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.

    The board finally arrived and it is indeed the SIM7600G-H, which is the global version.

    I tried it on my raspberry pi 5 and struggled a bit because there was a change to the UART interface between the PI 4 and PI 5 and the documentation on this board describes the PI 4. But, after some fiddling around I figured out the correct setting and got it to work. The main difference is that the “UART0” needs to be explicitly turned on because the default debugging UART now uses the UART10 interface that is somewhere else on the board.
