Default [Q] Note 3 data loss

I currently have a sm-900v (verizon phone) and am using metro pcs (t-mobile) as my provider. I am having issues connecting to mobile data. It will connect at random times and sometimes connect for 5 minutes then disconnect other times it will stay connected for a day and disconnect. there is really no pattern to it. It is running android version 4.3, Is there anything to be done to have continual connection?
