Will my SouthESIM internet work during a helicopter tour over Réunion?

You'll definitely have signal at the helipads in areas like Saint-Pierre or Saint-Paul before and after your flight, perfect for checking in or sharing pre-flight excitement. However, once you're soaring high above Réunion's incredible cirques like Mafate or the dramatic volcanic landscapes, expect your connection to become intermittent or drop entirely. This is quite normal for any mobile service when you're high up and away from ground-based towers. Enjoy the views – they're worth disconnecting for!
