Samsung Galaxy S III (T-Mobile)

I currently have the MyTouch 4G. I use the mobile hotspot on my phone to provide internet for my laptop. I've never had to pay the $20 fee (or however much it is) to use the hotspot...and I have been using it just like this for almsot 2 years now and I use right aroud 5G's of data a month. Can I do this on this phone....or when I go to "turn on the hotspot feature" will it not allow me because I don't have the "paid hotspot" feature on my account?

Can someone test this or that already as knowledge let me know!

Thanks!
