Can I expect free roaming in Réunion with my UK, US, or non-French EU SIM card?

The situation for roaming in Réunion with non-French EU, UK, or US SIM cards can be quite nuanced. While EU 'Roam Like at Home' technically applies, many carriers, especially from countries like Germany or Spain, often impose 'Fair Use Policies' in remote territories, which can cap or throttle your data. US and UK carriers typically charge premium international roaming rates, which can quickly become expensive. HotelESIM offers a predictable, cost-effective solution, ensuring you stay connected without unexpected charges.
