HTTP INJECTOR
This app can get you unlimited internet in a few ways. Some methods are confusing and complicated. Most of the time I just use 'Hotshare' (under tethering tools) to proxify my Hotspot... but this app is capable of way more.
PDANet
This is an app actually worth paying for. PDANet can give u tethered internet (USB) to your computer, it can Bluetooth share it, Wi-Fi Direct to your computer or android device, it can also just do the regular old wifi Hotspot (if your phone doesn't do it normally, or isn't part of your cellular plan). It has the option to hide your usage from your carrier. To Tether it to your computer you just have to download a small program (also in the link below).
I like to USB Tether my phone to my computer with it, then use an ethernet cable to connect my computer to my router, casting my Hotspot out from there (to my PS5 or whatever). **I'll explain how I manage to do that elsewhere on this page.
If you don't want to pay for it, download the Modded version here:

If you don't mind paying for it, use the Play Store link below.
Psiphon Pro
Psiphon Pro is a VPN, which is good for hiding what you're doing. It has several uses, it can even be used to get free internet. Psiphon can bypass internet log-on pages too (like at motels or restaurants).
Once I got free home internet for over a year with this program, after my AT&T U-Verse internet got shut off. A screen would pop up on my computer saying my internet was disconnected until I payed it (modem still hooked up of coarse), all I had to do was run this program and minimize the AT&T pop-up, and I had free internet, until the company came to my house and disconnected me from the power lines.
Connectify Hotspot
Connectify Hotspot allows you to share any available connection over Wi-Fi or EtherNet. I sometimes use it to route my phones Hotspot thru my computer and out to my router.
Here's 3 different full/cracked versions of Connectify Hotspot (one might work better than the other, depending on your operating system):
