Walkie-Talkie Apps on cell phones still require working Internet access

One exception:

The Serval mesh project is specifically meant to address the situation of
no Internet or cell access. Caveat: it hasn't been updated recently and the
Google app store no longer has it. It is still available via F-Droid. It
looks like it may be useful if one has a working network that is not
connected to the Internet (or has a very poor connection).
