Resilient and future-proof global connectivity

An eSIM (embedded SIM) refers to the embedded SIM form (eUICC) or the ability to store multiple profiles and remotely provision them within any cellular-connected IoT device. 
 
eSIM offers a number of benefits over traditional SIM cards, including greater convenience, more storage space, easier carrier switching, and improved security.

Benefits of eSIM

Sim

Long-term reliability

eSIMs offer robust durability, as they are challenging to access and resistant to damage. This attribute proves especially advantageous for global IoT projects, as devices can remain reliably connected for extended periods after deployment. 

Scalable

Compact size

eSIMs are less than half the size of Nano SIMs and do not require a socket, allows them to seamlessly fit into incredibly small devices. This empowers manufacturers to design sleek and streamlined devices that not only conserve space but also enhance battery life for extended usage.

Security

Improved security

By soldering and sealing eSIMs within IoT devices, they become tamper-resistant, safeguarding against unauthorized access. The ability to remotely upgrade sensitive data, applications, and subscriptions empowers connected devices to swiftly adapt and respond to emerging threats, ensuring enhanced security and protection.

Reduced Costs

Reduced Total Cost of Ownership (TCO)

Embedded eSIMs with a single SKU reduce device ownership costs by streamlining manufacturing and supply chain management.

Network swap

Global coverage

Effortlessly switch between 2G, 3G, 4G, and 5G networks worldwide to enhance mobile coverage, while LPWAN technologies like NB-IoT and LTE-M are perfectly suited for long-range connectivity with low data rates.
