Tethering counts towards allotment. Free streaming is to phone only.
Just stopping in to say snn555 is right about tethering. You can take a look at our Music Freedom page under the other info to be aware of under the Things to keep in mind section of that link.
Just me speaking from my own experiences.... I have a 6GB Mobile Internet Hotspot and after I use the 6GB of High Speed 4G Data i get throttled down to 2G speeds until the next billing cycle. I tested this out several times, while tethering at 2G speeds I am still able to listen to my music (Music Freedom). I mainly use the TuneIn app, and i have no worries when I get throttled because I only use that line for music .
I am very confused about this post... if ever you use your 10GB in the future... try tethering at the throttled speed and see if my words are true .
