Will my DataESIM maintain internet connectivity during a helicopter tour over Réunion?

DataESIM will provide robust cellular connectivity at the departure helipads, such as those near Saint-Gilles or Pierrefonds, allowing for pre-flight communications and boarding pass access. However, once airborne and ascending to higher altitudes over Réunion's remote cirques like Mafate or mountainous regions like the Piton de la Fournaise, signal strength will naturally diminish and eventually drop. This is a standard characteristic of cellular networks when operating at significant altitudes and distances from ground-based towers.
