I'm trying to set up a ghost account on Amazon but can't seem to be able to add a phone number

Have you tried these services?

https://www.privateline.app
https://hushed.com
https://www.burnerapp.com

Tried Burnerapp and didn't work but for the other 2 I'll keep them on the side and test them.

For the solution I found, it's not quite a solution to my problem but instead found a amazon acc seller who sell some aged account with order history.
Will try these instead.
