Skyalo does not provide eSIM plans that include a phone number or SMS service for Réunion. The provider offers only data‑only eSIMs, so travelers will need to rely on data‑based messaging and calling services such as WhatsApp, Telegram or iMessage to communicate. Those services can generally be used over the data connection, although some destinations may restrict or block certain apps or VoIP services, so it is advisable to confirm that the VoIP apps you depend on are accessible in Réunion before purchasing an eSIM.
