I want to be able to not always use data on my iphone 7 and i know i can use personal/mobile hotspot. how does that work? can you use that instead of using data if you want? please explain, thanks. 😀
I believe you misunderstand what the mobile or personal hotspot is on the phone. That allows you to use your cellular data to set the phone up as a hotspot and allow you to connect other devices to use your cellular data. If you are not wishing to use your data on the phone for yourself, setting up a hotspot would only compound your problem.
You can take a look at this support document and see if that explains things for you better. Share your Internet connection with Personal Hotspot - Apple Support
