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 need it to be my number and to not be flagged as a bot, so commercial voip is a no go

???

There are a lot of reputable VoIP companies, my employer right now uses them and we never faced a problem. But makes sure it is reputable ;)

And you could also port your number so to all effects it is your number.

I don't know, I still believe it is the easiest way forward. But in the end it is your call

I have heard of situations where companies refuse voip numbers for authentication or critical services, and i can't risk my number getting flagged as it is sadly a critical part of your online identity these days (fucking hate that)

For example, it's impossible to link Zelle to a VoIP number, you can only use email
