"How to send messages in Ukraine if the internet shuts down". "Briar is an Android app that enables so-called peer-to-peer (P2P) communication. Two smartphones connect directly via Bluetooth or Wi-Fi without accessing any existing infrastructure such as network routers or cellphone networks, for example. ... Its big advantage is the direct connection, which is secured by end-to-end encryption. Enemies, secret services, mobile phone providers or hackers won't be able to read your messages. Briar's greatest strength is its ability to bring together a large number of these direct connections to create a network. As a result, communication isn't just limited to two people; a great many people can communicate with each other, over greater distances. This technology is called a mesh network."
