Liechtenstein is one of the smallest countries in Europe, and most visitors see it as a day trip from Zurich, St. Gallen or the Austrian Vorarlberg. The connectivity question is less about the country itself and more about its neighbour. Liechtenstein is a member of the European Economic Area, so EU roaming rules apply there. Switzerland, which surrounds it on the west and south and shares a customs union and currency with it, is not. Along the Rhine, a phone can hop between Liechtenstein and Swiss towers without you noticing. co:sim's Liechtenstein eSIM connects to FL1 (Telecom Liechtenstein, 5G) and 7acht (4G), and this guide explains when it is worth buying, how the plans compare, and why a regional plan is often the better choice.
EU or EEA phone plan: you roam at domestic rates while your phone is on a Liechtenstein network. The risk is being picked up by a Swiss network near the Rhine or in the south of the country, which is billed as non-EU roaming by many carriers.
Swiss phone plan: check your tariff. Many Swiss plans treat Liechtenstein as roaming.
UK, US, Asian or other plan: you pay your carrier's international roaming rate, so a prepaid eSIM is usually much cheaper.
The Liechtenstein eSIM lists FL1 (5G) and 7acht (4G). At the time of writing (October 2026) the options are:

#The better option for most trips: a regional plan
Very few people visit only Liechtenstein. Because the same trip almost always includes Switzerland, Austria or Germany, a regional plan usually makes more sense than a single-country one:
Europe (33 areas) covers Liechtenstein and Switzerland, Austria, Germany and most of the EU.
With a regional plan, it no longer matters whether your phone connects to a Liechtenstein or a Swiss tower: both are inside the plan. That removes the main connectivity risk of the trip.
Houses below the mountains in Liechtenstein's Rhine valley
The country is only about 25km long, and the Rhine valley towns of Vaduz, Schaan, Triesen and Balzers are densely covered. The alpine area around Malbun and the Steg valley is also served, although hiking routes on the higher ridges can have patchy signal. If you are hiking the Fürstensteig or crossing into Austria on foot, download the route and offline maps first.
Yes. Liechtenstein is in the EEA, so EU and EEA plans roam at home rates on Liechtenstein networks. Swiss networks, which you may pick up near the border, are not covered.
A co:sim Switzerland-only plan covers Switzerland only. For both countries, use the Europe (33 areas) plan, which includes Switzerland and Liechtenstein.
A day of maps, messaging and photos rarely uses more than 1GB. A daily plan or the smallest fixed plan is enough.
For most travellers the simplest answer is a regional plan that includes both Liechtenstein and Switzerland, so the border stops being a billing question.
