I'm not getting my text messages through Verizon Messaging unless application is open. Why?

[Reenwad]

People text me, and when i don't respond they call and ask me why i haven't responded.

I look at my phone and have no notifications of any text messages.

Then I open the application, and they all come flooding in. 

What setting so i need to change, and where?

Which phone model do you have? Do you have a 4G or wifi connection when this happens?

[Ann154]

Do you have background data restrictions on your phone?

[Reenwad]

Motorola Z Force

Yes, 4G and wifi are available.

I dont know if i have background data restrictions.....

[Ann154]

Settings > Data Usage. The background data restriction options are there.

Thank you!  That was it.  I always wondered what that little circle thing was up at the top!  Back to normal now, thank you.
