MySudo allows you to create and manage multiple identities each with a phone number and email address, to use for signups, downloads, or anytime you need a private phone number and/or email address.
I haven’t tested this service but here is a critical discussion of Privacy.Com and MySudo. Both services seem to have significant limitations.
Note: MySudo virtual cards are only available on iOS and in the US. The company says Android and more locations are coming soon.
