Dear pros,
I am looking for a solution for my network: I have: raspberry1_connected_hotspot4G_1 (stay in province 1) and raspberry2_connected_hotspot4G_2 (stay in province 2). I want to send data between raspberry1 raspberry2. Do you have any suggestions?
Thanks,
Regards
hng

You can do it here: https://qortex.cc
Difficult if you don't have a public IP address for either raspi1 or raspi2. Have you tried ngrok (https://ngrok.com/) before? You can set up a free account and get a public IP (sort of) to test your raspi1 <--> raspi2 connection.
To test the connection:
- launch a simple tcp echo server in raspi2, say listening to port 14000.
- run ngrok in raspi2 "ngrok tcp 14000" and jot down the returned public IP address
- launch a simple tcp echo client in raspi1 and have it connect to the "returned public IP address, port 14000" socket. Send some data to this socket
- verify the tcp echo server in raspi2 receives the data from raspi1 echo client.
