Go to Settings > Connections > Data usage, turn mobile data on, click Data Saver, make sure it's turned on, click on "Allow app while data saver on " and make sure messages is turned on
I also took the opportunity to turn a bunch of things off.
Hope this helps...it fixed it for me.

Same problem here. I thought it was me but I see now that it is not. The only thing it will send MMS messages on is the app it came with. I thought this was supposed to be a great phone. Well if I cannot use the messaging app I want to it is not great.
