  • eSIMs offer a significantly more strea­mlined and efficient activation process co­mpared to traditional physical SIM ca­r­ds. Unlike physical SIM cards that re­quire manual insertion and activation procedures, eSIMs can be activated re­motely and seamlessly through a QR co­de scan. This simplified process typically takes a mere 15 minutes for the eSIM to register with the mobile network and establish connectivity.
  • eSIMs offer a remarkable advantage ov­er traditional physical SIM cards by enabling the storage of multiple network profiles within a single eSIM. This innovative feature eliminates the need for us­ers to carry multiple physical SIM cards, reducing the inconvenience of manually switching between them. With eSIMs, users can seamlessly switch between different mobile network providers directly from their device’s network settings.
  • eSIMs also enable users to switch to lo­cal operators easily while travelling. Travellers can effortlessly switch to local mobile network providers directly from their devices, instead of visiting telecom stores or activating old SIM ca­rds. This seamless connectivity en­sures un­interrupted communication and acc­ess to essential mobile services while travelling abroad.
  • The adoption of eSIM technology pre­sents a compelling advantage for both sm­art­phone manufacturers and users. By eliminating the need for a dedicated SIM card slot, the technology frees up va­luable space within the device hardware. This additional space can be st­rategically utilised by manufacturers to enhance the overall design and functionality of their smartphones.
  • By eradicating the need for physical SIM cards, eSIM technology directly tackles the issue of electronic waste (e-waste) and its associated environmental consequences.

Areas of growth

The emergence of eSIM technology has unleashed a plethora of opportunities for mo­bile network operators (MNOs) and mo­bile virtual network operators (MVNOs) to venture into untapped market segments and strengthen their position. By leveraging the inherent capabilities of this technology, telecom operators can extend their reach into emerging markets, including connected cars, wearables, and smart home devices. These burgeoning markets often demand flexible and scalable connectivity solutions, which eSIM technology is uniquely equipped to provide. MNOs and MVNOs can capitalise on its versatility to craft tailored service packages, pricing models, and value-added services that cater to the specific requirements of the internet of things (IoT) and machine-to-machine (M2M) domains. The growth of IoT and the in­creasing adoption of connected devices are fuelling the expansion of the eSIM market. The technology addresses the connectivity requirements of IoT devices by providing seamless connectivity and remote management capabilities.

This strategic expansion into new market segments not only drives revenue growth but also fosters customer loyalty and market differentiation. The seamless integration of eSIM technology into connected cars is expected to open up a world of possibilities for MNOs and MVNOs to provide in-vehicle connectivity, enabling seamless data exchange, remote diagnostics, and enhanced entertainment experiences. By partnering with automotive ma­nufacturers, telecom operators can establish themselves as key players in the connected car ecosystem, driving innovation and shaping the future of mobility. The burgeoning automotive industry’s focus on connected vehicles is anticipated to further accelerate the demand for eSIMs, po­t­entially reaching 3 million units within the next 12-18 months. Industry experts anticipate that this surge in eSIM demand will also drive substantial revenue growth in the enterprise business segment for te­le­com operators.

The widespread adoption of eSIM technology is being propelled by a convergence of compelling factors. Foremost among these factors is the evolving consumer preference for seamless and hassle-free connectivity experiences. This is driving device manufacturers to integrate eSIM capabilities into their products, offering users the convenience of remote SIM activation and management. Accor­d­ing to Counterpoint Research, eSIM de­vices are experiencing a hyper-growth phase, with shipments expected to reach 3.4 billion units by 2025. The report attri­bu­tes this surge to the aforementioned points. Within the Asia-Pacific region, China is poised to assume a prominent position in the embedded subscriber identity module (eSIM) industry, driven by a massive consumer base and an exponentially expanding market for connected de­vices and services. According to another comprehensive study by Juniper Research, India and China are each projected to have 25 per cent smartphones using eSIM connectivity by the year 2027, followed by the US (10 per cent), Brazil (4 per cent) and Pakistan (3 per cent)

Challenges

The mobile technology landscape is un­dergoing a transformative shift as physical SIM cards give way to eSIMs. While this transition is gaining traction, challenges associated with eSIMs, particularly the tr­a­nsfer process, have emerged as critical areas of concern. These include:

  • Emergency: eSIMs pose a significant vulnerability to communication continuity in the event of device malfunction, ba­ttery depletion, or screen damage. Con­ventional SIM cards, in contrast, offer the flexibility of removal and im­mediate transfer to a backup or secondary device, ensuring uninterrupted connectivity.
  • Unusable in some nations: The exclusive reliance on eSIM technology in certain smartphone models, such as the US-version iPhone 14, poses a limitation on their usability in regions where eSIM support is yet to be adopted by local telecom providers. This limitation can be circumvented by utilising smartphones that support both standard SIM cards and eSIMs, in turn, ensuring se­am­less connectivity regardless of regional eSIM availability.
  • Compatibility: eSIM compatibility is currently available in a select range of pre­mium smartphones in India. These devices often carry a higher price tag, making them less accessible to the average consumer. Additionally, users tran­si­ti­oning to eSIMs may face a more limited selection of compatible devices compared to those supporting traditional SIM cards.
  • Privacy issues: In several countries, including the US, users can self-program eSIMs leading to privacy issues. Further­more, eSIMs empower net­work operators to monitor subscri­ber data, enco­m­p­assing data embedded within applicati­o­ns on the device, especially in the ab­sen­ce of robust data privacy legislation, raising concerns about user privacy.
  • Activation and troubleshooting: Initi­ating eSIM activation often entails a mo­re intricate process compared to activating traditional SIM cards. This stems from the typical involvement of scann­ing a QR code or storing a lengthy activation code. Additionally, resolving eSIM-related issues can be more challenging due to the reduced number of tangible components available for inspection.
  • Costs: eSIMs may be slightly more ex­pensive than traditional SIM cards, as there is more technology involved in their development and production.
  • Technical challenges: eSIMs can be more technically challenging to set up and manage than traditional SIM cards. This is because eSIMs are activated and ma­naged remotely, rather than being inserted into the phone physically. As a result, there is a greater chance of technical issues occurring with eSIMs.

The way forward

While the eSIM market accounts for just 1 per cent of the enterprise revenues of telcos, according to industry estimates, the roll-out of 5G enterprise solutions and the increased uptake of IoT are expected to enhance its share multifold in the coming years.
