Best Connect eSIM does not provide a Réunion eSIM that includes a phone number or SMS capability. The available plans from this provider are strictly data‑only, so travelers will not receive a local or international calling number with the device.
Because of this limitation, users who need voice or text communication can normally rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, the availability of these services can vary, and some destinations restrict certain apps or VoIP traffic, so travelers should confirm that the apps they plan to use are accessible in Réunion before purchasing a plan.
