That's a nice little board! Web search SIM7600X finds various code you can use. Idk if asterisk can support it directly though.
Another possibility might be to use a consumer mobile phone I guess.
I wonder if there might be a 5g version of the board sometime.
I agree, it looks like a nice board!
But... after ordering it I noticed that while the pictures in the website show the "SIM7600G-H" chip - which supports global GSM and LTE bands - the text description specifies that the chip included in the kit is the "SIM7600CE-T", which supports the Chinese bands. I am not sure I will get the correct version now 😅 But there are other "SIM7600G-H" modules and USB dongles available out there, and from what I have found this chip is a nice option for GSM/LTE projects.
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.
