Thailand is built for travellers with a phone: ride apps, ferry bookings, island maps, street-food reviews. A travel eSIM means you skip the SIM counters at the airport and step into the humidity already online.
Networks and coverage
Our Thailand plans run on TrueMove H and DTAC, with good 4G/5G coverage in Bangkok, Chiang Mai, Phuket, Krabi and the popular islands such as Koh Samui and Koh Phangan. Remote national parks can have weak signal.
How much data?
Island hopping and backpacking with daily maps, ride apps and messaging usually need 5–10GB over two weeks. Digital nomads staying longer should look at the 20GB-plus plans.
Setting up
Install the eSIM on Wi-Fi before your flight, switch it on after landing, and turn off data roaming on your home SIM. Validity starts at first connection in Thailand.

Quick answers
Does my Thailand eSIM work on the islands?
Yes, on the main tourist islands. Coverage can drop at sea and in remote parks.
Can I share data with a hotspot?
Hotspot use is generally allowed on our plans; check the plan card before buying.
Do I need a Thai number for Grab?
Grab works with your existing number — keep your home SIM active for the SMS code and use the eSIM for data.
