eSIMs for Thailand – Guide for Tourists & Expats

Thinking of using an eSIM in Thailand? Learn how to activate, register, and compare eSIM plans for tourists, expats, and long-term residents in 2025.

📱 What is an eSIM and Why It’s Perfect for Thailand?

An eSIM (embedded SIM) is a digital SIM that lets you activate a mobile plan without needing a physical card. Most newer phones support eSIM technology — like the iPhone 11 or later, Samsung Galaxy S20+, and Google Pixel.

In Thailand, eSIMs are available from major carriers like AIS, TrueMove H, and Dtac, as well as global providers such as Airalo and Holafly.

✈️ For Short-Term Travelers and Digital Nomads

If you're visiting for a few weeks or months, eSIMs are extremely convenient:

• No need to hunt for SIM shops at the airport

• Activate before arrival via international providers

• Keep your home number active for OTPs and banking

Popular Tourist eSIM Providers:

• Airalo – Offers Thai data plans starting at $4.50

• Nomad – Easy activation via app, good for Asia travelers

• Holafly – Unlimited data plans (but pricey)

• AIS Tourist eSIM – Register via passport at airport counters or AIS app

Most international eSIMs don't require local ID registration, but you’ll have limited service (e.g., no Thai phone number).

🧳 For Expats and Long-Stay Residents

If you're living in Thailand, using an eSIM from a Thai mobile provider has major benefits:

• Local Thai phone number (for Grab, banks, government services)

• Access to monthly plans and unlimited data

• eSIMs tied to your passport registration (mandatory)

You must register your eSIM in-store (just like with a physical SIM) using your passport. Once registered, you can manage your account through their app.

📲 Which Thai Providers Offer eSIMs?

Here are your main options:

• AIS eSIM: Available for prepaid and postpaid users. Visit AIS Shop for activation.

• TrueMove H eSIM: Instant activation at True Shop. Good network coverage in urban areas.

• Dtac eSIM: Offered via Dtac stores, good for budget plans.

For all, you’ll need:

• A phone that supports eSIM

• Possibly Thai address (for postpaid)

💡 How to Activate a Thai eSIM (Step-by-Step)
