been expanded to a current 43 regions and with a customer base of over 44 million subscribers, Russia is Tele2's largest market by customer base. On 28 March 2013 Tele2 announced that they would sell their Russian operations to the bank VTB for US$2.4 billion plus $1.15 billion in net debt. Sweden Sweden is where Tele2 originated and it remains one of its strongest markets serving over 4 million customers. When the Swedish Post and Telecom Authority awarded four licenses for the 3G UMTS mobile networks in December 2001, Tele2 was among the winners. Notably Telia, the former telephony incumbent in Sweden, did not receive a license and so an agreement was established to build a 3G network shared by Tele2 and Telia using Tele2's license. SUNAB builds, owns and operates that 3G network. A similar company, Net4Mobility, was formed in 2009 between Tele2 and Telenor Sverige for the purpose of building a joint 4G LTE network. Unlike 3G, both said companies were awarded frequency licenses and so it is likely that this network will outperform other Swedish operators networks simply because there are more available frequencies for the customers. The 4G product was officially launched on 15 November 2010 and currently (as of May 2012) covers over 90 municipalities. "National" coverage, able to serve 99% of the population in Sweden, has an expected completion date at the end of 2012. As the equipment used by Net4Mobility can serve both LTE and 2G, the new network built primarily for LTE will also replace the aging 2G networks of Tele2 and Telenor, providing lower cost through shared infrastructure. In addition, it enables EDGE, a service previously not available via Tele2. On 24 May 2020, Tele2 became the first mobile network operator in Sweden to commercially launch a 5G NR network, initially in the Stockholm area and from 24 June 2020 was also extended to Gothenburg and Malmö.

The Post Office had grounds to terminate the contract at the start of 2004 because of the failure of the Tele2 companies to provide a parent company document due at the end of 2003.
