This specific CoreESIM plan is geo-restricted to Mauritius only. Travelers planning multi-island itineraries, particularly those visiting Réunion Island, should note that Réunion is an overseas department of France and thus falls under EU roaming regulations. A Mauritian-specific eSIM will cease to provide connectivity upon entry into Réunion. For seamless connectivity across both territories, CoreESIM recommends selecting a regional plan that explicitly includes both Mauritius and Réunion, or acquiring separate, dedicated eSIMs for each location.
