Trying to make a phone proxy (lemmy.world)

I am tired of paying for roaming, of being location tracked by my provider and running out of SIM slots.

So I have decided to connect some SIM capabilities to my server and set it up as a sort of proxy that I could access over the internet to send regular SMS and make regular calls through the server.

As far as I can tell it seems to be really complicated to do in linux and I just couldn't find anyway that would actually support sound over calls.

The only solutions I found right now are to get an old phone (not ideal because of the price, battery and reliability) or use something like

Which can be connected to the server on the aux and serial ports. This is not too pricey but still seems like a bit much for my needs.

My question is, are there better ways? Really all I need is SMS and calls.

I tried looking for that, all I found were pricey enterprise level stuff, small ones that only support 2g (dying protocol), and ones that have a cloud service and not self-hosted. Do you know of anything else?
