Embedded SIM and Simless System-on-Chip (S2oC) The future of the SIM is Embedded SIM. And it's all going to be ultimately integrated into the System-on-Chip (SoC). We call it S2oC™.

Are you a manufacturer of a new or already deployed cellular device,
and are thinking about integrating a SIM?
Well, we can help with that.

Embedded SIM (eSIM).

Traditional removable SIM cards are being replaced by remotely reprogrammable eSIM chips which can contain multiple network access applications (i.e. multiple operator profiles).

Thanks to our preferred chip manufacturers, Simless can provide discrete hardware eSIM modules in removable (1FF, 2FF, 3FF, 4FF) and solderable (WLCSP, MFF2) form factors. We can also directly provide non-discrete SoC integrated software eSIM modules. The integrated software eSIM module can be deployed into a SoC as a secure firmware library at factory or over-the-air. The patented "SIM on a SoC" concept is currently being standardized as iSIM, iUICC or iSSP. As the pioneer and leader of the integrated SIM concept, we guarantee you best-in-class eSIM modules at the fraction of the cost of traditional SIM card vendors.

Our secure eSIM modules, rely on a cutting-edge lightweight embedded operating system which currently supports the following industry standards and specifications:

S2oC Components.

Our breakthrough patented S2oC technology consists of essential and unique methods and systems for rapidly combining our digital SIM card platform and the following optimized software packages for making a device eSIM-enabled via just a remote firmware update (i.e. no hardware involved):

  • Local Profile Agents (LPAs) such as the integrated version of our mobile app for consumer UI-based cellular devices (e.g. phones, tablets, smartwatches, etc.) and lightweight proxy native clients for IoT cellular devices.

  • Reference cellular modem logical access interfaces for Qualcomm, Mediatek, u-blox and other modem vendors.

  • Secure Storage and Execution Environment Hardware Abstraction Layers (HALs), whether hardware-backed HALs such as ARM® SecurCore, ARM® TrustZone, GlobalPlatform® Tamper Resistant Element and software-backed HALs such as Emulated TEE using advanced white-box cryptography.

  • Other low-power, optimized core and non-core cellular SoC IP blocks for multi-SIM, multi-active connected devices.

Bootstrap Cellular Connectivity.

This optional feature when activated enables your eSIM-enabled devices to access 2G, 3G and 4G LTE cellular networks out the box without access to Wi-Fi. This feature is critical as it provides transparent transport capability for remote subscription management of the eSIM-enabled devices. Through our strategic partners, we provide global, affordable and reliable bootstrap cellular connectivity in over 200 countries and regions. world image
