The EU's "Roam Like at Home" regulation (2017) requires carriers to allow EU residents to use their domestic plans in other EU member states at no extra charge, subject to fair use limits. This significantly reduces the need for separate travel SIMs for EU citizens traveling within the bloc.
Non-EU travelers โ from the US, UK, Australia, Canada, etc. โ do not benefit from this regulation and typically face high roaming charges from their home carriers. For these travelers, a regional eSIM plan is the most cost-effective solution.
5G roaming agreements between European operators are still being finalized as of 2025. Most eSIM travel plans provide 4G LTE as the primary data tier, with 5G available only where the eSIM provider has specific 5G roaming agreements in place.
For travelers requiring 5G speeds specifically, verify with your eSIM provider which countries and operators support 5G roaming before purchasing.
