IoT eSIM Tech

Future-Proof Your IoT with eSIM Technology
  • UICC vs. eUICC: Old Tech vs. New Tech - Flexible SIM management IoT
  • Future proofing IoT Deployments: Over-the-Air profile and network management ensuring IoT devices remain compliant and secure throughout their lifecycle
  • Global Connectivity: Cut roaming charges and stay independent from a single provider
  • Logistics: Single global SKU, easier manufacturing and inventory management. Reduce e-waste and guarantee long term use of the application

IoT eSIM Technology

Common misunderstandings about eSIM and profile management
  • eSIM often refers to the physical embedded SIM chip (for example MFF2 form factor) that is soldered inside a device.
  • eUICC refers to the technology and functionality that enables multiple profiles and remote management.

Both eSIM (MFF) chip and a Plug-In SIM (2FF mini SIM/3FF micro SIM/4FF nano SIM) can be a simple UICC with one static (network operator) profile or an eUICC supporting both multiple (network operator) profiles and remote management. With an eUICC it is possible to receive a (network operator) profile by using a QR code or weblink after the installation, with an UICC the network operator profile is fixed and cannot be changed.

Why eUICC for IoT

Remote management & OTA updates

Update profiles without touching the device.

Global connectivity with one SIM

Avoid roaming charges and ensure local compliance.

Future-proof and flexible

Easily adapt to regulatory or technical changes.

Cost efficient

Eliminate logistics and downtime from physical SIM swaps.

Sustainable

Reduce plastic waste and electronic disposal.

More Secure

Fixed, embedded SIMs reduce the risk of tampering.

The future belongs to eUICC

Companies that continue to rely on UICC risk higher costs, reduced flexibility and limited scalability. With eUICC, you benefit from greater efficiency, security and futureproofing, without the need to worry about physical SIM replacements.

Crout uses eUICC (eSIM) technology and provides SIM cards in all standard plug-in formats, embedded chipSIMs, or as electronic profiles, such as QR codes.
