eSIM and SIM cards in Liechtenstein

Good news: you are covered

• Liechtenstein is an EEA state, and the European Commission names it alongside Iceland and Norway as a country where roam-like-at-home applies.
• An EU or EEA SIM therefore works here at your domestic rates, on your domestic allowance. Buying anything local is money wasted.
• UK plans are a separate question. Several UK networks reintroduced European roaming charges after Brexit, so check yours rather than assuming.

The Swiss trap

• Switzerland is not in the EEA and is not covered by the regime.
• Liechtenstein is 25 km long and the Swiss border is the Rhine, a few minutes' walk from much of the country. A phone left on automatic network selection can settle on a Swiss network without telling you.
• Being billed as Switzerland for a day in Vaduz is a real way to lose money here, and it does not require you to leave the country.
• If the bill matters, select the network manually or watch what the status bar says. The Austrian border to the east is the harmless one - Austria is in the EU.

What to actually do

• Most visitors need no local SIM at all, and there is little point buying one for a country this size.
• On a non-European plan, an eSIM before you land is simplest, and covers the Swiss and Austrian legs of the same trip if you pick a regional plan.

eSIM

• An eSIM is live before you land and skips the shop entirely, which on a short trip is the whole argument for it.
• Check your phone takes one. Most flagship phones since 2019 do; most budget models do not.

Practical points

• Keep your home number reachable for two-factor codes. If you swap in a local SIM as your only card, bank apps that text a code to your home number stop working at the worst possible moment. A dual-SIM phone, or an eSIM alongside your home SIM, solves it.
• Wi-fi is widespread in cafes, hotels and stations.
