I don't receive text messages unless message app is open, why is this happening?

[AC Question]

I don't receive text messages unless message app is open.

this problem started about 2 weeks ago. I don't receive text messages nor the notification for the message until I open the message app on my s6. My husband receives a system failure message when he texts me from his s6.

That says it's a carrier problem - the system that's failing is theirs. Contact them.
