The catch: plans are data only, so you get no local phone number for calls or texts.

In Bangkok you’ll lean on data for Grab rides, maps around Sukhumvit and the markets, hotel bookings and translation. A Thailand eSIM gets you online at the airport without queueing for a SIM card.

  • 3–4 days in Bangkok: 3 GB ($5.99) is plenty for maps, rides and messaging.
  • A week or more: 5 GB ($7.99) or 10 GB ($10.99) gives you room for photos and video calls.

Visiting more than one country?

How to set up Saily for Bangkok

  1. Choose your plan on saily.com or in the Saily app.
  2. Install the eSIM from the app before you travel, and turn on data roaming for the Saily line.
  3. Land in Bangkok: the plan activates automatically when you arrive.

You have 180 days to activate a plan after you buy it, so you can set everything up at home, days before your flight.

Travel tips for Bangkok

Thailand’s data prices on Saily are low, so the 10 GB plan is often better value than topping up a small plan later. Download offline maps of Bangkok before you fly in case you land with your phone in airplane mode.
