Default [Q] Chromecast Using phone internet to download wifi to send to ....

So I have wifi at home it sucks the max speed available in our area is 1.5 mbs, but on my phone through lte I get between 8mbs and 40 mbs, so I was wondering if there was any way that I could use my phone internet for accessing say netflix or whatever and using the network at home so that I could connect and send what I'm downloading on my phone to the chromecast. Or are there any other devices that will allow me to do this??
