That is a good question. https://starlink.com/map shows neither Myanmar, Thailand or Laos having coverage.

Perhaps they were using the "roam" version (https://starlink.com/roam), which seems to work pretty much anywhere.

I manage a maritime starlink installation. The geofence rules are very odd. Starlink is not licensed in either Cambodia or Thailand. When my ship was in Cambodia starlink automatically disconnected, but when we sailed into Thailand it came back online - despite both countries not having starlink available.
