True (Truemove H) vs Other Thailand Mobile Operators

Based on the June 2025 Opensignal Report for Thailand, the competitive landscape has changed significantly following the True-dtac merger and network upgrades. TrueMove H has shifted its dominance from speed metrics to coverage and accessibility, while its merged partner, dtac, now leads in multimedia performance.

Download Speed Experience (Joint Winner): TrueMove H has significantly improved its throughput, now sharing the award for Download Speed Experience with dtac. This makes it a top-tier choice for heavy data users and travelers.

Availability (Joint Winner): TrueMove H is a Joint Winner in the Availability category. Users on the TrueMove H network can find a consistent signal as reliably as those on AIS or dtac, covering the vast majority of populated areas in Thailand.

Shift in Video & Upload Performance: Unlike the 2023 report, TrueMove H no longer holds the outright win for Video or Upload speeds.

• Video Experience: The crown for Video Experience has passed to its sister brand, dtac, which is now the sole winner in this category.
• Upload Speed: AIS has taken the lead as the sole winner for Upload Speed Experience.

5G Integration: While TrueMove H shared several awards, its integration with the broader True-dtac network has resulted in a more robust 5G footprint, contributing to its joint victories in overall speed and availability.

True (TrueMove H) Tourist Plans: SIM Card vs eSIM

TrueMove H – now part of True Corporation after the 2023 merger with dtac — is Thailand’s largest mobile operator with 99% population coverage and over 51% market share. For tourists, that means a reliable signal whether you’re in Bangkok’s shopping malls, on a Phuket beach, or in a remote national park.

There are two ways to get a TrueMove H connection for your trip:

TrueMove H tourist SIM card is a physical nano-SIM you collect after landing. You can find it at True/dtac counters at all major international airports, True 5G stores near BTS and MRT stations, and most 7-Eleven branches across Thailand. Passport registration is required at the point of purchase. The “Thailand Tourist Infinite” plans start at 449 THB for 8 days and include unlimited 5G data, unlimited local calls, and exclusive “True Privileges” discounts at Grab, 7-Eleven, and airport restaurants.

TrueMove H eSIM runs on the identical network with the same plans — the only difference is delivery. Instead of a physical card, you get a QR code sent to your email. Scan it before your flight, and your phone connects to the TrueMove H network the moment you land. No queue at the airport counter, no passport registration at the store.

	TrueMove H Tourist SIM	TrueMove H eSIM
Where to buy	Airport counter, True/dtac shop, 7-Eleven	Online — before or after arrival
Passport required	Yes — register in person	No
When you get connected	After arriving and queuing	Before you board the plane
Plans & pricing	8-day 449 THB · 15-day 699 THB · 30-day 1,199 THB	Same plans + additional options
Data	Unlimited 5G at max speed	Unlimited 5G at max speed
Local calls	Unlimited to all Thai networks	Unlimited to all Thai networks
True Privileges discounts	Included	Included
Device compatibility	Any unlocked phone	Requires eSIM-compatible device
Risk of loss / damage	Yes (physical card)	No

Which should you choose? If your phone doesn’t support eSIM — common with older Android models or budget phones — pick up a physical SIM at the airport. TrueMove H counters are clearly signed at Suvarnabhumi, Don Mueang, Phuket, and Chiang Mai airports. If your phone supports eSIM (iPhone XS and later, Google Pixel 3+, Samsung Galaxy S21+), the eSIM route saves 15–20 minutes of queuing and gets you connected before your flight even lands.

To use an eSIM in Thailand, you will need a compatible device that supports eSIM technology, such as the latest iPhones, Google Pixel devices, and some Samsung Galaxy devices. You will also need to check with your mobile operator to ensure that they offer eSIM plans and that your device is compatible with their network.
