The Onomondo SoftSIM is a software-based SIM solution that enables cellular connectivity through Onomondo's global network while eliminating the need for a physical SIM card.

In order to get the Onomondo SoftSIM to work on the Quectel BG95 Series radio modules, it is first required to install a specific Quectel radio module firmware that allows for SoftSIM functionality to be supported by the lower level software, and then afterwards installing the Quectel BG95 x Onomondo SoftSIM application on top.

Before you can flash SoftSIM onto your device, you'll need to provision it using the Onomondo SoftSIM CLI tool. This tool aids in setting up your SoftSIM-enabled device both before and during production.

The SoftSIM CLI tool is a tool developed to simplify the provisioning process. Using the CLI tool, you’ll be able to quickly fetch active SoftSIM profiles. Additionally, the SoftSIM CLI tool will help decrypt and encode the profile, so it can be parsed by an embedded device.

You can access and download the CLI tool from our GitHub repository here. Detailed information is available in the "ReadMe" file within the repository or in our CLI tool Knowledge Base article.

With your SoftSIM profiles ready, the next step is to flash them onto your device. This process varies depending on the type of module you will be using with SoftSIM.

The following are specific to the BG95-M3 module.

This Quectel BG95-M3 / BG95-M5 SoftSIM beta release has been developed using the QuecOpen SDK.

In order to enable SoftSIM, the actual SoftSIM application needs to be copied to the device.

To set up SoftSIM on Quectel’s BG95-M3 / BG95-M5 module, please follow these steps:

1. Enable support for software-based SIMs:

Flash the firmware provided by Quectel using QFirehose or an equivalent software.

On Linux:

2. Instruct the device to look for a SoftSIM application on boot:

Copy oem_app_path.ini to /datatx on the device. Use the supplied tools for this.

On Linux:

3. Copy the SoftSIM application that is loaded as a module on boot:

Copy quectel_demo_softsim.bin to /datatx.

4. Read & activate the profile:

Copy a profile to the same directory (/datatx) on the device, and the file must be called profile.

On Linux:

This profile is read when the device boots. After successfully writing to an internal flash section, it will be deleted from the file system.

Please note that the device should be re-initialized to make the new profile active. This is typically done by setting the functionality level to 0 (AT+CFUN=0).

Example of the profile content:

The actual profile is available through our Onomondo SoftSIM CLI tool.

Now that you've finalized flashing the SoftSIM onto your device, it's time to test it.

With the Onomondo platform, you have the advantage of diving deep into the SIM's connection details using features like Network Logs, Traffic Monitor, and Signaling Logs.

Please note that, by default, your SoftSIM is active in your Onomondo account and attached to a global network list.

Congratulations on successfully provisioning, flashing, and testing the Onomondo SoftSIM with your device!
