I would recommend KLink WIRED tether, it hides your data usage most of the time coupled with a DNS Changer. You should get Hotspot Shield VPN and when you use the VPN you can do stuff you can't normally do on a vanilla tether or even the 'Fi
Hotspot shield was $8.99 a month but you can cancel your subscription if you can't pay right away. I have in-home Wi-Fi now so I no longer need it.
..and yes, Hotspot Shield does work through a wired connection, just in case this raises any questions.
