Sweden has three main mobile operators: Telia Sverige, Tele2, and Tre (Three). Telenor and others operate as virtual carriers. HelloRoam eSIMs connect via Telia or Tele2, the country's two largest networks.
Sweden has 5G live across Stockholm, Gothenburg, Malmö, Uppsala, and most major cities. Both Telia and Tele2 expanded 5G significantly in 2024 and 2025. Average 5G speeds in Stockholm reach 300 to 500 Mbps.
Rural Sweden is where coverage patterns become interesting. Southern Sweden, including Skåne province, has dense 4G coverage throughout. Central Sweden along the E4 motorway corridor has continuous 4G. Northern Sweden, including Lapland (Lappland), has 4G in towns like Kiruna, Gällivare, and Abisko but sparse coverage on wilderness hiking routes. The Kungsleden (King's Trail) has signal at hut stations but drops between them. The Swedish west coast and the High Coast (Höga Kusten) have solid 4G in towns.
Ice hotels, Northern Lights tours, and Arctic Circle activities are based out of Kiruna, which has good 4G. Download offline Kungsleden trail maps before any multi-day hiking.
