What is DataESIM's signal availability during a hike through the Fish River Canyon?

DataESIM provides signal at the Hobas viewpoint and at established resorts situated on the rim of the Fish River Canyon. However, once users commence the multi-day descent into the canyon itself, particularly along the Fish River, cellular coverage becomes non-existent. This is a characteristic of such deep, geological formations. For safety and navigation, it is imperative to download all necessary maps and information offline prior to entering the canyon and consider satellite communication for emergency use.
