Sonera, on the other hand, had a monopoly only on trunk network calls, while most (c. 75%) of local telecommunication was provided by telephone cooperatives.

Of the stock, 39.5% (31 March 2020) is owned by the Swedish government, and the rest by institutions, companies, and private investors worldwide.

The Finnish government (through Solidium) divested from Telia Company in February 2018, when it sold its remaining 3.2% stake.

On 1 July 1993, the remaining telephone and mobile network operator was transformed into a government-owned shareholding company, named Telia AB.

At the height of the dot-com bubble, on 13 June 2000, close to one-third of Telia's shares were introduced on the Stockholm Stock Exchange.

Private competition in analogue mobile phone systems had already broken the telephone monopoly, and the growing internet allowed more opportunities for competitors.

In December 2018, Telia in cooperation with Ericsson launched Sweden's first 5G network at KTH Royal Institute of Technology in Stockholm.

This agency governed all long distance and international calls until 1994, when competitors were allowed to enter the Finnish market.

During the run-up to the 2006 general election the Swedish liberal-conservative Alliance stated as one of its policy aims to reduce government ownership in commercial entities, and specifically to sell its stake in TeliaSonera.

Further divestment of TeliaSonera was however presented to the parliament only after the next election in 2010, when the Alliance lost its majority but stayed on as a minority administration.

[9] In the beginning of 2008, TeliaSonera announced measures to save nearly 500 million euros which would include 2,900 redundancies: 2,000 from Sweden and 900 from Finland.

[10] France Télécom (now Orange S.A.) proposed a 33 billion euro acquisition offer for TeliaSonera on 5 June 2008, which was promptly rejected by the company's board.

[26] Telia Company is the largest Nordic and Baltic fixed-voice, broadband, and mobile operator by revenue and customer base.

[28] Since 2014, Telia Finland and DNA Oyj have jointly deployed a shared 4G LTE network using the 800 MHz (LTE Band 20) "digital dividend" band in remote Northern and Eastern Finland under the Suomen Yhteisverkko Oy joint venture.

This was sold to Enitel during the merger attempt with Telenor, but Telia re-entered in 2000 with the purchase of one of the two mobile network operators, NetCom.

Telia Sverige is currently the largest mobile phone operator in Sweden, both in terms of revenue and customer base.

In July 2020, Telia Company announced it has divested its 12.25% share in the Afghan Roshan (telco) cellphone network.

In 2014, Telia and Telenor announced their plan to merge and create a 50/50 joint-venture, but this fell through in 2015 after failed negotiations with the EU regulators.

In February 2020, Telia Company agreed to sell its 100% holding in Moldcell to CG Cell Technologies DAC, for a transaction price of US$31.5 million.

On 21 December 2015, TeliaSonera announced its exit from Ncell, selling its 60.4 percent of the shares to Malaysian telecommunications group Axiata.

[39] TeliaSonera exited Nepal without settling billions of Capital Gains Tax owed to Nepalese government.

[41] Telia Company owned a 76.6% holding in the Spanish operator Yoigo until 21 June 2016 when it was sold to Masmovil.

Some former TeliaSonera executives were under preliminary investigation by Swedish prosecutors for allegations of bribery and money laundering associated with the acquisition of their 3G license in Uzbekistan from Takilant Limited, registered in Gibraltar.

In September 2017 Telia Company announced that a global settlement had been reached with the U.S. Department of Justice (DOJ), Securities and Exchange Commission (SEC) and the Dutch Public Prosecution Service (Openbaar Ministerie, OM) relating to previously disclosed investigations regarding historical transactions in Uzbekistan.

"[50] Further allegations have been presented in Swedish media and elsewhere that TeliaSonera may have illegally, through bribery, acquired licenses in Uzbekistan and Azerbaijan.

[5] When TeliaSonera exited Nepal there were voices raised in the public debate in Nepal that it had evaded an approximately 36 billion rupee capital gains tax owed to the Nepalese government, when it sold its stake to Axiata, a Malaysian Telecom Group, a claim which has been refuted by Telia Company on several occasions.
