So, you’re getting ready for an unforgettable trip to Southeast Asia and you’re wondering how to stay connected while you’re there. You’ve probably started looking into Thailand SIM card, checking prices, how to activate one, and what other options are available, because no one wants to be without internet while traveling.
In our complete guide, you’ll learn everything you need to know about physical SIM cards, digital alternatives like eSIMs for Thailand, and what to consider to pick the best option for your trip.
Which SIM card should you get in Thailand?
There are three main mobile network providers in Thailand:
AIS – Advanced Info Service
Widely considered the best for coverage and speed. Ideal if you’re planning to explore rural areas or lesser-known islands.
Pros: excellent coverage, fast 5G connection, reliable signal
Cons: slightly higher prices than competitors
DTAC – Total Access Communication
A solid alternative to AIS, with slightly less coverage in rural areas but very competitive rates.
Pros: budget-friendly plans, SIM cards are easy to find locally
Cons: weaker signal outside major cities, 5G not always available
True Move H
Possibly the best balance between coverage, price, and signal quality. Their tourist SIMs are widely available at airports and convenience stores.
Pros: strong signal in urban areas
Cons: unstable coverage in remote areas and islands
Thailand eSIM: the digital alternative
Wondering what an eSIM is and how it works?
An eSIM (embedded SIM) is a virtual SIM card built directly into your smartphone. You don’t need to insert anything physical, just scan the QR code you receive by email after purchasing (check your phone’s compatibility here).
It’s a great option for travelers who want to skip the airport queues or avoid wasting time hopping from shop to shop looking for the best deal.
Why choose a Thailand eSIM?
Beyond convenience, what makes eSIMs such a smart choice over traditional SIM cards?
- Instant activation: activate your data plan before you leave or as soon as you land, your internet will be ready right away
- No risk of losing it: since it’s virtual, there’s nothing to lose, and you won’t have to remove your usual SIM card
- Flexibility: choose exactly the data plan you need and even install multiple eSIMs on your phone (just remember only one can be active at a time)
- No roaming fees: you’ll connect directly to a local Thai network, avoiding international roaming charges
