My Question or Issue

 Hey everyone,

I have a mobile plan with Optus and included with the plan is free music streaming (Data-free) on Spotify. I have been using this quite a bit on my phone but feel a bit limited because I am only on a free plan. I was wondering if I could make a mobile hotspot with my phone and connect my computer with it to stream any song on Spotify. Would this still be data-free or would it use my data because it is on a different device? 

Thanks for all answers!
