Best Messengers by Country: Message Anywhere, Even Offline

Internet censorship and shutdowns look different in every country. These guides explain the connectivity situation region by region, what messenger features actually help, and how OSHI compares with other trusted tools like Signal, Briar, Bridgefy and Tor.

Around the world, governments filter platforms, throttle connections, and sometimes switch the internet off entirely. When that happens, the apps most people rely on stop working — often at exactly the moment communication matters most. The pages below focus on practical resilience: how to keep in touch when the network is unreliable, and how to choose tools honestly for your own situation.

Internet Shutdown Survival Guide

What these guides have in common

Every guide is built on the same honest premise: no single app is magic, and the right choice depends on your threat model and who you need to reach. OSHI's strengths are consistent everywhere — offline Bluetooth and Wi-Fi mesh, Signal-protocol-style end-to-end encryption, Tor routing and steganographic covert channels, and no phone number — but so are its limits. Mesh needs nearby peers; a total blackout severs every online path; and a seized, unlocked device is a risk no messenger fully removes. We say so on every page, and we fairly credit the alternatives.

The golden rule: install before you need it

You usually cannot download apps once a shutdown begins. If you are in or travelling to a country covered here, install a mesh-capable messenger (OSHI or Briar) and a reliable encrypted app like Signal well in advance, and make sure the people you need to reach have them too.

How OSHI fits

OSHI is a free, open-source, Swiss-built messenger for iOS and Android (via direct APK). It combines offline mesh for when the internet is gone with online delivery over Tor and covert channels for when recognizable traffic is being blocked. It requires no phone number and collects no readable message content on any server. Read the full feature list, dig into covert channels and mesh networking, or compare OSHI with other messengers.
