The year 2020 just made it more apparent that connectivity is an absolute necessity for everyone. The COVID-19 pandemic has completely reshaped how we work, shop, and socialize, and most importantly, the way we do business. It pushed thousands of businesses to go online and put connectivity as its highest priority to ensure that business operations continue despite the lockdowns. In our effort to switch to more digital means of communicating and working, more businesses start to resort to the use of Embedded SIM technology or eSIM and its associated applications. Its transformative effects stretch far beyond just mobile devices and are set to continue growing exponentially in the next few years.  But how exactly are eSIM apps and cellular data API pushing the boundaries of technology and communication? Read on to find out.

What is Driving the Growth of the eSIM Market?

One of the biggest and most recognized reasons why the eSIM market is growing is because of the growth in the number of consumer devices. With phones, tablets, smartwatches, wearables, and AI-powered digital assistants all relying on eSIM technology, it only makes sense that the technology will only grow as time passes. However, this does not paint the whole picture. Here are some of the other consumer & industrial applications of eSIM that are the main drivers of growth for the technology:

Service providers

The use of eSIMs also allows network operators to support full digital journeys with their customers. This means the ability to sign up new customers without having to go into a branch and being able to sell family bundles where several eSIM-enabled devices in one home can be managed by a single contract.


For automakers, delivering cars to any country without inserting a specific SIM reduces costs and improves customer service reliability.  Rather than outsourcing connectivity to a particular network operator, automakers can handle eSIMs in their vehicles as a managed service. Essentially, eSIM increases the value in connected cars. If you somehow relocate and find it necessary to switch network providers, it’s actually easy to pull it off through the use of eSIM managing over-the-air profile updates.

Shipping and Logistics

Knowing the exact location of goods in real-time during shipment is essential in the shipping and logistics industry. In fact, cellular M2M modules have become very attractive in logistics, especially for use on high-value mobile assets. With eSIM technology and apps, assets can be shipped anywhere, tracked, and provisioned on any network across the globe. The need to swap out SIM cards before and during transit is no longer necessary.


Wearables have been a welcome innovation due to their small size and ability to function almost like a smartphone despite the apparent limitations in size. By eliminating the physical SIM card, eSIM allows designers to create even smaller devices or give them free space for larger batteries and better sensors. Expect to see smarter wearables packed with even more features.


For consumers and industry leaders, the advantages of eSIM and its apps are already clear. The ability to instantaneously access the mobile connectivity service without having to wait for and physically change the SIM from the new carrier is such a small feature but with huge benefits. It basically opened up hundreds of different applications that could help us work remotely and connect better in the new normal.
