How to fix my Wifi calling, Hotspot, and Tethering option on my Galaxy s7 edge.

[David Thurmond]

I had Wifi calling, Hotspot and the Tethering options in my settings menu but now I don't since Ihad it unlocked. With the unlock can I reset the factory settings and will it give me them options back and not cancel the unlock. My carrier has these options in my plan and I can't even use them and I pay for it. I need it fixed!!! I'm an over the road truck driver and I use my hotspot and tethering option to watch my TV. Can someone help me get my toggles back in my settings menu please?!!
