Connectivity on Cambodia's beautiful islands, such as Koh Rong and Koh Rong Samloem, is continually improving. With HotelESIM, you will generally find good 4G signal in the primary tourist areas, resort hubs, and around popular guesthouses. However, as you venture to more secluded beaches or remote parts of the islands, signal strength may become less consistent. It's an excellent backup for when you're away from your resort's Wi-Fi, but always good to download maps or information beforehand for deep island exploration.
