You can change your number
Why would supposedly secure communicator use actual phone number as identifier is beyond me.<p>And everybody does that, either phone number or email.<p>The only software I could find for anonymous communication was old Polish communicator <a href="http://gg.pl" rel="nofollow">http://gg.pl</a> which uses arbitrary numbers as identifiers<p>I understand that startups are scared that they won't be able to build up userbase from scratch but come on! Discord and Slack did it.
