4S eSIM eSIM Data Plans for Réunion

No, 4S eSIM does not provide a truly unlimited data eSIM for Réunion. All plans that use “Unlimited” in the name have a hard data cap; after that cap is reached the speed is reduced to 1000 kbps. Travelers can choose from fixed‑data plans that offer large allowances—for example a 50 GB bundle valid for 30 days or a 20 GB bundle valid for 15 days. These fixed plans give a substantial amount of high‑speed data before the reduced speed applies and can be more cost‑effective for most users.

4S eSIM does not provide a phone number or SMS service for Réunion. Only data‑only eSIM plans are available from this provider for that destination. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and text communication, but the availability of these apps is not guaranteed and some destinations may block or restrict certain services. It is advisable to confirm that the VoIP apps you rely on are accessible in Réunion before purchasing a 4S eSIM plan.
