ANALYSIS: eSIMs in laptops: why hasn’t this no-brainer taken off yet?

Despite the rapid adoption of eSIM in smartphones, laptops have yet to catch up. Hamish White, CEO of telecom software provider Mobilise, explains why laptop makers, app developers, and mobile providers are missing a golden opportunity and how smart integration could unlock massive new value.

It’s a surprising gap, especially as remote work surges and digital nomads demand always-on connectivity.

eSIMs, are rapidly replacing traditional SIM cards with a built-in, programmable alternative. In 2024, there were close to 600 million smartphone eSIM connections globally — over three times more than in 2022. eSIM technology offers a range of benefits for mobile users, including flexibility to change providers and global connectivity during international travel.

Laptops users also stand to benefit from eSIM implementation, especially in the case of remote workers. With the number of digital nomads across the world expected to reach 60 million by the end of the decade, eSIMs offer reliable and secure connectivity for laptops, which have historically depended on external Wi-Fi networks or mobile tethering for internet access. Instead, using eSIMs, remote workers can keep connected wherever there is cellular coverage, without depending on potentially unsecure or poor public Wi-Fi.

Yet, eSIM integration in laptops remains low, largely due to compatibility challenges when adding eSIM into existing applications and devices.

So, is eSIM integration worth it for service providers, and how can the implementation process be made easier?

The case for eSIM integration

Although disappointing from an end-user perspective, the lack of eSIM adoption presents an opportunity for businesses to differentiate themselves by harnessing the technology.

Take for example, streaming services providers. Although many subscribers choose to watch video content while travelling, their experience can be poor due to patchy or unavailable Wi-Fi. By integrating eSIM connectivity into their app, streaming services can offer a smoother watching experience.

Any company with a laptop app can benefit from integrating eSIM. For example, security apps can guarantee access to reliable connectivity for real-time updates and monitoring, while gaming apps can ensure enhanced responsiveness for their users. Furthermore, offering integrated eSIM connectivity can boost user engagement and retention, fostering customer loyalty.

Integrating eSIM technology at the hardware level also means PC manufacturers can offer a streamlined independent computing experience by eliminating user reliance on third-party solutions such as mobile tethering or USB dongles.

Some PC manufacturers are already beginning to embrace the technology, with HP recently launching a multi-carrier 5G eSIM laptop that enables automatic switching to the strongest available network. Currewntlmjy it is only available in the US, with worldwide deployment to begin in late 2026 

Manufacturers can also provide a native eSIM management app, making network selection and activation easier for users. This feature can make their devices more appealing, especially to professionals and frequent travellers.

The advantages of laptop eSIMs are not just limited to newer players in the market. For mobile eSIM providers, expanding their offering beyond smartphones to include laptops opens new revenue opportunities.

Remote workers, business travellers and digital nomads require reliable connectivity on the go, making laptops a natural extension of eSIM services. By catering to this market, providers can generate additional income with minimal effort.

SDK support

Given the perceived complexity of integrating eSIM technology into laptops, how can service providers go about providing these benefits to their customers?

Mobilise offers a Windows software development kit (SDK) that simplifies eSIM integration for customers across these segments. The SDK is fully compatible with eSIM-enabled laptops running Windows 10 and above, allowing businesses to incorporate seamless connectivity into their applications and devices without extensive development effort.

For app developers, the SDK ensures quick and easy integration of eSIM management features, enabling them to offer a more connected experience to users. Mobile eSIM providers can expand their reach beyond smartphones with minimal investment, opening up new revenue streams.

Meanwhile, PC manufacturers will be able to incorporate native eSIM capabilities effortlessly, resulting in enhanced product value and competitiveness. Businesses can take advantage of the growing demand for on reliable and secure laptop connectivity, improving customer satisfaction and standing out in an increasingly competitive market.
