I have been using the Zello program for a while now. They have upgraded their software recently and it really becomes a real interesting program.
If you own a smartphone, you can download the program from your app store. It works on a simple 2G connection.
The most interesting channel I have bumped into is the channel "27.555". Just search for the channel without the " " quotes. There are operators from Europe, USA, Hawaii, South Africa, etc, etc.
I have been using it on my smartphone when I was abroad in Thailand. It worked as a jewel on a simple 2G connection. The audio was absolutely clear and I was able to talk with my family.
