Will my eSIMAdventures plan provide internet coverage during hikes in Réunion, such as at Piton de la Fournaise or within the 'Cirques'?

For the most part, yes! eSIMAdventures leverages Réunion's excellent French network infrastructure. You'll typically find a strong 4G/5G signal at popular viewpoints like Piton de la Fournaise and within the main villages nestled in the 'Cirques' (e.g., Cilaos, Salazie). However, as with any mountainous, remote terrain, deep valleys or very isolated trails might have intermittent service. We recommend downloading offline maps and guides beforehand as part of your expedition prep, ensuring you're always prepared, even in the most secluded corners.
