How effective is CoreESIM's eSIM service within Sapo National Park?

CoreESIM generally provides signal in the towns surrounding Sapo National Park. However, once you enter the dense rainforest interior of the park, cellular coverage typically diminishes rapidly or becomes nonexistent due to the challenging terrain and thick canopy. It is imperative to download all necessary offline maps and information prior to commencing any treks within Sapo National Park for navigation and safety.
