This specific DataESIM plan is precisely engineered for exclusive operation within Singapore. Its network provisioning is geo-restricted to the Singaporean cellular infrastructure. Consequently, any attempt to connect from an adjacent territory, such as crossing into Johor Bahru, Malaysia, will result in an immediate loss of data service. For itineraries involving multiple countries like Thailand or Indonesia, we recommend our regional Asia-Pacific eSIMs, which are designed for seamless multi-country coverage without interruption.
