Why in One Piece, cell phone addicts don't have to eat and drink Lazar, but also have ringtones, which can simulate the images and sounds of callers?

In the comic world, there are many unreasonable places that are also reasonable. For example, the devil's fruit is unreasonable, as well as Sauron's moves, which normal people generally can't do, Frangi's transformation of people, and the principle that water and sea stones will invalidate the devil's fruit (I don't know if there is an official explanation for this). Don't care about the details.
