Encrypted Messaging Between iOS and Android Devices For Free

Posted March 4, 2015

Open Whisper Systems announced the launch of Signal 2.0, with support for TextSecure private messaging. The free app allows users to send end-to-end encrypted group, text, picture, and video messages between Signal on iPhone and both RedPhone and TextSecure on Android, all without SMS and MMS fees.


Signal uses your existing phone number and address book. There are no separate logins, usernames, passwords, or PINs to manage or lose. Messages and incoming calls are fully asynchronous; push notifications let you know when new messages have arrived. It uses end-to-end encryption protocols and store messages locally in an encrypted container. Messages sent over the WhisperSync server are encrypted.


The software has been released for free to the open-source community via Github, which paves the way for improvement and verification by other security professionals. The free software gives users the option of encrypting calls and text messages without having to pay monthly subscription fees. Now you can make private phone calls to people who live across town, or across the ocean, with no long-distance charges.
