I was expecting $200-400 but to my astonishment, after pre-orders, it will be $800. So I logically said, "It can't be that hard," and this project was born, make an E-Ink phone for less than $400 with off-the-shelf parts. I decided the first step of this ambitious project would be getting cellular working on a Pi Zero W. I decided to order a Waveshare SIM7600A-H (order at your own risk). My reasoning was that I could just use gpio for the modem so I wouldn't need extra cables. This is where the issues start.
