Connectivity on Cambodian islands such as Koh Rong and Koh Rong Samloem can be a mixed bag, much like the island's charmingly unpredictable weather. You'll generally find decent 4G signal in the main tourist hubs and guesthouse areas. However, as you venture to more secluded beaches or remote corners, the signal may become weaker or even non-existent. It's an excellent opportunity to truly disconnect, but don't count on streaming movies from every hammock.
