With these plans we a forced to use up priority data for surfing etc where speed is not all that necessary. I would like to be able to specify whether or I want to use priority data or not for my current session. And of course if we are out of priority data it doesn't apply.
I've always felt the same way. I am on a Liberty 12 plan, which works pretty dang good for me, but I would be happy if I could lower my speed to 1 mbps if it meant preserving my priority data to use during prime time or when I have company.
