It depends on the specific EastESIM plan you choose. If you've selected a single-country plan, for example, for Singapore, it will only function there, connecting to networks like Singtel. Once you cross into Malaysia, it will cease to work. For travelers exploring multiple destinations, EastESIM offers fantastic multi-country Asia Regional Plans that explicitly cover several nations, such as a plan for 'Southeast Asia' that includes both Singapore and Malaysia. Always verify the listed countries on your plan's description.
