hello,
I use ESP32-S3 with e-sim and as operator I use "truephone".
I'm using the TinyGsm library to connect with GSM but I'm having connection problems:
to the call http.get(host, path); it says "Connection Failed" Error -1
The same code with wifi and ethernet works perfectly.
I have somewhere that it is better to use ArduinoHttpClient library and NOT HttpClient, of course I use the second one 
But is it really so? Would it be enough to change the library?
Thank you

Add is the eSIM properly provisioned on that network?
Are you sure that you have "truephone" service at your location?
Probably suggests that the problem is with the cellular connection.
Have you done basic connectivity tests:
Can you "see" the network?
Can you register to the network?
Can you register to the APN?
Can you establish a data session?
The link works because I have an SSL connection for MQTT.
I receive an apputno message from MQTT that closes this communication and opens an HTTP one to download Json files.
Does that include shutting down the cellular link?
I close the MQTT connection with mqtt.disconnect();
And does that include shutting down the cellular link?
Excuse me for late answer.
I only close the MQTT connection not the GSM one.
To understand, if I ask for the IP, it returns it to me. So it's connected.
