Yes, in key areas. This is the most important question. You will have a strong 4G signal in the main town of Buhoma and at the park headquarters (like Bwindi) for the morning briefing. On the trek itself, you will have a signal for the first part of the hike, but as you go deep into the rainforest to find the gorillas, the signal will become intermittent or drop. It is perfect for uploading your photos the moment you are back at the base.
