4S eSIM for Réunion FAQ
Does 4S eSIM offer unlimited data eSIM for Réunion?
4S eSIM does not currently provide a truly unlimited data eSIM for Réunion. All plans that carry the term “Unlimited” in their name actually have a fixed data cap; once that cap is reached, the speed drops to 1000kbps.
Travelers who need more data can opt for the provider’s fixed‑data plans. For example, a 50GB plan available for 5 days costs $26.90 USD, and a 10GB plan valid for 5 days costs $8.59 USD. These options give consistent high‑speed data for the specified period and may suit heavy‑usage travelers better than the restricted “Unlimited” plans.
Does 4S eSIM offer Réunion eSIM with phone number and SMS?
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.
