Ask iphone to have built-in SMS ringtone glass (that is, ding ding twice). This ringtone is built into Apple's mobile phone to receive short messages.

According to your description, the iphone has a built-in SMS ringtone, and there is a tinkling sound, which should be the "button" ringtone as shown in the figure. Like many built-in ringtones, this ringtone is crisp and pleasant. Presumably, Apple has put a lot of effort into this ringtone.

Many friends who use the iphone know that you can often hear the same Apple built-in ringtone on the street, and many people prefer to use the built-in ringtone instead of switching to something else, which shows that users also like the built-in ringtone.
