Mobile networks in Thailand: operators and coverage
Thailand has two major operators: AIS and True (since its merger with dtac). Both cover Bangkok, Phuket, Krabi, Koh Samui and Chiang Mai well; on smaller islands the signal is weaker. Tourist SIM cards are also sold at the airport, which requires your passport. With an eSIM you are online as soon as you land and do not have to queue.
How much data do I need?
- Messaging, maps and e-mail only: around 0.5–1 GB per week.
- Plus social media and photo uploads: more like 1–2 GB per week.
- Video streaming or a hotspot for your laptop: easily 1–3 GB per day – a larger or unlimited package pays off here.
These are rough guide values; your actual usage depends on apps and video quality. You can see your own usage in your phone settings under “Mobile data”. Many providers let you top up an eSIM if the data runs out.
Unlimited or a data package?
9 of the 9 providers offer unlimited data packages in Thailand. The cheapest per day is travSIM: 30 days for €59.99, i.e. €2.00 per day. “Unlimited” often means the speed is throttled after a certain amount per day, and hotspot use may be restricted. If you stream little, a fixed package is usually cheaper.
How to set up the eSIM
- Check your phone: it must support eSIM and be unlocked (iPhone XS/XR or later, many current Android devices). Under “Settings → Mobile data” or “Connections → SIM manager” you can see whether “Add eSIM” is offered.
- Buy and install the package: ideally at home on Wi-Fi, via QR code or directly in the provider's app.
- Activate on arrival: switch mobile data to the travel eSIM and enable data roaming for that eSIM. Your home SIM can stay active for calls and texts – turn off data roaming on it to avoid extra charges.
When the validity starts is up to each provider: often only with the first connection in the destination country, sometimes at installation. The package details say which applies.
