  • This is fucking awesome. I have been seriously considering building something similar, but the high cost and uncertainty of functionality with 4g modems is putting me off. My plan is to use a cm4 with this 2.8 inch carrier board from Waveshare that also has a 480p 2.8 inch touchscreen, since I want something that could actually fit in my pocket.

    To make up for the small screen, I would use something like the fairberry so that I don’t need to use an on-screen keyboard, so the final device would have a similar layout to the Blackberry q10. I was planning on using this SIM7600G modem from Waveshare meant for a pi-zero since I want to be able to actually use LTE, SMS and take phone calls on whatever I build.

    Fortunately, where I live, VoLTE is not required, but I feel like the mandate of VoLTE in other regions means that my modem should also be VoLTE capable.

    You might want to look into postmarketos, since they have support for the Pi and it might make working with Phosh and the modem a bit easier.

    EDIT:

    I would also probably just use a battery bank that’s cheap with around 37wH of capacity for powering the thing. I would extract the battery and BMS from the casing to reduce the size and weight since it would go in a 3d printed case anyways.
