The Invi Messenger uses the device's phone number to register. To confirm your registration, you will receive a message from the developer. If you didn't receive yours, try tapping on “I didn't get the verification code”. To share pictures through the application, you just need to drag them to the chat window to be noticed that the software is in Beta testing. This can lead to several errors. To fix them, try to keep your application up-to-date.
