Today, it is possible to bring a phone up Mount Kilimanjaro and make calls. However, the networks are extremely limited in this area due to its remote location and high elevation. While some networks have towers at certain points along the route, they can be unreliable or non-existent as you move further away from those areas. In addition, phones may struggle to get reception due to the windy conditions around the mountain’s summit. As such, if you plan on bringing your phone along with you during your trek up Mount Kilimanjaro, it’s important that you prepare accordingly by researching what networks will be available beforehand and investing in an external battery pack for when signals become weak or nonexistent.
