Hello,

Sorry, this is something SIM provider-specific. Each provider should have their own implementation of the SoftSIM interface and their own process to configure it, something like I pointed out for the Onomondo SIMs.

I recommend checking with your SIM card provider for this.

Kind regards,

Hello,

I'm not sure if there's a generic guide available for this, but I’m checking internally to see if there’s anything I can share with you. In the meantime, I also recommend checking with your SIM provider directly.

By the way, which provider are you using?

Kind regards,
Abhijith

Hi Abhijith,

I have ICCID, IMSI, KI and OPC from my provider. I am looking for any guidance to flash Nordic nrf9151 with this information.

I am not using ONOMONDO SIMs and hence cant use their solution. Please suggest if there is a way to flash SoftSIM without using Onomondo SIMs.

Hello,

Have you checked this with your provider? Onomondo provides a guide for integrating their softSIM with the nRF91 series, but this is specific to Onomondo’s solution. I recommend reaching out to your provider to check if they offer a similar guide or support. You can also refer to this repository for additional information.

Kind regards,
Abhijith
