Hey kiddo! Have you ever heard of voicemail? It's like a message someone can leave for you on your phone when you can't answer it.
Well, ringless voicemail works a little differently. Instead of your phone ringing, it goes straight to your voicemail and leaves a message without ringing your phone.
It's like a sneaky message that goes straight to your voicemail box without bothering you while you're doing something else. Pretty cool, huh?
