In order to enable a more streamlined Signal experience, we are starting to phase out SMS support from the Android app. For those of you interested, we walk through our reasoning in more detail below. We have now reached the point where SMS support no longer makes sense. But this came with a tradeoff: it meant that some messages sent and received via the Signal interface on Android were not protected by Signal's strong privacy guarantees. We did this because we knew that Signal would be easier for people to use if it could serve as a homebase for most of the messages they were sending or receiving, without having to convince the people they wanted to talk to to switch to Signal first. And we continued supporting the sending and receiving of plaintext SMS messages via the Signal interface on Android. In this time we changed our name, built iOS and desktop apps, and grew from a small project to the most widely used private messaging service on the planet. Almost a decade has passed since then, and a lot has changed. Our Android app was called TextSecure and the Signal encryption protocol was called Axolotl. To give some context, when we started supporting SMS, Signal didn't exist yet. You'll have several months to export your messages and either find a new app for SMS or tell your friends to download Signal. Schwit1 shares a blog post from Signal, the popular instant messaging app: In the interest of privacy, security, and clarity we're beginning to phase out SMS support from the Android app.
