Seamless, Sustainable, Smart: eSIM and iSIM Advance Asia’s Connectivity

Southeast Asia is witnessing a surge in tourism, and with it, a growing reliance on eSIMs. Unlike traditional SIM cards, eSIMs eliminate the need for physical cards, allowing users to activate mobile plans remotely through QR codes or mobile apps. This convenience makes eSIMs a preferred choice for tourists who want to avoid roaming fees and stay connected instantly upon arrival.

In Malaysia and Indonesia, popular tourist destinations such as Bali, Jakarta, and Kuala Lumpur are benefiting from eSIM availability.

Seamlessly Connecting Asia

Asia's journey towards seamless connectivity through eSIM technology began in 2017 when China Mobile and NTT DOCOMO developed the world's first multi-vendor eSIM, alongside the Google Pixel 2, the first smartphone with built-in eSIM technology. In 2019, KDDI partnered with IDEMIA to enhance mobile connectivity for Japanese business travelers using IDEMIA’s Smart Connect Platform. By 2023, Dialog Axiata launched Sri Lanka’s first eSIM service, and in 2024, China Unicom collaborated with G+D on eSIM innovation, while Telkomsel introduced eSIM services for Indonesia's local market. With travel eSIM users expected to surpass 215 million by 2028, eSIM technology continues to drive Asia's digital transformation and flexible connectivity across the region.

​The Rise of iSIM: What’s Next?

While eSIMs are gaining momentum, integrated SIM (iSIM) technology is on the horizon. iSIMs are integrated directly into a device’s processor. This innovation reduces space requirements, enhances security, and further streamlines connectivity. As more devices support iSIM in the coming years, consumers can expect even greater flexibility and efficiency.

According to the GSMA, the release of commercial, industry-certified iSIMs—such as those implemented by Qualcomm and Thales, which adhere to the GSMA’s eUICC Security Assurance (eSA) scheme—hold the potential to trigger mass-adoption. GSMA Chief Technology Officer, Alex Sinclair, emphasized that iSIM development, backed by strict industry standards, highlights the power of industry collaboration.

“iSIM increases the opportunity to proliferate cellular capability and satisfies a wider and more diverse market.”

With projections estimating that the iSIM market will grow to 300 million by 2027, this innovation is poised to drive widespread adoption across various sectors. ​

Sustainability in Connectivity

Beyond convenience, eSIMs contribute to sustainability by reducing the reliance on plastic SIM cards. Traditional SIM production and distribution generate significant plastic waste, whereas eSIM adoption lowers the environmental footprint. With governments and corporations increasingly focusing on sustainability, eSIM technology aligns with broader efforts to minimize waste and reduce carbon emissions. Users can switch between plans or carriers through app-based interfaces, avoiding store visits or physical card replacements.

Asian telcos have embraced eSIM sustainability by introducing eco-friendly eSIMs. In 2022, Globe launched Asia’s first eco-SIM, reducing plastic waste by using 100% recycled materials including polystyrene waste from refrigerators, diverting this waste stream from landfills. Yoly Crisanto, Globe’s Chief Sustainability Officer and SVP for Corporate Communications, explained that this approach gave customers the opportunity to step up and choose to live more sustainably.

“In order for us to truly move the needle in the fight against climate change, we all must take on the responsibility to act sustainably.”

More recently, M1 Limited introduced the True 5G Eco SIM, reinforcing its commitment to environmental responsibility.

Smart Moves: IoT and eSIM Expansion

The Internet of Things (IoT) is set to be a major beneficiary of eSIM technology. From smartwatches and connected cars to industrial sensors and healthcare devices, eSIMs offer seamless, remote connectivity.  While the future of eSIM in Asia looks promising, challenges remain. Standardizing eSIM technology across different regions and carriers is essential to achieve seamless cross-border connectivity. Additionally, increasing consumer awareness and ensuring robust cybersecurity measures will be critical.

Asia's telecom sector is evolving with eSIM technology, supporting IoT connectivity and industry transformation. SoftBank's eSIM platform is promoting IoT adoption, while KDDI Digital Life is exploring new ways to enhance connectivity through its Software Development Kit (SDK), which can be applied to travel eSIM services.

Airtel's partnership with Kia India is powering Kia Connect 2.0, enabling eSIM integration, real-time monitoring, and over-the-air (OTA) updates within connected vehicles. Telkomsel is trialing facial recognition for prepaid SIM registration, showcasing advancements in security. eSIMs were also leveraged during the 2018 FIFA World Cup for enhanced safety.

Meanwhile, Thailand’s AIS is transforming the telecom landscape and enhancing customer experiences through eSIM expansion. During his keynote at the World Mobile Congress 2023, AIS Chairman, Allen Lew, emphasized that the expansion of eSIMs and intelligent devices will drive greater market penetration.

Future Outlook

Telecom operators must adapt to a new competitive landscape. With eSIMs making it easier for users to switch providers, carriers will need to prioritize customer experience (CX), offering innovative plans and personalized services to retain loyalty.

For consumers and businesses alike, the convenience, flexibility, and environmental benefits of eSIMs offer a clear glimpse into the future of telecom. By embracing this digital shift, Asia’s telecom sector is not only enhancing connectivity but also paving the way for a smarter, more connected future.
