Our verdict
Tre Sweden suits travelers who want a Swedish carrier plan with worldwide roaming already inside the monthly fee, rather than a prepaid data-only eSIM. Plans start at SEK 229, coverage reaches from 100 countries, and unlimited data applies in Sweden while unlimited plans carry a monthly cap abroad.

Pros and cons
Pros
- Roaming in the included worldwide bundle, covering the UK, Japan, Thailand, Turkey, Mexico and the US, comes with all mobile plans at no extra cost
- Unlimited data in Sweden, with unlimited plans limited to a monthly allowance in EU/EES and covered countries abroad
- A carrier plan rather than a data-only eSIM, running on Tre 4G, Tre 5G and Tre 5G+ with instant activation
- Top-ups are available, and support runs on email, chat and phone
Cons
- Unlimited data (unlimited data, 5g and instant activation) is a Sweden allowance, with a monthly cap in EU/EES and covered countries for plans sold as unlimited
- Data received through Tre's shared data feature abroad counts against your own quota, so extra allowance cannot be passed around
- The entry price is SEK 229 and plans are Swedish carrier subscriptions, which suits subscribers rather than a one-off trip purchase
Ready to try Tre Sweden?
Scored 8.8 / 10 by NomadCue.
Who it suits
- People living in Sweden who want an ordinary mobile plan with roaming already included
- Travelers heading to the UK, Japan, Thailand, Turkey, Mexico or the US who prefer a single Swedish bill
- Trips where a monthly allowance per billing period is easier to follow than per-gigabyte roaming
Who should look elsewhere
- Anyone buying a single-trip data eSIM, since eSIMGo.is starts at $0.99 and SimToIsrael at $25
- Travelers who need a longer country list, since Zwitchy reaches 200 countries
- Heavy streaming and hotspot users abroad, who will meet the monthly cap that comes with unlimited plans

Frequently asked questions
How much do Tre Sweden plans cost?+
Plans start at SEK 229 and are sold directly by the operator. Roaming in the included worldwide bundle is part of all mobile plans at no extra cost, so the same monthly price covers Sweden plus destinations such as the UK, Japan, Thailand, Turkey, Mexico and the US. Top-ups are available when more data is needed.
Is data really unlimited when I travel?+
Unlimited data applies in Sweden. On unlimited plans the allowance abroad is capped each month in EU/EES and covered countries, and shared data received abroad counts against your own quota. Coverage spans from 100 countries, so that cap is the limit to weigh for a long, data-heavy trip.
Which networks and speeds does Tre Sweden use?+
Tre Sweden runs on Tre 4G, Tre 5G and Tre 5G+, and 5G is available. It is a carrier plan from a Swedish operator founded in 2003 and trading as Hi3G Access AB, so a Swedish number and account are part of the setup rather than a travel-only profile.
How do I reach Tre Sweden support?+
Support runs on email, chat and phone, so phone, chat and email are all available alongside a help centre and a community. The team sits in Sweden, and the legal entity behind the plans is listed as Hi3G Access AB.
Is Tre Sweden an eSIM or a regular mobile plan?+
It is a carrier plan with unlimited data, 5G, instant activation and a home network on Tre 4G, Tre 5G and Tre 5G+, not a data-only travel eSIM. Travelers who only need data for a single trip may find a dedicated eSIM such as eSIMGo.is or SimToIsrael a lighter purchase.
How many countries does coverage reach?+
Coverage reaches from 100 countries, and the roaming bundle is the practical part of that reach for trips to the UK, the US, Japan and beyond. It sits in every mobile plan at no extra cost, so a Swedish subscriber can travel widely without buying a separate roaming pack each time.
Can I add data while I am abroad?+
Top-ups are available through the operator's shop, alongside separate roaming packs for Europe, North America, Asia, South America, Africa and the UAE. Unlimited plans stay subject to the monthly cap in EU/EES and covered countries, so extra purchases do not remove that limit.
