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.
Sounds like want a pbx with extensions, like astrix. You could program it twilio too
But… sms verification systems won’t honor extensions
