Signal
Signal lets you send group, text, voice, video, document, and picture messages and calls. Your communication is always end-to-end encrypted to keep your communication safe. We can't read your messages or see your calls, and no one else can either.
Send messages anywhere in the world without SMS or MMS fees. Make crystal-clear voice and video calls to people who live across town, or across the ocean, with no long-distance charges. Signal is recommended by Edward Snowden.
