DNA provides the City of Turku with communications services – better coverage for the city and more mobile tools for staff

Through the joint project, DNA has improved coverage and data transfer speeds throughout the city and neighbouring municipalities. DNA’s 4G and 5G networks have expanded with the establishment of dozens of new base stations, and the data transfer capacity has been increased in areas with high mobile data usage.
In addition, DNA has modernised the technical environment of the City’s communications services, giving City employees access to newer and more effective mobile applications.
“Switching the City’s telecommunications operator has been a big project, and having an excellent partner has been important to its success. The City’s goal during the project was to achieve cost benefits, improve reporting and minimise the outages caused by swapping thousands of plans. The most active phase of the project has come to an end, and going forward, we will be able to focus on realising the benefits of the swap,” explains the City of Turku’s IT Manager Joni Ilmanen.
“Good communications services help to boost the efficiency of work significantly. The City exchanges an enormous amount of important data on a daily basis, and DNA’s voice, mobile data and text message services, along with their associated applications, offer an excellent set of tools for reaching the right contacts and communicating effectively,” says DNA’s Sales Director Kenneth Grönroos.
“We are very pleased with our cooperation with the City of Turku and we want to be an active, easy-to-reach and constantly improving partner to them,” Grönroos continues.
The agreement between DNA and the City of Turku covers mobile communications in terms of both voice and mobile data for the thousands of City employees working in places ranging from schools to health centres, along with all the other functions of the City.
Both parties want to establish a long-term partnership.

Koulujen kännykkäkielto näkyy mobiiliverkossa: Datamäärät laskeneet paikoin merkittävästi, mutta koulukohtainen vaihtelu on suurta14.10.2025 08:30:00 EEST | Tiedote
Suomessa on elokuusta 2025 alkaen ollut voimassa lakiin perustuva kännykkäkielto peruskoulun oppitunneilla. Oppilaiden mobiililaitteiden käyttö on kielletty oppituntien aikana ilman opettajan lupaa, ja tällöinkin lähinnä opetukseen tai terveydenhoitoon liittyvissä asioissa. DNA:n tekemä vertailu kouluja palvelevien mobiilitukiasemien kautta kulkevan datan määrässä osoittaa, että kännykän käyttö kouluissa vaikuttaa pääosin vähentyneen –, joidenkin koulujen alueilla jopa merkittävästi.
The mobile phone ban in schools can be seen in the mobile network: Data usage has decreased significantly in some areas, but school-specific variation is huge14.10.2025 08:30:00 EEST | Press release
Since August 2025, a law-based mobile phone ban has been in effect during primary school lessons in Finland. Students are prohibited from using mobile devices during lessons without the teacher’s permission, and even then, only for educational or healthcare-related purposes. A comparison conducted by DNA on the amount of data passing through mobile base stations serving schools indicates that mobile phone use in schools has generally decreased – in some school areas even significantly.

Tutkimus: Valtiolliset toimijat vasta toiseksi suurin kyberturvallisuuden huolenaihe suomalaisyrityksille8.10.2025 10:00:00 EEST | Tiedote
DNA:n teettämän tuoreen tietoturvatutkimuksen* mukaan 70 prosenttia Suomessa toimivien yritysten ICT-päättäjistä on huolissaan kyberturvallisuudesta. Konkreettisessa varautumisessa on yrityksillä kuitenkin petrattavaa, sillä vain reilu neljännes harjoittelee kyberkriisitilanteita ja toiminnan palauttamista. Merkittävimpänä huolenaiheena pidetään yhä tietojen joutumista vääriin käsiin. Valtiollisiin toimijoihin kohdistuvan huolen osuus on laskenut hieman edellisvuodesta, mutta niihin liittyvä uhkakuva nähdään edelleen vasta toiseksi suurimpana. Tietoturvaan tehtävät investoinnit ovat puolestaan edelleen kasvussa.
