A couple of weeks ago, I stumbled across this little device: https://www.waveshare.com/sim7600g-h-4g-dongle.htm. According to its documentation, it is able to write SMS, provide mobile internet, and allow making phone calls (which is quite rare). Does anyone have any experience with this device? And if yes, does it just work with Linux applications like gnome-calls (I know that this issue https://gitlab.gnome.org/GNOME/calls/-/issues/680 exists, but it is basically inactive)?
My goal would be to replace my phone entirely. Currently, I only need my phone for Signal as a primary device as well as for basic smartphone stuff, such as SMS, mobile internet, and calls.
Thanks. I already looked at Flare. Even though primary device support has been implemented (https://gitlab.com/schmiddi-on-mobile/flare/-/issues/128), the last time I used it this feature was disabled by default, because the developer strongly advises user not to use it (https://gitlab.com/schmiddi-on-mobile/flare/-/merge_requests/94).
