What it does

What can you do with your Thailand eSIM?

A travel eSIM is built for mobile data. You browse and stream like at home, but regular calls and texts work differently than with a normal SIM card.

  • Use mobile data

    Yes

    Your Thailand eSIM handles all internet on your phone.

  • Use WhatsApp

    Yes

    Your existing WhatsApp account and number keep working.

  • Call via WhatsApp or FaceTime

    Yes

    These calls run over mobile data, so your Thailand eSIM is enough.

  • Keep your own phone number

    Yes

    Your regular SIM card stays active alongside the eSIM.

  • Standard calls and SMS

    Via your own SIM

    Most travel eSIMs are data-only. Regular calls and texts run on your normal SIM.

  • Use as personal hotspot

    Depends on bundle

    Hotspot support varies per bundle and provider. Check the details of the bundle you choose.

Want to stay reachable on your own number? Keep your regular SIM active and use the Thailand eSIM only for mobile data.

Why an eSIM is useful in Thailand

Thailand is perfect for eSIM travel: data powers Grab, Maps, hotel apps and sharing trip updates.

Install before departure and enable data on landing — ideal for multi-city trips or island hopping.

Coverage in Thailand

Coverage is typically excellent in cities, tourist areas and along transport corridors. Some remote islands or jungle spots may vary.

  • 4G/5G in major cities and popular islands.
  • Essential for Grab, LINE and travel apps.
