IoT and Wireless eSIM APIs

Embedded SIM (eSIM) is shaping the future of connectivity technology as we know it. With plenty of smartphone manufacturers producing eSIM-capable devices, the world of connectivity API’s for mobile apps is expected to rapidly expand. With unparalleled need for connectivity – both locally and globally – there is no doubt that investing in emerging eSIM technologies is the key to future success. Programmable eSIM APIs are needed to boost the wireless capabilities and supplement the Internet of Things (IoT) especially for consumers. Today’s world is always making advancements in the way people connect, work, study, and communicate. Whether through video calls, VoIP voice calls, text messages, social media, or collaboration apps, there is always a new approach to better communication supported by better wireless connectivity.

A Brief Introduction to eSIMs

eSIM technology has been replacing the traditional SIM card found in phones nowadays. The pressing issue presented by a physical card is that it makes hard for consumers to get or switch connectivity, or even have backup alternative to avoid critical loss connection. The specifications of eSIM  were created by the Global System for Mobile Communications Association (GSMA). Such specifications are mainly divided into Consumer and Machine-to-Machine (M2M) architectural models for eSIM, and both are directly relevant when thinking of wireless eSIM APIs. 

The Consumer Architecture

The primary form of infrastructure was created for mobile phones and the fast-growing industry of smart & connected devices directly used by consumers, from smartwatches to connected drones. Switching things to a user-focused & digital-only model that supports control over the device’s eSIM profiles makes programmable eSIM APIs in higher demand than ever. Now online business can easily add eSIM to their web or mobile offerings and enable new ways of customer engagement and digital product bundling.

The M2M Architecture

This “push” method of eSIM standard was made for industrial use cases that utilize remote servers with more “authority” to manage eSIM profiles. This architecture can operate standardly without much human intervention, simplifying industrial automation and enable more machines to be connected to benefit from new technologies such as 5G and edge cloud computing. 

Why eSIM APIs are essential for consumer apps

Consumer IoT operates around the basis of finding the best accessibility and connectivity options for consumer technology. By enabling software platforms and applications to be linked through programmable eSIM APIs, consumer IoT offers new and better ways of interaction between businesses and consumers. Since many processes are evolving to be highly remote, with increasing reliance on mobile devices, it only makes sense for business to evolve and add new connectivity tech, especially digital-only cellular with its extensive wireless reach. eSIM architecture is allowing companies to source wireless connectivity using APIs. Some of the aspects of this approach include:

1. Re-Programmable Nature

Thanks to the networks available over-the-air through eSIM QR and activation codes, switching profiles and networks on a single device is now much quicker than ever. And with eSIM APIs, connectivity associated with eSIMs can be programmed by many variables including location, time, pack size, and speed.

2. Cost-Reduction

eSIMs eliminate supply chains and the management costs due to their online-based nature. Without the need to have physical distribution channels, companies can save plenty of resources with the digital channels associated with eSIMs. And using eSIM API’s to outsource such cellular data connectivity tech can also make this route very economical and asset-light.

3. Improved Security Measures

Security is improved due to the eSIM being hardwired into the device and protected by strong certificates and new comprehensive Security Accreditation Scheme. This scheme makes it more difficult to locate, remove, and swap an eSIM, which is great for national security measures. 

Final Remarks

eSIM is among the most promising tech features to arrive to the mobile industry this decade. Thanks to better accessibility options and unique programmability, advancements in connectivity have never been more possible. As eSIMs become more popular, so will programmable eSIM APIs for mobile apps, enabling the creation of new digital products & services.
