Which Thailand eSIM plan fits your trip?

Choose your Thailand eSIM by matching the allowance and validity period to your trip, then compare the selected product details with the local network, band and speed references already shown on this page.

Start with the length of your stay, then allow for navigation, messaging, streaming and work use. Each option below is a plan size that is currently available for this destination.

Short trip

1 GB / 7 days

Best for: A short visit with maps, messages and occasional browsing.

This option pairs the 1 GB allowance with a stated validity period of 7 days.

Usage tip: Save maps before longer journeys and use Wi-Fi for large downloads.

Two-week trip

3 GB / 15 days

Best for: A stay of around two weeks with regular navigation and messaging.

The 3 GB allowance remains available across a stated validity period of 15 days.

Usage tip: Keep automatic app updates and cloud backups on Wi-Fi.

Longer or higher use

10 GB or more / 30 days

Best for: A longer stay or more frequent streaming, video calls or work use.

The 10 GB or more / 30 days profile provides a larger data pool than the short-trip options on this page.

Usage tip: Compare the allowance with your normal phone usage and monitor it during the trip.

Coverage in Thailand

n258 (26 GHz mmWave) deployment is limited to dense urban areas and select venues; B40 (2300 MHz) is widely used for LTE but absent from many international phone models.

How to check mobile coverage in Thailand

The Thailand mobile network source is linked below as a public network reference. Check the places on your itinerary where the source offers local detail, then confirm the network information for the selected eSIM product. The operator table on this page provides the country-level reference, while the selected product details identify which network information applies to your plan.

Accommodation and daily stops

Check your accommodation and the places you expect to visit in Thailand. Indoor reception can differ from an outdoor map, so keep the property Wi-Fi details available as well.

Journeys between stops

Review the full route rather than checking only the arrival city. Save tickets, addresses and maps offline before longer road or rail journeys.

Borders and onward travel

Check the selected product scope for every country on your itinerary. Your Thailand plan and a regional plan may have different included destinations and validity periods.

Phone compatibility in Thailand

Compare your phone with 4G bands B1, B3, B8, B40 and 5G bands n28, n41, n258 in the existing Thailand network table. Support for more of the listed bands gives the phone more options when connecting, while the selected product, location and local network conditions determine the service available.

Set up the Thailand eSIM for your trip

Keep the QR code and installation instructions available offline, and complete each step according to the selected product's instructions.

When validity starts: Validity-start rules can differ by product. Check the selected plan details before installation and travel.

  1. Confirm that your phone is unlocked and supports eSIM before purchase.
  2. Save the QR code or manual installation details somewhere you can reach without mobile data.
  3. Use reliable Wi-Fi to install the profile at the time recommended in the product instructions.
  4. When you are ready to use it, select the travel eSIM for cellular data and apply the stated roaming and APN settings.
  5. Keep roaming disabled on your home line if you want to avoid using its travel data.

How to Get the Most Out of Thailand

Thailand is Southeast Asia's most visited destination for good reason, but a little preparation goes a long way. In Bangkok, use the Grab app for reliable taxis and avoid rush-hour traffic on the roads. The BTS Skytrain is efficient for longer journeys across the city. In Chiang Mai, songthaews (shared red trucks) are a cheap way to get around the Old City. For island hopping between Koh Samui, Koh Lanta and Phi Phi, book ferries a day ahead during high season. Download Google Translate offline; it handles spoken Thai reasonably well and is invaluable at markets or when ordering food. Withdraw cash in larger amounts to minimise ATM fees, and always carry small notes for street stalls. Learn to say 'khob khun krap' (thank you) and smile - it makes every interaction smoother.

Top Attractions to Prioritise

Grand Palace & Wat Phra Kaew, Bangkok - The official residence of the kings of Siam since 1782. Allow at least half a day; the complex includes the famous Wat Phra Kaew, which houses the revered Emerald Buddha. Dress modestly: shoulders and knees must be covered.

  • Wat Arun, Bangkok - A striking temple on the Thonburi River. Go at sunset for the best light and fewer crowds. It is a short ferry ride from central Bangkok.
  • Chiang Mai Old City & Doi Suthep - The moated old quarter is perfect for walking. Doi Suthep, a temple on a hill, offers panoramic views and is best visited early morning to avoid heat.
  • Railay Beach, Krabi - Accessible only by longtail boat from Krabi town. Known for limestone cliffs and clear water. Pack reef-safe sunscreen.
  • Ayutthaya Historical Park - The former capital of Siam, with ruins spread over a large area. Hire a bicycle to cover more ground.
  • Elephant Nature Park, Chiang Mai - An ethical sanctuary where you can observe rescued elephants. Book weeks in advance.

