Compare Thailand eSIM Plans

The Thailand eSIM has five options: TrueMove 15GB (7 Days) at A$15.90, TrueMove 50GB (10 Days) at A$16.90, DTAC 35GB (7 Days) at A$16.90, DTAC Unlimited (10 Days) at A$22.90 and DTAC Unlimited (15 Days) at A$35.90. The DTAC 35GB (7 Days) and DTAC Unlimited (10 Days) allowances are a promotion for eSIMs activated by 31 December 2026; after that date these two options revert to 15GB and 50GB respectively. Prices are in Australian dollars and convert automatically if you shop in another currency.

Which Thailand eSIM Should I Choose?

One week in Bangkok and the beach: TrueMove 15GB (7 Days)

For a week split between Bangkok and Phuket, Krabi or Koh Samui, the Thailand eSIM TrueMove 15GB (7 Days) option at A$15.90 covers maps, ride-hailing, restaurant searches and daily photo uploads. It runs on TrueMove H with hotspot allowed and no ID requirement, and its Thai number receives SMS verification codes for local apps; making voice calls needs a top-up.

Ten days and heavy use: TrueMove 50GB (10 Days)

If you stream, work remotely or share your connection with a partner, the TrueMove 50GB (10 Days) option at A$16.90 gives you a large allowance for only a little more than the 7-day plan. It suits a Bangkok, Chiang Mai and islands itinerary where you rely on your phone all day.

You want to make and receive local calls: DTAC Unlimited (15 Days)

The DTAC Unlimited (15 Days) option at A$35.90 is the one to choose if you need voice. It includes a local Thai number, unlimited local calls within Thailand, free incoming calls, and 30 minutes of calls to Mainland China, Hong Kong, Macau, Taiwan, India, South Korea and Vietnam, alongside unlimited data on DTAC. That makes it practical for calling hotels, drivers, dive shops and clinics that do not use messaging apps. See more options with voice on our travel eSIMs with calls page.

Thailand as part of a longer route: Asia Explorer or Global Explorer

For a trip that continues to Vietnam, Malaysia, Singapore or Japan, the Asia Explorer eSIM 20GB Data (15 Days) plan is A$25.90. If your journey extends beyond Asia, the Orange Global Explorer eSIM offers 20GB (30 Days) for A$43.90 with Thailand in its full 20GB zone.

Thailand Network Coverage: TrueMove H and DTAC

Thailand's mobile market is led by AIS and True Corporation, which runs the TrueMove H and DTAC brands following their merger. Many travellers search for an AIS Thailand eSIM, so to be clear: the Thailand eSIM plans on this page connect to TrueMove H or DTAC, depending on the option you select, and not to AIS. The Asia Explorer eSIM uses TrueMove in Thailand, and the Orange Global Explorer eSIM roams on Orange partner networks.

Both TrueMove H and DTAC offer nationwide 5G/4G LTE coverage, with availability varying by area. In practice that means Bangkok, Chiang Mai, Phuket, Krabi and the main tourist islands such as Koh Samui and Koh Phangan. Signal is generally available on Bangkok's BTS Skytrain and MRT lines. Expect weaker coverage on ferry crossings between islands, in national parks, on mountain roads in the far north and on the smallest islands, where a single tower may serve a whole beach. Our guide to mobile connection after the True and DTAC merger looks at how the networks perform from coast to coast.

Travelling Beyond Thailand?

The Thailand eSIM works in Thailand only, so it will stop at the border with Malaysia, Cambodia, Laos or Myanmar. Two multi-country options include Thailand. The Asia Explorer eSIM covers 12 destinations on one QR code: Thailand, Vietnam, Malaysia, Singapore, Indonesia, Hong Kong, Macau, Taiwan, Japan, South Korea, Australia and New Zealand. The Orange Global Explorer eSIM covers more than 180 countries and regions, including Thailand, Cambodia, Laos and Vietnam in its 20GB zone, and comes with a French number.

Prefer one plan per country? See our Vietnam eSIMs, Cambodia eSIMs, Laos eSIMs and Malaysia eSIMs, or compare regional plans in the Southeast Asia eSIM collection.

How It Works

1. Buy online. Choose your network, data size and validity. The QR code is delivered by email; orders placed after 1:00 AM AEST are sent from 9:00 AM AEST.
2. Install on Wi-Fi when you are ready to travel. This plan behaves differently from most travel eSIMs: service starts on the first QR code scan, even if you are outside Thailand. Scan it just before you fly or on arrival using airport or hotel Wi-Fi, not days in advance. An unactivated QR code is valid for 90 days after purchase.
3. Land and connect. Switch on the eSIM line, enable data roaming for it and set it as your mobile data line. Your 7, 10 or 15 days run from activation. No ID or passport registration is required.

Step-by-step instructions are in the Thailand TrueMove eSIM user guide and the DTAC plan FAQ. Our Melbourne-based support team is available 16 hours a day by live chat and email. The Asia Explorer eSIM starts on first network connection in any of its 12 destinations, and the Orange Global Explorer eSIM starts once it is installed and connects to a network, so install those just before you travel or after you arrive as well.

Thailand eSIM vs Roaming on Your Home Plan

Roaming on your home plan is the low-effort option, but it is normally billed per day or per megabyte, often with a small daily allowance and slower speeds once you pass it. Over a two-week holiday the daily fees add up regardless of how much you actually use, and background app activity can trigger a charge on days you barely touch your phone.

A prepaid Thailand eSIM is a one-off purchase with a known allowance and end date. Your home SIM stays active in the phone for bank verification codes and urgent calls, while the eSIM carries your data on a Thai network. You also gain a Thai number that receives SMS, which roaming on a foreign number does not give you, and the DTAC Unlimited (15 Days) option adds local calls.

Tips for Using an eSIM in Thailand

• Do not scan the QR code early. Validity starts at the first scan, so wait until departure day or arrival.
• Check that your phone is unlocked and supports eSIM. Dial *#06#: a 32-digit EID means the device is compatible. Our eSIM compatibility list has model details.
• Ride-hailing apps such as Grab and Bolt are widely used in Bangkok, Chiang Mai and Phuket, and work well on mobile data for airport pickups and late-night rides. The Thai number on your eSIM can receive the SMS code needed to register a Grab account.
• LINE is the main messaging app in Thailand. Many guesthouses, tour operators and restaurants take bookings through it.
• Island hopping involves ferries and piers with patchy signal. Save tickets, maps and accommodation details offline before you leave the mainland.
• Hotspot is allowed on every Thailand eSIM option, which helps when hotel Wi-Fi is slow. Tethering a laptop uses data quickly, so pick 50GB or Unlimited if you plan to work online.
• Street food stalls and markets are mostly cash-based. Use your data to find an ATM or currency exchange.
