Asia-Pacific is home to some of the world’s most advanced digital economies, but it is also one of the most fragmented regions in the global telecommunications industry. Within the same region, consumers can move from markets where mobile services are activated instantly through national digital identity platforms to countries where regulatory restrictions continue to limit how digital services can be deployed.

For years, industry observers assumed that the largest mobile markets would naturally become the leaders of the next generation of digital connectivity, and that bigger populations meant larger customer bases, greater investment opportunities, and stronger incentives for innovation. But the findings of the Holafly Global eSIM Index tell a different story, pointing to a region defined by contradictions.

China (#35) and India (#49) possess the largest mobile subscriber bases on the planet but remain well behind smaller countries in eSIM adoption. South Korea (#21) has used regulation to accelerate adoption rather than slow it, while Australia (#11) and New Zealand (#17) are driving digital transformation by shutting down legacy infrastructure. Meanwhile, highly sophisticated markets such as Japan (#13) and Singapore (#18) have discovered that building seamless experiences for residents can sometimes create unexpected barriers for international visitors. Together, these developments reveal a broader truth about the future of mobile technology: success is increasingly determined not by scale, but by simplicity.

When openness beats size

China (#35) and India (#49) together account for more than 2.4 billion mobile connections, making them the two largest telecommunications markets in the world by an extraordinary margin. Conventional industry logic would suggest that these countries should dominate any ranking related to mobile innovation. Instead, both find themselves trailing considerably smaller markets in the global eSIM race: China ranks 35th globally, while India sits even lower at 49th. Meanwhile, Thailand (#4) ranks fourth globally and Malaysia (#9) has secured a place inside the global top ten. Could incoming tourism be one of the factors accelerating adoption in Thailand and Malaysia?

This reversal is particularly striking because neither China nor India lacks investment in digital transformation or mobile network development. Both countries have invested heavily in these areas over the past decade. However, in China, smartphone eSIM adoption remains constrained by a regulatory framework that prioritises control and limits flexibility. Although authorities have begun opening access to smartphone eSIM functionality, restrictions continue to shape how consumers can use the technology. India has taken a similarly cautious approach, introducing measures that have significantly impacted international travel eSIM providers and reduced the openness that has accelerated adoption in other markets.

Thailand’s population, by contrast, represents only a small fraction of either China or India, yet it has emerged as one of the world’s most advanced eSIM markets, achieving approximately 50% device compatibility and securing the fourth position globally. The country’s success demonstrates that scale is no longer the primary determinant of digital leadership. Instead, the winners are the markets that remove obstacles, encourage competition, and make digital services easier to access.

Malaysia and Thailand: Two APAC markets among the global eSIM leaders

Thailand and Malaysia occupy very different positions in the regional economy, yet both have emerged as leaders in eSIM adoption for a similar reason: they have transformed digital convenience into a competitive advantage. In many telecom markets, operators still compete primarily through network coverage, pricing strategies, or handset promotions. However, the cases of Thailand (#4) and Malaysia (#9) show an evolution beyond these traditional battlegrounds, with competition increasingly focused on delivering a seamless digital experience.

Consumers have become accustomed to services that operate instantly. Banking, shopping, entertainment, and transportation have all undergone a process of simplification in which physical interactions have been replaced by software-driven experiences. Telecommunications is now undergoing the same transition, and eSIM technology represents more than a new way of activating a mobile line; it reflects a broader expectation that access to services should be immediate, flexible, and largely invisible to the user.

Thailand illustrates the power of this trend, as the country’s highly competitive operator environment has created strong incentives to reduce friction throughout the customer journey. Malaysia has followed a similar trajectory, supported by an increasingly dynamic market structure and a growing focus on digital experiences. The lesson extends far beyond telecommunications. Consumers are increasingly rewarding organisations that remove complexity rather than add features, and in that environment, simplicity itself becomes a competitive advantage.

When regulation becomes an adoption engine: the case of South Korea

Regulation is often portrayed as a force that slows technological innovation, but the case of South Korea (#21) demonstrates that the opposite can also be true. Rather than limiting adoption through additional controls, regulators actively intervened to encourage consumers to embrace eSIM technology by requiring operators to make digital profiles cheaper than traditional physical SIM cards. It might seem like a relatively simple policy decision, but it fundamentally altered the economics of adoption.

Historically, consumers have often been asked to pay more for newer technologies. Whether through activation fees, premium services, or hardware upgrades, innovation frequently arrives with an additional cost. South Korea, however, reversed that pattern by ensuring that the digital option was also the more affordable one, aligning consumer incentives with broader digital transformation goals. The result has been one of the highest levels of eSIM-compatible device penetration in the region, reaching approximately 60%.

More importantly, the Korean experience offers a valuable lesson about the evolving role of government in digital markets. Policymakers are increasingly recognising that digital infrastructure is not solely a commercial issue but a strategic one. The ability to accelerate adoption can influence economic competitiveness, technological leadership, and consumer behaviour. South Korea’s approach suggests that governments do not necessarily need to choose between regulation and innovation. Under the right conditions, regulation itself can become one of the most effective tools for driving adoption.

Can 3G shutdowns accelerate eSIM adoption?

