IMC: eSIM, iSIM: Everybody’s Talking Subscriber Identity Modules

As connected devices evolve, the role of SIM technology progresses. Embedded SIMs (eSIMs) and integrated SIMs (iSIMs) enhance IoT deployments with:  

  • Flexibility 
  • Efficiency 
  • Control

eSIM Enables Scalable, Remote Connectivity

eSIM has matured as a global connectivity solution. It supports remote provisioning, eliminating the need for physical SIM swaps. This flexibility supports scalability and simplifies life cycle management.  

With eSIM, global deployments are easier to manage. Service disruptions tied to carrier contracts or regional limitations become less of a concern. 

iSIM Simplifies Design and Reduces Power Use 

iSIM takes the next step by placing the subscriber identity in the device’s core processor. This eliminates the need for additional hardware and reduces power use. The result is a more compact and efficient device.   

iSIM technology also opens space for smaller or more ruggedized form factors. For OEMs and product teams, this approach unlocks design possibilities that were not feasible with traditional SIMs. 

eSIM and iSIM Shift Control across the IoT Ecosystem 

As these technologies mature, their impact goes beyond the device itself. Device makers gain more control over network choices. Operators face new expectations to deliver flexible, scalable solutions. They must respond with services that adapt to dynamic provisioning and integration.
