There seems to be people in these comments that know, so: is there something similar to the ESP32 but for cellular networks? A small, cheap microcontroller that I can add a SIM to and get connectivity?
The only ones I've messed with before were from Adafruit, but they are all 3g which is, afaik, completely decom'd now.
