Is there a SaaS version of this, sort of a Mailinator for phone numbers? Is it possible to hook something like that up with Twilio or another VOIP provider?
You can't use it for certain 2FA situations, but it works for Craigslist transactions or when some business requires it.
Places like Twillio and SIPgate will happily let you rotate numbers - but there is a cost and they're often not tied to a specific SIM.
There was also some concern that apps wouldn't go for it because it made their users look untrustworthy.
