Yes, EastESIM generally provides good connectivity on popular remote islands such as Koh Rong in Cambodia, especially near main villages and developed beach areas. While signal might be weaker in very secluded parts of the island or during boat transfers, you'll typically have enough coverage to share stunning beach photos, communicate with tour operators, or check online maps. EastESIM partners with leading Cambodian networks like Cellcard and Smart Axiata to ensure you can stay connected even when enjoying the serene beauty of these island paradises, just a boat ride from Sihanoukville.
