If you are someone who stays in an area where mobile network services get suspended by the government (over non-violent protests and fear of an uprising) or natural calamity hits rather frequently, then Bridgefy is an app you should not miss out on.
It is worth noting that the app requires an active internet connection the first time you install it and setup Bridgefy on your phone. This is a one-time process and you will not need the internet to use the app henceforth. As you can see in the screenshot below, the app has a really simple UI and the setup process was a piece of cake. You could now easily write to your contacts if they have the app installed or broadcast messages to see whether anyone would reply back.
