The content of the SMS prompt is different.

This effect can be achieved by the combination of carriage return and space character, but it is obviously much more complicated. The font size sent out is still the original size. For example, the font size of "I am a genius" SMS is actually determined by the other party's mobile phone. For example, if your mobile phone font is small and displayed with a large gap, it depends on the mobile phone. For example, many domestic mobile phones have large fonts.
