Top 10 eSIM providers for Stockholm in 2026
Airalo tops the Stockholm eSIM ranking for 2026. It offers Telia-network coverage at roughly €1.50 per GB with instant QR activation. The tie-breaker over Holafly and Saily is consistent signal strength through the Tunnelbana metro tunnels and across the archipelago ferries, where cheaper providers on Tre's network tend to drop.
Stockholm sits on 3 mobile networks. Telia covers roughly 99.8% of the populated area, including the deep-rock Tunnelbana stations between T-Centralen and Kungsträdgården on the blue line. Tele2 and Tre follow close behind in the city center but can wobble in the archipelago and inside older buildings around Gamla Stan. The scoring here weights network coverage at 40%, per-GB pricing at 35%, and activation simplicity at 25%, with deductions for documented hidden fees or throttling complaints on Trustpilot. An eSIM that routes through Telia or Tele2 starts with a natural advantage over one locked to Tre, particularly if you plan to ride the green line out to Farsta or take the Waxholmsbolaget ferry to Vaxholm.
The most common mistake is buying too much data. Stockholm's free municipal Wi-Fi, Stockholms Stads WiFi, covers most of Norrmalm and Södermalm well enough that you burn through far less mobile data than expected. A 5 GB plan tends to last 10-14 days if you connect at Kulturhuset, in the Centralstationen waiting hall, and across the SL transit system. The second mistake is activating at Arlanda Airport (ARN) before clearing customs and hitting a QR scanning failure with no Wi-Fi fallback. Download your eSIM profile over Wi-Fi before you land at Arlanda. Providers like Holafly and Airalo let you install the profile days in advance and activate when you step off the Arlanda Express at Centralstationen.
Airalo is not the right pick for everyone. If you need unlimited data for video calls during a 2-week stay, Holafly's unlimited Nordic plan at around €47 for 15 days likely works out cheaper than topping up Airalo's per-GB packages. Heavy data users in Södermalm or Kungsholmen, where Wi-Fi in older apartment buildings can be patchy, will blow through a capped plan faster than expected. Travellers who want a local Swedish number for booking restaurants on Östermalm or receiving SMS confirmations from Systembolaget should skip eSIM providers altogether and pick up a Comviq or Hallon prepaid SIM at the Pressbyrån kiosk in T-Centralen. That runs about 99 SEK and gives you a real +46 number, which some Swedish services still require for verification.
The full list
-
Airalo
Routes through Telia's network in Stockholm, so you keep signal in the Tunnelbana tunnels between Slussen and Gamla Stan. Per-GB cost sits around €1.50 on the Nordics package, and the QR activation takes under 2 minutes with no app required.
-
Holafly
Unlimited data on Telia's backbone means you can stream and video-call from a café on Södermalm's Götgatan without watching your balance. The 15-day Nordic plan runs about €47, which pencils out if you use more than 8 GB during your Stockholm stay.
-
Saily
NordVPN's eSIM arm connects to Tele2 in Stockholm, which covers the Arlanda Express route and most of the inner city reliably. Pricing dropped to around €4 for 1 GB in early 2026, a solid option for light-data travellers exploring Djurgården on foot.
-
Nomad eSIM
Solid Telia coverage across Kungsholmen and the western suburbs. The app stores multiple eSIM profiles, handy if you're continuing to Copenhagen or Helsinki after Stockholm. Per-GB pricing sits around €2.10 on the Scandinavia bundle.
-
Ubigi
Pre-installed on some Samsung and Windows laptops, which saves setup time at Arlanda arrivals. Coverage runs on Tre's network in Stockholm, solid in Norrmalm and Östermalm but can thin out on the red line past Mörby centrum.
-
Maya Mobile
Among the cheapest per-GB options for Stockholm at roughly €1.20 on the 3 GB Europe plan. Connects via Tele2, which holds up well through Södermalm and across the Djurgården ferry crossing to Skeppsholmen.
-
Roamless
Pay-per-MB model suits visitors who rely on Stockholm's free municipal Wi-Fi across Norrmalm and only need mobile data for the Tunnelbana commute or walking between Djurgården's Vasamuseet and Skansen. No unused-data waste.
-
Alosim
Clean QR activation that works on the Arlanda Express Wi-Fi during the 20-minute ride to Centralstationen. Uses Telia's network. Pricing is mid-range at about €2.50 per GB, but the activation simplicity earns its spot for first-time eSIM users.
-
Yesim
Offers a dedicated Sweden plan on Tre's network. Coverage is fine around Stureplan and central Östermalm, but users on Trustpilot have reported throttling after 1 GB daily in peak hours. Worth noting for budget travellers who stay near the center.
-
GigSky
Established provider with reliable Telia coverage around Gamla Stan and the Stadshuset waterfront. The per-GB cost is steep at roughly €5, which pushes it down the ranking despite strong signal and smooth Apple Watch pairing for walks along Strandvägen.
