PairVPN Alternatives for iPhone?

I’m currently looking for a way to properly share my mobile data to my Nintendo Switch without actually using my hotspot data that’s limited to 20GB. When I was at college last semester, there was a 3 device limit on their network so my PlayStation Vita I had on hand couldn’t connect to the internet at all without requesting to have a device removed from the network. However, I found a bypass by creating a hotspot from my laptop that shared the WiFi network that it was connected to and it worked flawlessly. I was really hoping this trick would work at home where I don’t have WiFi atm with my iPhone connected to my laptop via PairVPN, however the data usage doesn’t track in the app and instead eats away at my hotspot data.

Is there a method or any alternative app that could help out with this issue?
