Hello, my question is the following.
Is it possible to make a wifi access point with ESP32 and a SIM800 type SIM module?
I want to give internet to other devices like mobiles and computers through esp32.
But this time I don’t want esp32 to get internet from a router but to have internet through a sim card module connected to the esp32 and thanks to it I can give internet connection to other wifi devices.
You can connect the ESP32 to the internet using SIM card as shown in this example: https://randomnerdtutorials.com/esp32-sim800l-publish-data-to-cloud/
As for the other part, I’m not sure.
However, I’ve found this example that might help: https://github.com/SFeli/T-Call_HotSpot
I’m thinking it’s technically feasible but I’m also thinking it would be too slow for multiple WiFi devices. Of course how cost effective would it be and how long will it be available (SIM800 uses old technology that carriers are gradually turning off. SIM8000 is the future for now). An ESP32 is cheap but the SIM800/SIM8000 are pretty expensive. And then you would have to figure out the programming.
If you still have 4GLTE available in your location then you can get a mobile hotspot for less than US$50.
