Is there a simple HTTP(S) library that doesn't rely on WiFi? I'm trying to implement a Mobile Network (only) for the ESP32 using Arduino IDE. So to be able to connect to website up/download files etc. I need to be able to handle various HTTP PUT/GET/POST requests. However, the available libraries seem to always rely on additional WiFi related libraries. I don't want to have to load those as well, as they are quire bloated and not needed for my use scenario. 

What options do I have for minimalist HTTP request libraries that does not rely on WiFi or BT or ETH?
The TinyGSM library implements Arduino networking Client base class over GSM modem's AT commands. The library is available in Library Manager.
