4S eSIM for Réunion FAQ
Does 4S eSIM offer unlimited data eSIM for Réunion?
No, 4S eSIM does not provide a truly unlimited data eSIM for Réunion. The plans that carry the “Unlimited” label are actually capped – each offers a set amount of high‑speed data and, once that limit is reached, the speed drops to 1000kbps. For example, the Reunion 50GB Unlimited – 15 Days plan supplies 50 GB of high‑speed data over 15 days, after which the connection slows to 1000kbps.
Travelers who need predictable data usage can choose from 4S eSIM’s fixed‑data plans that list the exact data allowance. A popular option is the 50GB plan valid for 15 days, which gives the full 50 GB at full speed without any throttling. Other high‑cap choices include the 20GB plans for 5 or 7 days. These fixed‑data plans are often more cost‑effective for heavy‑data users compared to the capped “Unlimited” packages.
Does 4S eSIM offer Réunion eSIM with phone number and SMS?
4S eSIM does not provide an eSIM for Réunion that includes a local phone number or SMS capability. Only data‑only plans are available for this destination. Travelers can still use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.
