Ringplus data issues

Anyone else using this company on this phone? I cannot seem to get the data to work properly. I do not know if it's set up wrong or if it's just sprint or ringplus. I've tried every setting and 3g and lte function like dialup when i test the internet. I'm actually ok with that but it would be nice to have regular speeds if i ever needed it away from Wifi. It is hard to complain about free phone service but I'm thinking it's just something simple i screwed up.
