Is roaming free in Liechtenstein with our European (EU) or Swiss SIM card?

It's a bit tricky when it comes to roaming in Liechtenstein. While it's part of the EEA, so EU 'Roam Like at Home' rules *can* apply, Liechtenstein also shares a customs and telecom union with Switzerland, which is NOT in the EU. This unique situation can lead to signal hopping between networks and unexpected roaming charges for your group, especially if your primary SIM is Swiss. For clear, predictable costs and reliable connectivity for your whole crew, a Triply eSIM for Liechtenstein is a much simpler and stress-free option.
