You can walk into a prepaid wireless store and grab a new Android phone for $20.
These phones really are so bad. Give it a go. Usually it's a horrible mess of Chinese tracking code, shitware apps you can't uninstall, and it won't be getting any system updates in a year.
Buy an older flagship second hand phone for $20, that's going to be much better experience than a new $20 one, even if it's 5+ years old and doesn't look good anymore.
