Some eSIM providers partner with specific Thai networks (like AIS, DTAC, or TrueMove), which can affect your experience—check which network your plan uses if you’ll be off the beaten path. At major airports, you’ll often find free Wi-Fi and sometimes eSIM QR code kiosks for last-minute connectivity.
