Methodology
Our ranking methodology
We ranked each eSIM based on six criteria, weighted specifically for Thailand. Network reliability and price per GB carry the most weight: coverage is excellent in Bangkok and major cities, but gaps still exist on the islands and in the North. It's the choice of network and how the eSIM handles app filtering that makes the difference.
