As a guest with a UK or US SIM, will I incur roaming charges when using my phone in Austria?

For our international guests, understanding roaming charges in Austria is key to avoiding unexpected fees. If you hold a UK SIM card, most major UK carriers (like O2, Vodafone, or Three) have reintroduced daily roaming charges since Brexit, as Austria is an EU country. For guests with US or other non-EU SIM cards, international roaming rates are typically quite high. To ensure a predictable and budget-friendly experience, we highly recommend activating a HotelESIM plan for Austria. It offers transparent pricing and reliable connectivity, complementing your hotel Wi-Fi beautifully without the worry of roaming surprises.
