Anonymous phone line for iphone?

**edit**
It’s my fault for not specifying a few things
1. I’m in the USA
2. I’m not looking for an app, I’m looking for a service that provides an esim or sim card that doesn’t link back to my full name. No contract. I appreciate all the comments with recommendations for apps, it’s just not what I’m looking for and I should’ve been more specific

Reserve your judgment for something else please. I’m here for genuine advice and suggestions …
