This particular CoreESIM plan is geo-restricted to Laos. Upon crossing a land border, such as the Thai-Lao Friendship Bridge from Nong Khai into Vientiane, or any entry point from Vietnam, your data service will cease. For travelers with multi-country itineraries, CoreESIM recommends a regional ASEAN plan or separate country-specific eSIMs to ensure continuous coverage across borders.
