Pi3 + screen + 20ah lipo + mic + speaker + usb 4g modem (removable) and linfone or equivelent. Just need a 3d printer so i can print the case. A bit of a brick. but a quite the "swiss army knife" of comms. I also dont know how many people are aware just how sensitive the mic is on modern phones. I wrote a little app that turns android phones into bugs (broadcasts sound from the mic over wifi) a few years ago. It can pick up a whisper from 40m away, while when using it as a phone there is never any background noise.

  Thats not a modem, it suffers the same problem (mic connected to the - compromised - baseband processor). To hook a mic to the Pi you need an ADC to the GPIO or something like: https://www.element14.com/community/community/raspberry-pi/raspberry-pi-accessories/cirrus_logic_audio_card?ICID=wolfson-cirruslogic-section https://www.element14.com/community/community/raspberry-pi/r...
