How reliable is DataESIM coverage on Cambodia's coastal islands like Koh Rong?

Connectivity on Cambodia's islands, including Koh Rong and Koh Rong Samloem, can exhibit variability. While DataESIM strives for maximum coverage, 4G LTE signal strength is generally strongest in developed areas such as main villages and resort zones. Remote beaches or less populated interior regions may experience degraded or intermittent service. For critical tasks, consider utilizing available Wi-Fi in established accommodations, though DataESIM often provides a more stable and private connection.
