Can I expect free roaming in Réunion if I'm using a SIM card from the UK, US, or a non-French EU country?

Roaming in Réunion with a non-French EU, UK, or US SIM can be quite complex. While EU citizens theoretically benefit from "Roam Like at Home," many non-French carriers implement strict "Fair Use Policies" for overseas territories like Réunion, potentially capping or throttling data. For UK and US SIMs, Réunion is almost always considered outside standard roaming bundles, leading to very high pay-as-you-go rates. An EastESIM offers a predictable, cost-effective solution, ensuring you stay connected without unexpected charges while enjoying the island.
