What is the Job of second lens in dual camera Mobile phones

Somewhere I read that two lenses are required to create a DSLR effect- Blurring the background. But today I read, the Aperture size is responsible for blurring the background,

So any lens (single camera) with a large aperture will blur the background, so No need to add another one.

In my iPhone X, there are two lenses- wide angle and telephoto lens, so does that mean wide is used for closer objects and telephoto is used for distant objects. ??


Two lenses are required to create a sort of 3d effects in portrait pictures?
