Connectivity on Cambodian islands like Koh Rong and Koh Rong Samloem exhibits variability. CoreESIM's network partners generally provide 4G coverage in established village areas and around major accommodation hubs. However, signal strength and availability may diminish significantly in more remote beaches, secluded resorts, or during transit between islands. Users should anticipate potential signal fluctuations in these less densely populated coastal regions.
