Telia coverage and network reach

Whose network does Telia use?

Telia has its own network in southern and western Finland. In the north and east it uses a network shared with DNA.

In northern and eastern Finland DNA and Telia use a shared network built and run by Suomen Yhteisverkko. The area covers about 62.5% of Finland's land area and about 28.5% of the population, bounded roughly by a line from Raahe to Loviisa. The shared network's 5G upgrade was completed at the end of 2024.

Telia's last 3G base stations were switched off in Helsinki in October 2024.

5G coverage and frequency bands

Telia uses the 700 MHz and 3.5 GHz bands for 5G. The low 700 MHz band carries far and passes through walls, so it brings 5G to rural areas and indoors. The 3.5 GHz band gives the highest speeds in built-up areas. The 26 GHz bands have been auctioned but are not in consumer use.

Telia enabled standalone 5G (SA) across its whole 3.5 GHz network in June 2022, but it is not available on all consumer plans.

Recent network changes

• In April 2026 Telia added capacity at hundreds of sites and moved the old 3G frequencies to 4G and 5G use.
• In Traficom's October 2025 tests Telia calls succeeded in Porvoo, but in Posio some calls did not connect.

How to check coverage at your address

1. Open the Telia coverage map and search for your address or town.
2. Look at 4G and 5G separately. The map shows calculated outdoor coverage, so the connection indoors may be weaker.
3. If you live on the edge of the network, ask neighbours or try the plan: the 14-day distance-selling cancellation right applies to plans ordered online.
4. For a cottage or a car, also check the competitors' maps, since the networks differ most in sparsely populated areas.
