Multimedia Messages Won't Download

Hey Guys,

I've been having trouble downloading multimedia messages on my phone. It just sits "downloading" and does nothing. I have one right now that is all of 1kb in size but won't finish. Is this a known thing? I've had trouble with this for what feels like the start of having this phone. It might have something to do with group messaging as well. Any help would be greatly appreciated. I'm using the stock messaging app as well.
