I like the Unlisted app https://www.unlistedapp.com I got it a few years ago and haven't had any problems. I think it might be iOS only. There are plenty of other burner phone number apps which work on both Android and iOS.
Thanks for using and recommending Unlisted! We added an Android version last year and both apps are under active development. I'm happy to answer any questions (or receive feedback about what we could do better) - [email protected]
