Default Using built-in Hotspot with Hotspot Shield

I've successfully using the Hotspot VPN Shield with Wifi-Tether to allow me to circumvent T-Mobile's restrictions, but now cannot get the wifi-tether to work on my HTC One, so I'm using the built-in Hotspot.

The problem with the built-in Hotspot is after starting the VPN Shield, it does not re-route or disguise my traffic, so I'm taking back to the T-Mobile upsell message.

How can I use the built-in hotspot and the hotspot shield like it's used with wifi-tether?
