### Description

Monogoto SoftSIM provides cellular connectivity without requiring a physical SIM card, making it an ideal wireless solution for lightweight or space-constrained IoT devices. It is particularly suitable for remote provisioning, large-scale production, and scenarios where simplifying logistics and hardware integration is essential. 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 SoftSIM?

SoftSIM (Software SIM) is a virtual SIM solution that enables cellular connectivity without the need for a physical SIM card or embedded UICC hardware. Instead, SIM credentials (such as IMSI and authentication keys) are securely downloaded and stored within the device's non-volatile memory either during manufacturing or over proprietary interfaces.

### Features

* Manage SoftSIM profiles through Monogoto's cloud-based self-service platform.
* Simplifies device design by eliminating the need for a physical SIM slot or embedded SIM chip.
* Enables remote provisioning of SIM credentials during manufacturing or via secure proprietary interfaces..
* Integrates easily with third-party cloud services through Monogoto's robust API.
* Monogoto secure IoT SIM works on 550+ cellular networks in 180 countries, offering all network technologies. You can check our coverage by [following this link](/getting-started/identity-b-coverage.md).
* Cloud-based private network with hybrid local-breakout. Radio and CPE agnostic solution supports CBRS and any band.

### Technical Specifications

* **Profile Storage**: SIM credentials are stored securely in the device's non-volatile memory (e.g., flash). Some implementations may use secure storage such as TPM or Secure Enclave, depending on the device architecture.
* **Hardware Requirements:** SoftSIM relies on the device's baseband or host processor to emulate SIM functionality. No dedicated SIM slot or UICC chip is required, reducing component count and device complexity.
* **Power Efficiency**: SoftSIM is optimized for power efficiency to minimize energy consumption and extend battery life in battery-powered devices.
