As of 2012, Globul's GSM network covers 99,98% of Bulgaria's population and 99,48% of the country's territory. The company has roaming agreements with over 400 operators in more than 170 countries and territories worldwide. In 2005, Globul received a license for developing and implementing 3G
UMTS mobile telecommunications network as well as a fixed telephony license. 3G services were launched in September 2006 and have since been upgraded to support
HSPA+ with speeds of up to 42 Mbit/s download and 5.76 Mbit/s upload. As of December 2012, Globul's UMTS network covers 94,81% of the country's population. Yettel uses the access code 089. Until 2003, it used the codes 099 and 098, the later having been added as the network had expanded. In mid-2003, however, mobile numbers in Bulgaria increased by one digit (by adding an initial
-8-) and the network code changed to 089 only. Alongside Globul, OTE had also owned one of the two
public telephone networks in the country –
BulFon, which it sold back to the
Bulgarian Telecommunications Company in 2005. After Telenor acquired Globul was made the intent that the whole existing network (both 2G and 3G) shall be rebuilt. Later in a press release it was revealed that
Huawei had been selected. In early 2013 the process has already begun. Telenor created a specific webpage that shows in which region and when the network would be rebuilt. The deadline is by mid 2015. Telenor also said that the network that they build would be easily made 4G LTE when the market indicates that it is ready for it.
LTE Yettel offers 4G services under the LTE standard in the 1,800 MHz band to all of its customers from 1 December 2015 in 53 cities and 2 resorts with coverage to 56.73% of the country's population. Further expansion is expected in 2016, including Bulgaria's popular seaside resorts. The maximum speed of the Telenor 4G network is 75 Мbps. The service is initially available in Sofia and most of southern Bulgaria. By mid-December, Telenor's LTE service will cover all Bulgarian cities with a population of more than 20,000, including all regional centres and the most popular winter resorts. Telenor said it will continue to expand the coverage and the capacity of its LTE network, depending on spectrum availability, further into 2016. Telenor 4G services are available at no additional cost until 31 January 2016 to all customers with 4G-enabled handsets and SIM cards, which are all Telenor SIM cards (including 3in1 SIMs) purchased or replaced in the last several years. Users with older SIM cards will be able to replace them free of charge at any Telenor or official partner shop where a wide variety of 4G-enabled devices is also available after 1 December. In May 2016, Telenor was awarded 2x5MHz additional spectrum in the 1800 MHz band from CRC.The additional frequencies will be used for further improving the quality of the company's 4G LTE services by allowing Telenor to increase the maximum theoretical data speed in its 4G network to 100 Mbit/s.
5G Telenor Bulgaria completed Bulgaria's first live 5G video call during a public test session on 19 August 2019. On 10 June 2021, Telenor Bulgaria officially launched 5G services nationwide during an event in Burgas attended by several customers, dignitaries and government officials. During its 20+ years of history on the Bulgarian market, the company built a strong track record as a pioneer in wireless and beyond, launching Bulgaria’s first commercial 4G network in 2015, the first VoLTE service in 2018 and paving the way for the development of 5G with the country’s first 5G network test. ==Other==
