DNA is shutting down its 3G network by the end of 2023


DNA shuts down its 3G network by the end of 2023. With the shutdown, frequencies and resources will be freed up for 4G and 5G connections and other new technologies, and DNA will be allocating resources to developing these. By the end of 2020, the 3G network accounted for only a little over 2% of mobile data transfers by DNA’s customers.

“At the end of 2023, the 3G network will have been providing telecommunications for almost 20 years. More modern access solutions like 4G and 5G achieve significantly higher data transfer speeds and have higher network capacities. Data transfer quantities in the 3G network have fallen significantly over the years. Now is a good time to retire the long-serving 3G network,” says DNA’s VP of Radio Networks Jarkko Laari.

A particularly important factor contributing to DNA’s decision is the desire to enable a better customer experience by updating technology. 4G and 5G networks offer significantly more capacity, greater reliability and faster speeds for the ever-growing demand in mobile networks than the 3G network does. With the dismantling of the 3G network, several frequencies will also become available for newer technologies.

The shutdown of the 3G network will not generally require any action from the customers, such as buying a new phone, as almost all devices in DNA’s network already utilise 4G and 5G networks. Older devices that cannot utilise 4G and 5G networks will automatically switch over to the 2G network after 2023. DNA is also aware that some other devices, such as some trail cameras and the payment terminals used by some corporate customers, operate primarily in the 3G network. However, devices like these are, by this point, quite old, and replacing them will likely also become necessary for other reasons before the end of 2023. If any devices like these still remain in the network at the point of shutdown, they will switch to using 2G data. 

DNA will also be contacting those corporate and institutional customers who are still using 3G in order to help them find replacement solutions. The long transition period is meant to ensure that remaining 3G customers have plenty of time to replace their devices and services with newer technology.

“Of course, the new access solutions are superior to 3G in terms of performance, but they are also more energy-efficient and environmentally friendly. The emissions of DNA’s radio network in relation to the quantity of data transferred have already fallen to only a fourth of what they were in 2016,” Laari notes. 

DNA currently offers mobile services in four different generations of mobile networks. These are naturally 2G, 3G, 4G and 5G. After the shutdown of the 3G network, the 2G, or GSM, network will continue to offer customers basic data services and phone calls. The population coverage of DNA’s 4G network in Finland has been nearly 100% for a long time now, and the population coverage of the 5G network is already 43%, or approximately 2.4 million people across 108 different towns and cities.

When 4G was introduced people around the world laughed at Finns – DNA Vice President describes how the joking ultimately turned into wonder and why Finland became a 5G pioneer that is letting go of old technology15.9.2021 09:00:00 EEST | Press release

In August 2021, DNA announced that it is closing its 3G network in Finland, bringing an end to an era of one mobile technology. Few people know that the reason behind Finland being able to abandon old forms of technology and quickly adopt new ones is a special Finnish characteristic that was once made fun of abroad. The jokes have transformed into wonder: how is a small northern country able to do this? The answer can be found in Finland’s long history with mobile and network technology and an exceptional pricing model.

Kun 4G otettiin käyttöön, suomalaisille naureskeltiin maailmalla – DNA:n johtaja kertoo, kuinka nauru muuttui lopulta ihmettelyksi ja miksi Suomi on nyt 5G:n edelläkävijä – ja luopumassa vanhasta teknologiasta15.9.2021 09:00:00 EEST | Tiedote

DNA ilmoitti elokuussa 2021 ajavansa 3G-verkkonsa alas Suomessa ja samalla yksi mobiiliteknologian aikakausi tulee päätökseen. Harva kuitenkaan tietää, että syy siihen, miksi Suomessa voidaan luopua vanhasta teknologiasta ja ottaa nopeasti käyttöön uutta, johtuu suomalaisesta erityispiirteestä, jolle aikoinaan maailmalla jopa naureskeltiin. Nyt nauru on muuttunut ihmettelyn aiheeksi: kuinka yksi pieni pohjoinen maa oikein pystyy tuohon? Syyt löytyvät Suomen mobiili- ja verkkoteknologian pitkästä historiasta sekä poikkeuksellisesta hinnoittelumallista.

DNA tutki: tässä ovat suomalaisten suoratoistosuosikit – kaksi selkeästi ylitse muiden9.9.2021 09:00:00 EEST | Tiedote

Netflix on selkeästi suomalaisten eniten käyttämä maksullinen suoratoistopalvelu, kertoo DNA:n teettämä tutkimus. Maksuttomista palveluista Yle Areenalla on vankka asema, ja se peittoaa suosiossa jopa YouTuben. Suomalaiset ovat myös ahkeria suoratoistopalveluiden tilaajia, sillä viidesosalla on käytössään vähintään kolme maksullista palvelua ilmaisten lisäksi.

DNA's 5G coverage includes half of Finns and 114 towns – the new locations are Aura, Ikaalinen, Kirkkonummi, Pertunmaa, Vesilahti and Äänekoski8.9.2021 09:30:00 EEST | Press release

The coverage of DNA's 5G network already includes 50% of Finnish residences, i.e. almost 2.8 million people, in a total of 114 different towns. The most recent locations connected to the network are Aura, Ikaalinen, Kirkkonummi, Pertunmaa, Vesilahti and Äänekoski. With regional expansions and an improved range of 5G devices, the strong growth of the popularity of 5G services continues.

DNA:n 5G-peitto kattaa puolet suomalaisista – paikkakuntia jo 114, uusina Aura, Ikaalinen, Kirkkonummi, Pertunmaa, Vesilahti ja Äänekoski8.9.2021 09:30:00 EEST | Tiedote

DNA:n 5G-verkon peittoalue kattaa jo 50 % suomalaisten asuinpaikoista, eli lähes 2,8 miljoonaa ihmistä, yhteensä 114 eri paikkakunnalla. Tuoreimmat verkkoon liitetyt paikkakunnat ovat Aura, Ikaalinen, Kirkkonummi, Pertunmaa, Vesilahti ja Äänekoski. Aluelaajennusten ja parantuneen 5G-laitevalikoiman myötä 5G-palveluiden suosio on edelleen selvässä kasvussa.
