Using Signal, you can communicate instantly with complete privacy. Signal uses your existing phone number so there are no separate logins or usernames to manage or lose.
Signal Android users can
- privately message, voice, and video call other Signal users all over the world for free over the internet. Signal will use whichever internet your phone is connected to -- your WiFi or mobile data connection.
- send insecure SMS/MMS from your mobile SIM card number which incurs costs and limits as set by your mobile plan. Invite your contact to Signal so you can chat privately and for free.
