I’m able to send and receive some locally from my brother in Missouri, but I’m not getting any through from my friend in NY state. Also, my phone has started to randomly vibrate or chime as though I’m getting a new text, but when I look there’s no new messages. Any ideas on how to fix this problem?

Are you using Hangouts?
Just noting that the Samsung Messaging default app in not compatible with Republic 3.0 and Google messenger is recommend though there are a few other 3rd party apps that will support the System API in there setting that can be used also (Chomp, Textra,)
