Yeah, I'm a little confused on the use case for this. I guess I could put all of the annoying services that demand a phone number for totally-only-security purposes-trust-us into a "bucket" number. It doesn't sound like it is a feature but I'd prefer that calls and texts to that number just be outright ignored unless I've turned the number on temporarily for verification. But since they have started rejecting VOIP numbers for verification, and now even prepaid phone numbers (!) for verification I feel like this probably won't work for that either.

I personally only use prepaid cards so a service that makes them appear like post paid might be useful on its own though.

The fact that you only get one number and you can't change is seems to blunt some of the utility. Ideally you'd want a separate number for each service and to have them all turned off, to block identifying you as the same user of different services. Not quite as easy to do with finite numbers as with email address suffixes.

I wonder if you could use this like 5sim or other shady text verification services by just remaking a monthly account. I suspect that is not the idea here and probably forbidden, otherwise they'd let you change numbers.
