Signal

Using Signal, you can communicate instantly with your relatives without making a compromise on privacy or security. Make video calls, send messages, pictures, videos, documents, voice recordings, GIFs, contacts & location, create groups so that you can chat in real time with all your friends at once and react to their messages with emojis -all with complete privacy-. Signal servers never have access to any of your communications and never store any of your data.

Say Anything – Share text, voice messages, photos, videos, GIFs and files for free. Signal uses your phone’s data connection so you can avoid SMS (No longer supports SMS or MMS) and MMS fees.
Speak Freely – Make crystal-clear voice and video calls to people who live across town, or across the ocean, with no long-distance charges.
Make Privacy Stick – Add a new layer of expression to your conversations with encrypted stickers. You can also create and share your own sticker packs.
Get Together with Groups – Group chats make it easy to stay connected to your family, friends, and coworkers.
No ads. No trackers. No kidding. – There are no ads, no affiliate marketers, and no creepy tracking in Signal. So focus on sharing the moments that matter with the people who matter to you.
Remain Connected – Push notifications let you know when new messages have arrived, and they’ll be waiting for you even if your battery dies or you temporarily lose service.