Australia (#11) and New Zealand (#17) are pursuing a very different path toward digital transformation. Rather than focusing primarily on promoting eSIM technology, both countries have accelerated adoption by systematically removing the infrastructure that supports older technologies. The gradual shutdown of legacy 3G networks is creating a powerful incentive for consumers to upgrade their devices, bringing millions of users into an ecosystem where eSIM compatibility is increasingly standard.

This approach reflects a broader reality that extends well beyond telecommunications. Organisations often devote significant resources to promoting new technologies while continuing to support legacy systems indefinitely. The result is a prolonged transition period during which adoption remains slower than expected. Australia and New Zealand have chosen a different strategy. By reducing reliance on outdated infrastructure, they are effectively compressing technology replacement cycles that might otherwise take years to unfold.

The impact is already visible. Australia has reached approximately 50% device compatibility, while New Zealand has climbed even higher to around 55%. More importantly, both countries demonstrate that transformation is often driven not by introducing something new, but by removing something old. In a digital economy increasingly shaped by software-based services, the willingness to retire legacy infrastructure may prove just as important as the willingness to invest in emerging technologies.

Can the most advanced systems be too complex?

If China (#35) and India (#49) illustrate the consequences of regulatory control, Japan (#13) and Singapore (#18) reveal a more subtle challenge. Both countries are among the most digitally sophisticated societies in the world, with highly developed mobile ecosystems, digital identity systems deeply integrated into everyday life, and consumers benefiting from streamlined onboarding experiences that many countries still struggle to provide. However, these same strengths can create unexpected complications for international visitors.

For residents, systems such as Singapore’s Singpass can make mobile activation almost effortless; authentication happens quickly, onboarding is streamlined, and security standards remain exceptionally high. For tourists and non-residents, however, the experience can be very different. Those without access to these national identity systems often encounter additional verification requirements, creating a level of friction that local consumers never experience.

Yet despite these challenges, both countries continue to rank among APAC’s strongest eSIM markets, as their sophisticated digital infrastructure, high levels of device compatibility, and mature mobile ecosystems have enabled them to maintain leading positions in the rankings.

But this still creates one of the most interesting paradoxes in the global eSIM market, as despite having some of the most efficient digital ecosystems for residents, they can make access more difficult for visitors. Japan (#13) and Singapore (#18) demonstrate that strong digital identity frameworks can be a major driver of domestic eSIM adoption while simultaneously creating new onboarding challenges for non-residents. The challenge facing advanced digital economies is no longer simply how to create secure systems. It is how to create systems that remain secure while also accommodating increasingly global and mobile populations.

Can eSIM go beyond the smartphone?

Much of the global conversation around eSIM technology focuses on smartphones, smartwatches, and consumer devices. New Zealand suggests that this perspective may be far too narrow. While the consumer market continues to grow, some of the most significant opportunities are emerging in sectors that have little to do with traditional mobile usage.

If we look at agriculture, logistics, remote monitoring, and industrial IoT, these sectors are increasingly becoming major drivers of eSIM deployment. New Zealand has positioned itself as one of the world’s most interesting testing grounds for these applications, where eSIM technology is being integrated into agricultural equipment, remote sensors, and connected infrastructure that operate far beyond the reach of traditional consumer devices.

The value proposition is fundamentally different. Instead of improving convenience for an individual user, eSIM enables machines to switch networks remotely, maintain connectivity across challenging environments, and reduce operational complexity at scale.

This development expands the conversation beyond consumer adoption metrics and opens the door to the long-term significance of eSIM, which may not be defined by how many smartphones support the technology, but by how deeply it becomes embedded in the infrastructure that powers modern economies. APAC’s experience suggests that the future of digital mobility extends far beyond personal devices, and the next wave of growth may come from industries that view eSIM not as a consumer feature, but as critical infrastructure.

What happens next in the APAC region?

The APAC region reveals a telecommunications industry in transition, where some markets are accelerating adoption through competition, while others are relying on regulatory incentives, infrastructure modernisation, or digital identity systems. At the same time, several of the world’s largest mobile markets continue to demonstrate how regulatory friction can slow adoption despite enormous potential. What emerges from these contrasting approaches is a remarkably consistent conclusion: technology alone is rarely the deciding factor.

The countries leading the next phase of eSIM adoption are not necessarily those with the largest populations or the biggest telecom operators. They are the ones making digital access easier, faster, and more intuitive. As consumers increasingly expect services to function instantly and seamlessly across borders, reducing friction is becoming one of the most valuable competitive advantages a market can possess.

The APAC story ultimately challenges one of the industry’s oldest assumptions. For decades, scale was considered the defining measure of telecommunications success. Today, the evidence points in a different direction. In the emerging era of digital mobility, the markets most likely to lead are not the biggest. They are the ones that make technology disappear into the background, transforming access into something so simple that users barely notice it at all.

As governments, operators, and technology providers continue to shape the future of digital services, APAC is becoming a real-world testing ground for competing approaches to adoption. The region’s experience suggests that the next generation of telecom leaders will not be defined by the size of their markets, but by their ability to remove barriers between consumers and the digital experiences they increasingly expect.
