Koh Samui eSIM

Need a Koh Samui eSIM before your island trip? Buy an AloOui Thailand plan for airport or ferry transfers, lodging details and maps where service is available. Choose a data allowance that fits your full stay, and save boat information offline before leaving shore.

Pick the right plan before departure

Daily Unlimited variants are available up to 30 days; Premium is not selectable on this Thailand product. Check the exact selected terms and price before buying.

Plan your island arrival

If you fly into Samui or arrive by ferry, keep your hotel's location and pickup details ready on your phone. Confirm the correct pier if arriving by boat, since transfer arrangements can vary. Save the address and booking number offline so you are not dependent on signal during arrival.

Ferries and nearby islands

For crossings to Koh Phangan or Koh Tao, check your operator's schedule and keep tickets and return arrangements accessible offline. Thailand product information lists these destinations, but service on open water and smaller islands may be weak or absent. Do not rely on the eSIM alone for navigation or emergency communications at sea.

Install before you travel

1. Confirm your exact device is eSIM-compatible and carrier-unlocked.
2. Choose a Thailand plan with validity covering every island and mainland stop.
3. Install the email QR code using stable Wi-Fi and follow its activation instructions.
4. On arrival, set AloOui as the mobile data line and review home-SIM roaming to avoid unwanted charges.
