SIM Card - Asset relation


i just installed ralph and its the perfect solution for my demands.

The xls import for sim cards works perfect for me. But i have a simple question (maybe I’m just oversee the feature).

  1. Is it possible to “connect” the SIM cards with a Backoffice hardware asset? Because the sim cards should all be assigned to a HW asset which in our case is a smartphone.

  2. Is there a way to get all licenses, hardware assets AND sim cards etc. from an asset holder? I get that you get most of the data from “Settings/Users list/USER XXX/Additional info”. But there i miss the SIM Card relation. Or is there a way to get the data with a report? Is there any documentation creating a Report template?

  1. Not directly, apparently. They have to be assigned to users (or so it seems). You’d have to write something to directly associate cards to devices.
  2. You’d be best off doing api calls for the latter (joining cards with users). You’ll get a list of cards and their associated users. You can take the user id and match with your users. There may be a more efficient way of doing this, but this should work.

The API endpoint for access cards is:


You’ll see

    "count": 1,
    "next": null,
    "previous": null,
    "results": [
            "id": 1,
            "status": "in progress",
            "user": {
                "id": 2,
                "url": "https://yourralph.yourdomain/api/users/2/",
                "username": "youruser",

I talked to the core team today, and it might be something worth adding to Ralph.
We talked about something similar to “Supports” assignment like this: Log in | Ralph 3

Each Support can be assigned to the particular Asset, and be back-referenced from the Asset itself.

What do you think about such a solution?

Hi, yes this soulution would work for my case.

Thank you very much.
