You know how sometimes in a show or a movie there is a character that has a "radio friend" that they talk to? Yeah that's what I want to do.

But I do not know how to so I came to ask you! Cheap, preferably.

Out of curiosity, I found this app on IzzyOnDroid, (which gave me the idea in the first place) Codec2Talkie that seems to be what I'm looking for but I'm unsure due to my ignorance.

A radio modem seems to be required as the app description dictates. I can find one somewhere no issue. But is this the correct approach? Is there a better way that I don't know of?

You can start listening with a cheap Baofeng walkie talkie and a spectrum analyzer like the TinySA, if you want to transmit you will need an amateur radio license. Or depending on your jurisdiction you can start using open frequencies WO the need of a license.
