Anyway, I actually do NOT want a carrier that advertises unlimited data. It's a crock. Nobody can offer their entire customer base unlimited data at a reasonably fast speed for everybody. Any carrier who advertises unlimited data is absolutely throttling that data. It's better for the carrier to be honest upfront.

For example, T-mobile currently advertises plans with "unlimited data" and 500 GB of high-speed data. That basically means you're guaranteed 500 GB of data transmission at a certain speed. (You will use that up FAST with Internet phone calls or video.) Then, T-mobile will definitely throttle any additional data. The throttling is dependent on (1) how much other data is passing through the T-mobile network and (2) how much other data is more important than your "OK to throttle" data.

Throttled data gives me a headache. I'd rather pay a premium for data to be transmitted at a guaranteed minimum speed.
