I figured out how to get in my Hotspot I get 12 GB monthly not much right ?
Does you have a 12GB limit on your total data, or is it just your hotspot? What's your phone and your provider?
I have T-Mobile with an (older, grandfathered) unlimited plan. My hotspot is 7GB, but I only use it for my tablet, which doesn't use much because I don't stream on it.
I use my unlimited plan on my laptop, which is plugged into my phone. Using an app called PdaNET, I can connect my phone to my computer and it uses my unlimited data rather than my hotspot. It does this by using a companion program you install on your computer. It can also be connected through wifi and Blutooth, but I haven't found those to be as reliable.
There are drawbacks.
1. The speed/connection isn't as reliable as "proper" internet. T-Mobile can and does throttle your "unlimited" highspeed during "peak" times if you go beyond 50GB (and I do). Even at full speed, the connection isn't completely reliable, and sometimes I have to reconnect, or even reboot to get the app/program to work properly.
2. It'll destroy your phone's battery. The phone I use is an LG V20. It's a few generations old, but still powerful enough to do everything I need it to do. I also have a V40, which I rarely bother using. The reason I stick with the V20 is that it's the most powerful phone available that still has a swappable battery. Using it for my computer's internet taxes the battery far more than "normal" use, especially if I'm using it constantly for downloading/streaming for hours on end. New batteries are under $10 a pop and it takes at least a few months before they start showing overuse (ie: they start expanding and the life turns to crap). Much cheaper than buying an entire new phone though.
3. It's not particularly good for actual wi-fi. There are programs that can turn your computer's wi-fi modem into a wi-fi router (PdaNET has this built-in), but I haven't found it to be reliable enough to actually bother using. But I live alone in a dinky apartment and am the only one that needs to use my internet.
However, if all you want to do is watch some netflix, all you need to do is use your phone like I've described, and plug your computer in to a TV via HDMI. If you plan to do this a lot, you might want to buy a cheap, older phone that you can swap the battery with after you inevitably fry it, but it's a PITA to constantly swap the SIM card between your phones if you do this regularly.
