I would like to use a SIM7600X 4G Expansion Board (like this one) to connect my raspberry pi to the mobile network.

In this raspberry pi I am also running an XMPP server.

I want to then create an account that will bridge SMS messages between the SIM7600 and my XMPP account (should be easy), and ideally it should also be able to bridge phone calls (might be difficult?).

I know about the XMPP-VoIP JMP.chat, and since they are open source I can get some inspiration from them.

I will try to implement something myself, but I am not an amazing programmer. So I am wondering whether there is already some open source project that is more tailored for this application.

    That is interesting, the least you can pay for a sim here is about 2.5 USD/mo as far as I can tell. A phone number by itself is about 1 USD/mo. Vitelity no longer seems to show prices on its public site, but Twilio has NL mobile numbers for 6 USD/mo which seems pretty high to me: https://www.twilio.com/en-us/voice/pricing/nl

    SMS for 2fa is deprecated here because of insecurity and TOTP is generally preferable. Can you use that instead?

    I understand about DIY and am interested to hear how this goes for you. I might like to try it myself.

      Thanks for checking!

      My first choice is a YubiKey, second choice is the Aegis Authenticator app, and the phone I only use for services that force me to. A few still do, unfortunately!

      If I manage to set up something that I think is interesting and functional enough, I will post about it 😄
