Recently Apple Inc. has launched their next generation mobiles i.e. iPhone 14 series with an embedded eSim rather than a physical SIM. Though eSim was launched by Apple in 2022, it is not new to the IT world. As it was first introduced in early 2016 by Samsung in their IoT devices.

Nowadays most IoT devices are embedded with different sensors to collect, exchange and share data with other devices. But the main concern of these sensors is the misuse of private and sensitive data. This concern can be overcome by using eSim embedded with IoT devices. eSim provides security and integrity for data transfer. With security, eSim can also provide some other benefits. Let’s take a look one by one:

• No physical handling of SIMs
  As eSIM is an integrated chip, there is no need for separate handling and managing of the physical SIM. It eliminates the need to purchase new SIM cards and physically replace legacy SIMs. Also, it will reduce space in IoT devices.
• Unique sim for different cellular network
  when changing to a different carrier network or different cellular network (2G, 3G, LTE, etc) eSim eliminates the need for physical SIM change. eSim is available in all forms and meets the unique needs of each device. This helps IoT designers to reduce efforts working around a particular SIM size and shape, or specific carrier network requirements.
• Reduce the complexity of stocking, procuring, and managing SIM Cards
  Most organizations traditionally relied on stocking, procuring, and managing various SIM cards. eSim will reduce the complexity and cost of these factors for each of the regions in which they operate.
• Minimize logistic costs and maximize investment in IoT devices
  Organizations can minimize the logistic cost as there are no physical SIM cards available and invest more in IoT devices which will help to improve their efficiency.
• Effective supply chain management
  With no need to physically replace legacy SIMs, organizations can eliminate the process of managing costly and time-consuming truck rolls to dispersed geographic locations and manage supply chains effectively.
• Easy upgradation
  Another main advantage of using eSIM is its future-proof design, reliability for the entire lifecycle of the device, and its easy upgradation. No new SIM card is required When legacy systems are retired, the transition is smooth.
• Remote maintenance
  Instead of frequently sending out technicians to update each device and SIM card at the expiration of MNO contracts, eSIM technology provides service suppliers the power to update their devices remotely. Employing a web portal, technicians will update a device’s network supplier from the comfort of their workspace, saving prices and time from unnecessary maintenance visits.

eSIM can be a powerful tool for simplifying management and security in IoT devices. By using eSIM, you can manage your devices more securely and efficiently, and you can also keep track of your device’s data usage. If you’re looking for a way to simplify your IoT experience, eSIM is definitely worth considering.
