No voicemail notification on watch?

I just got a Hauwei Watch, it's my first Android Wear. So far I love it, not even 24 hours and it's come in handy quite a bit.

I just got my first voicemail notification on my phone and the watch didn't indicate anything. My phone is a Sprint Samsung Galaxy S6. Is this normal or is something wrong? I can't find a single subject on this. Thanks!
