### Description

nuSIM is a software-based iSIM solution from Nordic Semiconductor for the nRF91 Series, replacing the need for a physical SIM card and socket. It reduces device size, simplifies manufacturing, and enhances the robustness of cellular IoT designs.\
We offer flexible pricing, which you can check out by [<mark style="color:blue;">following this link</mark>](https://monogoto.io/iot-pricing-page/).

### What is nuSIM?

nuSIM is an open iSIM standard where SIM data is encrypted and managed within a secure area of the device. It operates as a dedicated software component inside the Arm TrustZone® of the nRF91 processor, enabling fully digital provisioning of SIM profiles during manufacturing.

### Features

* Completely eliminates external SIM hardware, reducing BOM cost and saving PCB space.
* Improved environmental robustness by removing the physical SIM socket.
* Secure digital provisioning process during device manufacturing.
* Lower power consumption compared to traditional SIM solutions.
* Full integration with Nordic nRF9151 and nRF9160 through the nRF Connect SDK.
* Security certification by TÜV Nord.

### Technical Specifications

* Based on the [Redtea Mobile](https://www.redteamobile.com/about-us-overview/#) nuSIM Integration Library within the nRF Connect SDK, with Monogoto profile.
* SIM profile is securely loaded during device manufacturing.
* Credential storage and authentication handled in the secure modem domain.
* Supports LTE-M, NB-IoT, and satellite communication (Satellite/NTN).
* Compatible with Nordic Semiconductor nRF9151 and nRF9160 modules.
