What is the expected CoreESIM signal availability while climbing Mount Kilimanjaro?

Updated April 22, 2026

Climbers on Mount Kilimanjaro can expect intermittent but surprisingly good signal coverage with CoreESIM, primarily leveraging local networks like Vodacom. Strategic cellular towers have been installed on the mountain, providing 4G signal at most major camps along popular routes such as Marangu and Machame. While continuous connectivity to the summit is not guaranteed, vital communication points are generally covered. This allows for essential check-ins and updates from various altitudes on the ascent.
