The carrier completed full network integration with the former dtac infrastructure in October 2025, enabling spectrum pooling across 1,350 MHz of total spectrum — the broadest multi-band portfolio in the country — including the newly acquired 2300 MHz and 1500 MHz bands secured at auction in June 2025.

Network Coverage And Performance

True Move H covers 93% of Thailand's population with 5G service and achieves over 99% coverage in Bangkok and the Eastern Economic Corridor (EEC). The carrier completed its One Network integration project in October 2025, combining former True Move H and dtac tower infrastructure — resulting in a 23% increase in tower access for True Move H customers and a 72% increase for dtac customers, according to True Corporation's Q3 2025 Quarterly Bulletin published November 2025.

Geographic 5G deployment concentrates in Bangkok, Chiang Mai, and Phuket at the highest density, with reliable highway corridor coverage extending to major provincial capitals including Khon Kaen, Hat Yai, and Udon Thani. Rural northern and deep-southern regions show patchier signal compared to urban zones, as noted in independent user comparisons published in 2025.

4G And 5G Availability

True Move H achieves 74.2% 5G Availability — the highest figure among all Thai carriers — meaning 74.2% of True Move H users access a 5G connection a majority of their time on the network, according to Ookla Speedtest Intelligence for H1 2025. The carrier's 4G LTE network provides near-universal urban and suburban coverage across all 77 Thai provinces.

True Move H's spectrum portfolio includes 5G NR on Band n78 (2600 MHz / 2500–2690 MHz TDD), supported by Dynamic Spectrum Sharing (DSS) technology enabling flexible 5G and 4G co-deployment. The 2600 MHz band utilises full 90 MHz bandwidth following the One Network project, while the newly acquired 2300 MHz band (70 MHz) and 1500 MHz band (20 MHz) secured in June 2025 enhance both 5G performance and 4G capacity, according to the True Blog spectrum announcement published June 29, 2025. The 4G LTE layer operates across 700 MHz (Band 28), 850 MHz (Band 5 and n26), 900 MHz (Band 8), 1800 MHz (Band 3), and 2100 MHz (Band 1).

Strongest 5G performance concentrates in three regions: Bangkok (including EEC), Phuket, and Chiang Mai, where median 5G download speeds reach 100–200 Mbps in optimal conditions, according to independent testing published in 2025.

Speed Test Results

True Move H delivers a Speedtest Connectivity Score of 73.77 for H1 2025 and a score of 76.84 for Q3–Q4 2025, placing it second in Thailand behind AIS (76.05 in H1 2025 and 78.18 in Q3–Q4 2025), according to Ookla Speedtest Award reports published in 2025.

True Move H key advantages and disadvantages based on 2025 network data

• Broadest Spectrum Portfolio: True Corporation holds Thailand's most comprehensive 8-band spectrum portfolio at 1,350 MHz total, including dedicated 5G NR on 2600 MHz, 2300 MHz, and 1500 MHz bands, following the June 2025 spectrum auction, according to the True Blog announcement published June 29, 2025.

• Nationwide 5G Population Coverage At 93%: The combined True-dtac network reports 93% nationwide 5G coverage as of February 2025, with over 99% in Bangkok and the EEC, according to OpenSignal Thailand Mobile Network Experience 5G Report published June 2025.

• Largest Mobile Subscriber Base In Thailand: True Move H leads Thailand in total mobile subscriptions at 46.9 million as of Q3 2025, and recorded 15.5 million 5G subscribers — the highest 5G subscriber count among Thai operators — according to True Corporation's Q3 2025 Quarterly Bulletin published November 2025.

• Strong EBITDA Efficiency Post-Merger: True Corporation reports an EBITDA margin of 65.3% and EBITDA of 27 billion THB, reflecting cost discipline and operational scale following the True-dtac merger, according to The Nation Thailand analysis published January 2026.

Disadvantages

• Second-Place Overall Speedtest Score: True Move H scores 73.77 (H1 2025) and 76.84 (Q3–Q4 2025) on Ookla's Speedtest Connectivity Score, trailing AIS at 76.05 and 78.18 respectively in both periods, according to Ookla Speedtest Award reports published in 2025.

• Patchy Rural Coverage In Northern And Deep-South Regions: Independent user assessments published in 2025 identify weaker signal quality in remote northern highlands and deep-southern provinces compared to urban-centric networks, making AIS the preferred choice for rural-heavy travel itineraries.

• True App Performance Issues: User reviews on Google Play (December 2025) and the App Store report slow loading times of 15–25 seconds on startup, login failures, and difficulties redeeming True Points, indicating app stability gaps despite the 4.3-star aggregate rating from 295,000 reviews.

• Subscriber Base Decline In 2025: True Move H's mobile subscriber base declined 4.8% year-on-year by Q3 2025, dropping from 49.4 million (end 2024) to 46.9 million, driven by biometric registration requirements and a one-time network outage incident, according to True Corporation's Q3 2025 Quarterly Bulletin published November 2025.

True Move H Vs Competitors

Thailand's mobile market operates as an effective duopoly between True Move H and AIS, with National Telecom (NTPC) holding a distant third position and facing structural challenges. AIS maintains revenue leadership with a 49% mobile revenue market share as of end 2024, while True leads in total subscriber volume, according to Thailand digital market analysis published in 2025. NTPC's ongoing financial discussions with AIS and True signal a potential shift toward a wholesale or infrastructure-focused role rather than direct retail competition.

True Move H suits subscribers who prioritise 5G availability and total coverage breadth, particularly in Bangkok, the EEC, and tourist destinations including Phuket and Chiang Mai. AIS delivers a marginally higher overall Speedtest score and leads in revenue market share, making it the preferred network for users who prioritise raw speed consistency in urban environments. National Telecom serves a niche role for specific government-linked or budget requirements, with limited 5G infrastructure.
