Nomad does not provide eSIM plans for Réunion that include a phone number or SMS capability. Only data‑only eSIMs are available. Travelers can use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection to make calls and send messages, but these require internet access and cannot replace a traditional phone number or SMS service. Before purchasing, verify that the VoIP services needed are accessible in Réunion, as some destinations may restrict or block specific applications.
