Tre (3) and travel eSIM in Sweden
Tre (3) is one of the networks your eSIM may use in Sweden. Here is who actually decides which network you get, and what to do with that.

Quick answer
- 90 of the 90 Sweden plans we sell name Tre (3) as a reachable network, at 3G and 4G and 5G.
- Tre (3) runs LTE on B7, B20, B38 and 5G on n1, n38, n78; your phone needs at least one of them.
- Travel plans connect by roaming, so no plan can promise one specific network.
Tre (3) in brief
Tre is run by Hi3G Access AB (brand 3) on its own network; its site says the voice network reaches 99.3 percent of Sweden's population, citing PTS annual surveys.
We are not a reseller for this operator and we have not run our own field speed tests. The band and network details below come from the sources listed at the end of the page.
Tre (3)'s bands and technology
| Item | Tre (3) |
|---|---|
| LTE (4G) | B7, B20, B38 |
| 5G NR | n1, n38, n78 |
| 5G launched | 2020 |
| 3G | Shut down (2025) |
| Network code (MCC-MNC) | 240-02 |
Checked against the sources on 2026-10-11. Only the bands a source confirmed are listed; the network may run others too.
An eSIM can only use Tre (3) if your phone supports at least one band in this table. Before you fly, open your model's spec page on the maker's site and compare its LTE and 5G band lists.
Tre (3)'s coverage map
Tre (3) publishes its own coverage map. Look up the street or district you will stay in rather than the country as a whole, because coverage in town and out of town differs a great deal. The map shows Tre (3)'s own network; a roaming plan may not get every technology it shows.
Who licenses Tre (3)
Mobile networks in Sweden are licensed, and their spectrum assigned, by the Swedish Post and Telecom Authority (PTS). The bands above are the ones it allocates. A problem with the local network's own service goes to the operator first; a problem with your eSIM plan comes to us.
The plans on our shelf that name Tre (3)
From the supplier record behind each package, 90 of the 90 plans we currently sell for Sweden declare Tre (3) as a network the profile can reach, at 3G and 4G and 5G. The figure comes from the same catalogue that prices the plan pages, and it moves when the supplier revises the record.
A plan naming Tre (3) means the network sits in the list the profile may choose from. It does not mean your handset will stay on it. The priority order is the supplier's, and the signal where you stand decides.
Tre (3) beside the other networks in Sweden
| Network | LTE bands | 5G bands |
|---|---|---|
| Tre (3) | B7, B20, B38 | n1, n38, n78 |
| Tele2 | B3, B7, B8, B20 | n28, n78 |
| Telenor Sweden | B3, B7, B8, B20 | n28, n78 |
| Telia | B3, B7, B20 | n28 |
A band shared across networks is one a single phone can use on all of them.
Why plans do not name a fixed network
Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If Tre (3) is weak where you are, try selecting Tele2 or Telenor Sweden or Telia manually in the network settings, and keep data roaming on for the eSIM profile.
FAQ
Will my eSIM definitely connect to Tre (3)?+
90 of our plans name Tre (3) as reachable, but that is not a guarantee. Travel plans run over roaming agreements, so the network depends on the supplier behind the plan, your device and where you are.
Which bands does my phone need for Tre (3)?+
At least one of these, LTE: B7, B20, B38; 5G: n1, n38, n78. Your phone's band list is on the maker's spec page for your model, under "Cellular" or "Network".
Does Tre (3) run 5G, and will my plan get it?+
Yes. Tre (3) has run commercial 5G since 2020, on n1, n38, n78. A travel plan only gets it when the plan permits 5G, your phone supports one of those bands, and you are inside 5G coverage. Miss any one and you fall back to 4G.
How do I see which network I am on?+
Check the carrier name at the top of the screen, or open the mobile-network settings and look at the operator list. If signal is poor, try selecting a network manually instead of automatic, but only one your plan actually supports.
