In 2025, True Corporation celebrated a significant achievement with the successful completion of the One Network project. This accomplishment brought about complete network integration between True and dtac, strengthening Thailand’s telecommunications infrastructure considerably. The project resulted in a robust digital network with broad coverage across the nation, enhanced performance, and a significantly improved mobile experience for customers of both brands.
True Corporation’s CEO, Mr. Sigve Brekke, emphasized the project’s success lay not merely in merging towers or upgrading equipment. The One Network project represented a full-scale modernization of the network, encompassing strategic planning, digital infrastructure enhancement, and the integration of new technologies into a single network. The resulting integrated network supports daily usage demands and provides a robust foundation for future technologies. This achievement is a testament to the dedication of the network specialists and their close collaboration with global technology partners to deliver high-quality connectivity nationwide.
From 2023 to 2025, True Corporation focused on continually increasing network capacity to cater to growing usage demands, such as those encountered at concerts, major events, and areas with heavy user traffic. The corporation successfully merged 5G and 4G technologies, leading to an average nationwide network capacity increase of 1.37 times. The capacity of the 5G network nearly doubled, reflecting efficient spectrum utilization and network management. These enhancements resulted in faster, smoother, and more reliable connectivity, even in densely populated areas.
The One Network project resulted in significant improvements in both network coverage and signal quality. This was especially noticeable for former dtac customers. Prior to the integration in 2023, dtac’s 5G coverage stood at 47%, while True’s was at 83%. By 2025, the combined 5G coverage reached 94% nationwide, with 4G coverage at 99%. The average nationwide 5G and 4G signal quality improved by 76%, with the most significant enhancements seen in provinces with high usage.
True Corporation also undertook efforts to improve 5G and 4G network quality across major tourist destinations nationwide. This ensured seamless connectivity during the peak New Year travel period. Coverage was expanded to include natural attractions, leading tourism cities, economic hubs, and national landmarks across all regions. In Bangkok, the network covered key tourist, retail, and lifestyle districts, supporting heavy digital usage and communications by residents and visitors, as well as major countdown venues.
Through the One Network project, True Corporation strives to provide smoother connectivity during peak holiday periods, reduce congestion in densely populated areas, and enhance speedy, reliable digital experiences that support tourism and economic activity across the country.
The project’s success implies more than just network integration. It represents a transformation towards a smarter, more efficient network that elevates Thailand’s telecom standards and ensures seamless connectivity for True and dtac customers in all situations.
