Nice. The 4g module is $17.90 from digikey, much less than last time I looked. I wonder if there's a 5g version. I also wonder if there's any issue using retail sim cards and making LTE voice calls.

Why are people so pissed at this FelixCress guy? He is just wrong, there is no need to debate.

I am really interested in where this project goes.
ESP32 projects are low powered. Not everything needs 5G and the latest Snapdragon.

The actual problem isn't at all making a 4G mini-computer: you can literally buy the necessary parts as modules and wire them together with a a half-way decent microcontroller board and an smallish LED display and then make some code for it in something like Arduino IDE (though I would recommend Platform IO + VS Code instead).
The problem is making it small (especially thin) and capable of running of batteries for days rather than hours.
For example, if you're trying to actually solve the hard part of the problem you would be better of using a micro-controller with an ARM core rather than the ESP32 as those things are designed to use less power. Also you wouldn't be able to use boards as those things usually waste power versus designing your own.
That said, it's a nice hobbyist project.
There must have been a phone marketed as ePhone before now?
If not maybe try Espressone
Are ESP32 secure enough to have them directly on the internets?

Is hackster.io any good for tech news? And is it more of a general tech news site or more specialized?
And if so, any good software/hardware hacking site aside hackaday?
This is ridiculous. What is needed is a support for advert & bloat & forced updates free smart phone, not reinventing the wheel. Yes, someone must be first - but it is about software, not hardware.
