I know Ting already lets you set limits per line to cut off voice/text/data at predefined thresholds. I would also like to see the option to throttle data speeds (perhaps go to 2g) at predefined limits. In my case, this is for a childs phone. If they burn through their limit watching videos, I want to stop that before costs skyrocket, but I'd like to still be able to contact them via email and have basic web browsing.
