How to Set Up a Webserver for ESP32 with SIM Module to Display Images on an E-Paper Without Wi-Fi?

Using Arduino Project Guidance

hello, i would like to supply my esp32 with pictures via a webserver which are displayed on an waveshare epaper display. the esp32 has a sim module installed and thus connects to the internet, i don't know how to best implement the webserver as the esp32 should not be connected to the wifi as it is located outdoors, i am not yet sure how and where to best set up the server and how to transmit the pictures.

does anyone have any tips?

maybe simpler to transfer the images using FTP

what SIM module are you using?

Some confusion here. A SIM connects to the cell phone system. Yes that is one way to connect to the internet.
You then say you want a web server but no connection to WiFi
Exactly what do you want, explain in user requirements not soutions.

Sorry, I just meant that the web server shouldn't be local, as all the instructions I've found point to that

to be exact I use this board ESP32-S3 A7670E 4G Development Board, it has the Simcom A7670E integrated

So where do you want the web server to be?

Be aware that the S3 boards have had major changes lately and some stuff is broken. You should probably roill the esp32 boards entry back to 2.0.17 and tuen off auto updates.

i think it is best to host it with a provider

I seem to remember the A7670E supports FTP
how will the ESP32 know when to download a new image?
how often?