From Bangkok's Grand Palace to the islands of the Andaman Sea, Thailand offers a mix of history and nature. Here, less is more: pick two or three sites per region to avoid burnout.

Must-Try Thai Dishes

Pad Thai - Thailand's most famous stir-fried noodle dish. Variations exist across the country; Bangkok's street stalls serve it with tamarind sauce, while Chiang Mai's version is often milder. Always order with a wedge of lime.

  • Tom Yum Goong - A hot and sour shrimp soup that balances chilli, lemongrass and lime. The best versions are from central Thailand, where the broth is clear and intensely flavoured.
  • Som Tam (Green Papaya Salad) - Shredded green papaya with chilli, lime and fish sauce. A spicy, crunchy palate cleanser. Ask for it 'mai pet' (not too spicy) if you prefer mild heat.
  • Massaman Curry - A mild, coconut-based curry from southern Thailand, often with chicken or fish. Served with rice or roti. Look for stalls in Krabi or Phuket.
  • Mango Sticky Rice (Khao Niao Mamuang) - A dessert of glutinous rice with ripe mango and coconut milk. Popular during mango season (March-June).
  • Khao Soi - A northern Thai curry noodle soup with crispy egg noodles. The definitive version is in Chiang Mai's Old City.

Thai food is built on fresh herbs and bold contrasts. Stick to busy stalls with high turnover for safety.

Best Time to Visit Thailand

From November to February, most of Thailand enjoys cool, dry weather with lower humidity. Temperatures in Bangkok and the northern hills are pleasant for sightseeing. Book accommodation well in advance, as this is peak season for European and Australian travellers.

December and January are the busiest months, especially in Phuket, Koh Samui and Chiang Mai. Prices for flights and hotels rise by 30-50 per cent. March to May is hot season; temperatures in Bangkok and the central plains can exceed 38°C. April is the hottest month but also brings Songkran, Thailand's New Year water festival, which is a unique cultural experience.

The monsoon runs from June to October. The west coast (Phuket, Krabi) receives heavy rain, while the east coast (Koh Samui, Koh Lanta) is drier. If you want lower prices and fewer crowds, consider visiting in May or September, but expect afternoon downpours. Always pack a light rain jacket.

What to Pack for Thailand

Lightweight, breathable clothing is essential. Pack linen or cotton shirts, shorts and a long skirt or trousers for temples. Avoid synthetic fabrics that trap heat. A light jumper or pashmina is useful for air-conditioned buses and evening breezes.

  • High-SPF sunscreen - Thai sun is intense. Use SPF 50+ and reapply every two hours. Reef-safe options are recommended if you plan to swim.
  • Insect repellent - Mosquitoes are active year-round, especially near water and after dusk. Choose a product with DEET or picaridin.
  • Reef-safe flip flops - Essential for beaches and hostel showers. Also pack a pair of comfortable walking sandals or trainers.
  • Small backpack or day bag - For temple visits and day trips. A cross-body bag with a zip is safer in crowded markets.
  • A travel eSIM - Most local SIMs require registration. An eSIM from your provider lets you stay connected instantly. Download the app before you depart.

Most Thai accommodations provide basic toiletries, but bring your own shampoo and moisturiser if you have sensitive skin. Pack a reusable water bottle with a filter; tap water is not safe to drink.

Common questions about travel eSIMs

Answers to the questions travellers most often ask about using an eSIM overseas, from choosing a data plan to setting up before departure. Thailand eSIM

The eSIM connects to AIS, TrueMove H, and dtac. All three cover 4G on bands B1, B3, B8, B40 and 5G on n28 and n41. This means you get broad nationwide access, though mmWave 5G on n258 is limited to dense urban areas and select venues.

Band B40 (2300 MHz) is widely used for LTE in Thailand but absent from many international phone models. If your phone lacks B40, you may experience weaker coverage indoors or in rural areas. Check your device specs before travel.

No. The eSIM only provides coverage within Thailand's borders. Once you cross into Laos, Myanmar, Cambodia, or Malaysia, the connection stops. You would need a separate eSIM or roaming plan for those countries.

Data is not throttled or filtered beyond standard network management. You get full-speed access up to the plan limit. However, Thailand does block certain content by law, such as gambling sites, which may be inaccessible.

Coverage on major islands and in Chiang Mai city is strong thanks to AIS, TrueMove H, and dtac. However, remote mountain trails or small uninhabited islands may have weak or no signal, as networks concentrate on populated areas.

Compare 1 GB / 7 days, 3 GB / 15 days and 10 GB or more / 30 days. Use the shorter profiles for lighter maps and messaging use, then compare the larger allowance for streaming, video calls or work apps.

The start rule is product-specific. Review the selected plan details before installing it so you know whether any action is required before arrival.

Save the QR code, manual installation details, APN guidance and the support instructions supplied with the selected plan.
