I’m looking for a service, that replicates the functionality of email aliases, but with phone numbers.
I’d imagine having one number (99999) which I then could use with suffixes like 99999-1, 99999-2, … etc for services like WhatsApp, telegram, 2FA, etc… if such thing even exists.
I really want a good service for disposable phone numbers. In many countries phone numbers are legally required to be linked to real identities. Its the worse attack on privacy. Still not happy signal requires it and refuses to federate.
It’s also an attack on legitimate services that get inundated with spam/bots/abuse/etc. and one of many reasons why they’re not a widespread thing to begin with.
There are a good number of resources for what you want but I don’t want to name names because they should stay hard to find on purpose IMO.
There’s also many other e2ee chat apps that don’t require a phone number such as SimpleX, Briar, Tox, Session etc.
