Most travellers to Thailand pick between three things: roaming on their home SIM, a tourist SIM from the airport, or an eSIM they install before they leave. Here is a short checklist to help you decide, plus what the eTravelSim Thailand eSIM includes.
1. Check that your phone supports eSIM
The phone must be unlocked and eSIM-enabled. If it is not, an airport SIM is the simpler choice. Check your model before you buy.
2. Look at the network and the data you need
The eTravelSim Thailand eSIM runs on the DTAC network with 5G and LTE data. Plans run from 5 GB for 7 days to 100 GB for 10 days, or Unlimited for 7 or 10 days.
3. Think about when you want to be connected
An eSIM is delivered by email, instantly after purchase, so you can install it before you fly and have data the moment you land. An airport SIM means queuing at the counter after a long flight.
4. Decide if you need hotspot
The Thailand eSIM allows hotspot and tethering, so you can share data with a travel companion or a laptop.
5. Check the paperwork
eTravelSim activates automatically once installed, with no documentation required.
6. Compare the price on the day
The Thailand eSIM costs $8.49 for 5 GB (7 days), $9.99 for 20 GB (7 days), $12.99 for 50 GB (10 days) and $15.99 for 100 GB (10 days). Unlimited is $14.99 for 7 days or $18.99 for 10 days. Ask what the airport counter quotes for the same days and data, and compare.
7. Remember it is data only
The eSIM has no Thai phone number. You keep your home number on your physical SIM for calls and texts, and use the eSIM for data.
