Telia Eesti, the Estonian subsidiary of Sweden’s Telia Company, says it plans to invest around EUR10 million (USD11.3 million) in the development of its mobile networks this year, a similar figure to its investment in 2019. The firm says that mobile voice and data usage increased significantly during the COVID-19 crisis and it has been continually upgrading and expanding its infrastructure, adding around 80 new 3G and 4G base stations between January and May this year. Telia is also working on adding a new frequency to its 3G service in and around the capital, Tallinn, to improve indoor coverage, while also upgrading its VoLTE service; VoLTE now accounts for 44% of calls on the Telia network.
