This specific DataESIM plan is provisioned for exclusive use within Hungary and the broader EU zone. It is crucial to understand that if your travel itinerary includes non-EU countries, such as a train journey from Budapest to Belgrade (Serbia) or into Ukraine, your data connectivity will cease upon crossing the EU border. For travelers with multi-country European itineraries that span both EU and non-EU nations, we highly recommend our regional Europe eSIM plans, which provide seamless coverage across a wider array of destinations.
