Coverage on Cambodia's picturesque islands, including Koh Rong and Koh Rong Samloem, has seen significant improvements, though it can still be variable in very remote pockets. WestESIM provides strong 4G signal in primary tourist hubs and resort areas. For crucial connectivity, such as video calls or large file uploads, we recommend utilizing the robust signal available in these established zones. While exploring secluded beaches, expect intermittent service, but core areas will keep you connected.
