I am writing a small program to help.
I need to send data from one device to another (phones), but they are on different wifi networks. Conditionally, in different cities.
Can I just save some string  with the data to the server or even google disk, so that then the second device will loadStrings () from there?
Or use another method?
If you can do this with the .net library, then how does it work?
I tried to figure it out, it didn’t work out.
Can a couple of lines of client and server to understand?
Which team receives the data, which gives?
How to understand what your ip is or how it works at all?
I hope for help.
Peace for everyone.
