I didn't see the incoming message or answer the call. A beep will remind you to check it later. What is the name of this function? Which mobile phones have this function?

This is called "notification" or "reminder"

1、iphone 4s

Settings → Notification → In the notification center, there are "Phone", "Information" and "Reminder" in the list.

2. Nokia C6-0 1

Settings → mobile phone → light reminder → light reminder → There are "light flashing time" and "notification event" in the list, and you can view "information" and "incoming call" in the notification event.

Remember, most old Nokia have these functions. Android should be ok, and it will be added later today.
