AC Question

I want to use my Galaxy S6 with the Screen mirroring on my tv (using Amazon Prime movies mostly) and I don't want to use my WiFi connection in house.. using my Data on phone is unlimited so I want to use that... I was told I needed a Samsaung smart tv but will I STILL need to use my house WiFi to make the mirroring work?
