What does the Japanese short message ringtone "Oh, as big as a mill and as big as Moses" mean?

Why doesn't it have anything to do with the phone? Moses = Hello, isn't it the most common way to answer the phone? There is only one hello in Chinese and two in Japanese. Others should have an audio address to help you hear what it is and the distortion of the report.

It means ぉなのだもしもしなのだ.
