Private Text Messaging + Calling is an anonymous SMS app for Android. You can send text messages with your phone number and it will be hidden from the sender.

Your regular conversations and messages can be intercepted without your knowledge because they are transmitted across unsecured phone networks. Calls and texts on CoverMe Private Messenger are highly protected and entirely anonymous thanks to encrypted data transmission technology. This is an end-to-end encryption that protects everything from hackers and snooping eyes. E2E encryption only functions between users of the same app.
