaria in 2015, the first VoLTE service in 2018 and paving the way for the development of 5G with the first test of a 5G network in the country.

Bulgaria taking small steps towards 5G

Bulgaria has three major physical network providers in 2G, 3G and 4G/LTE:

A1 Bulgaria formerly known as Mtel (Мтел), owned by Telekom Austria
Telenor (Теленор): formerly known as Globul, owned by PPF Group
Vivacom (Виваком): taken over by Russian investors in 2015

The country has good 2G and 3G coverage over 95% of their area. 2G is on 900 and 1800 MHz, 3G on 2100 MHz like in most of Europe. 4G/LTE has been started by all operators on 1800 MHz (B3) only, added now by 2100 MHz (B1) and 900 MHz (B8).

All 3

A1 Bulgaria is owned by Telecom Austria and was rebranded in 2018 from Mtel (Мтел), and before that Mobitel (Мобилтел).

A1 Bulgaria  has commenced trials of 5G technology, following the activation of one base station at the National Palace of Culture in Sofia. The trial, utilising spectrum in the 3.6GHz band and equipment provided by Nokia, will run for six months. The operator is aiming to commence commercial operations over its 5G network in 2020.




In 2013 Telenor (part of PPF) from Norway acquired Globul from Cosmote in Greece. In 2014 they changed their logo and name from Globul to Telenor. In 2018 Telenor sold its Bulgarian network to the Czech PPF Group.They started 4G/LTE in 2015 on 1800 MHz (band 3) covering 75% of population in 2016.

Telenor commenced its series of practical 5G technology tests by introducing the first remote medical exam over 5G in Bulgaria. The examination of a patient was held by Prof. Asen Baltov, Executive Director of “N. I. Pirogov” Hospital, who was at the Telenor headquarters in Sofia,
During the event, Telenor also made its first 5G video call in Bulgaria. Telenor also intends to  perform demonstrations of 5G technology beyond Sofia covering numerous other geographic locations across Bulgaria. These tests will be related to virtual reality and the streaming of video content and gaming which will be made publicly available. To make this possible, Telenor will use Huawei equipment, which includes both fixed base stations, as well as a mobile base station that can be transported across the country.




Vivacom (vivatel or BTC, BTK) is the 3rd provider in the country, but still has a good coverage in 3G in Bulgaria. In 2015 they were sold to Russian-backed Spas Roussev.

4G/LTE started in 2016 on 1800 MHz (B3) in the towns of Sofia, Pernik and Vratsa. The 4G network was extended to Varna, Bourgas, Ruse and Plovdiv. The operator has the country’s largest towns within its LTE footprint and 2100 MHz band is added.

In other 5G developments the European Commission has stated that the Bulgarian and Greek transport ministers, Ivaylo Moskovski and Nikos Papas, and Tatjana Matić of the Ministry of Trade, Tourism and Telecommunications of Serbia, have signed an agreement at the Digital Assembly 2018 in Sofia to develop an experimental 5G cross-border corridor that will test driverless vehicles.

They agreed to work together on the Thessaloniki – Sofia – Belgrade corridor, which will provide a technologically neutral hub for industry, research centres, academia and any other stakeholders for testing and evaluating innovative mobility technologies.

Mr Moskovski stated that Bulgaria is now preparing its infrastructure to accommodate a 5G network for ‘connected driving’. European Commissioner for Digital Economy and Society Mariya Gabriel added that “we have agreed that the digital transformation has its challenges, such as cyber attacks and the online spread of misinformation” and that “people need to trust and be able to take advantage of this digitalisation.”
