A Region on the Rise
Why These Projects Matter
With over 650 million people spread across diverse geographies, ranging from megacities to remote islands. Southeast Asia faces unique challenges in digital infrastructure deployment. Inequality in internet access, inadequate broadband penetration, and inconsistent digital policies make it essential for countries in the region to embark on large scale initiatives.
Telecommunication megaprojects not only bridge the urban rural divide but also power national economic strategies such as Indonesia’s “Digital Nation 2045,” Malaysia’s “MyDIGITAL,” and Vietnam’s “National Digital Transformation Program.”
Indonesia, Palapa Ring and SATRIA
Indonesia, with its 17,000 islands, faces enormous connectivity challenges. The Palapa Ring Project, completed in 2019, was a groundbreaking $1.3 billion initiative to build 12,000 km of fiber optic cable connecting remote islands. It laid the groundwork for future digital expansion and enabled improved services for education, health, and commerce in underserved areas.
The network now links remote islands. It helps schools, clinics, and small businesses. Next is the SATRIA satellite, launched in 2023. It connects 150,000 public sites like schools and hospitals.
Malaysia, JENDELA and 5G Plans
Malaysia has taken a bold step in its digital journey through the JENDELA program (Jalinan Digital Negara), a national initiative launched in 2020 to improve fixed and mobile broadband quality. It aims to cover over 98% of populated areas with 4G and prepare the country for a full scale 5G rollout.
The government formed Digital Nasional Berhad (DNB) to build a single 5G network. This model cuts costs and avoids duplicate work. Big cities already have 5G service today.

Vietnam, Moving Toward 5G
Vietnam is quickly becoming a digital powerhouse in ASEAN. Its government is investing heavily in national fiber optic backbones, data centers, and 5G technology. Vietnam aims to achieve nationwide 5G coverage by 2030 and is promoting the use of locally developed 5G technologies through state-owned telecoms like Viettel.
In 2023, Vietnam opened a $200 million national data center. It supports cloud services, AI, and digital government systems. By 2030, the country wants full 5G coverage.
Thailand, The EEC and Digital Growth
Thailand Eastern Economic Corridor (EEC) is more than just an industrial zone, its also a key site for digital innovation. The Thai government is investing in 5G networks, smart cities, and submarine cable stations in the area to attract tech investments and boost connectivity with global markets.
The country has also partnered with international firms to expand data centers and cloud services, recognizing the growing demand for digital infrastructure in supporting AI, fintech, and IoT applications.
Philippines, Broadband and Private Investment
The Philippines faces slow internet and weak coverage. To fix this, the government launched the National Broadband Plan.
The plan includes fiber backbones, satellite access, and shared telecom towers. Big companies like PLDT and Globe also invest in 5G and undersea cables.
Cross Border Projects and ASEAN Goals
Beyond national projects, Southeast Asia is also witnessing a rise in cross-border telecommunication infrastructure. Initiatives like the ASEAN Digital Masterplan 2025 aim to harmonize digital policies, expand inter country fiber optic links, and create regional data governance standards.
Undersea cables such as the Asia Direct Cable (ADC) and SEA-H2X connect multiple ASEAN nations to global internet hubs, enhancing redundancy, speed, and reliability. These megaprojects are vital for the region’s resilience and digital sovereignty.

Challenges to Telecom Growth
Despite their ambitious goals, telecommunication megaprojects in Southeast Asia face significant challenges. Ranging from geographic barriers, funding issues, regulatory complexities, to cybersecurity threats. Political instability in some nations can also slow down implementation and raise risks for investors.
Moreover, coordination among government agencies and private stakeholders remains a persistent issue. A regional framework for telecom infrastructure governance could be key to unlocking more sustainable progress.
Looking Forward, Equity and Innovation
Looking forward, Southeast Asia focus must shift toward digital equity. Ensuring that rural, marginalized, and low-income populations also benefit from connectivity. Innovation in low-earth orbit (LEO) satellites, AI driven network management, and green telecom infrastructure will play a vital role.
With a shared commitment to digital transformation, collaboration among ASEAN nations, tech companies, and global institutions can propel Southeast Asia into a new era of smart, inclusive, and resilient connectivity.
