Comment Charge for tethering is a complete rip-off now (Score 5, Insightful) 514
The ridiculous part is that they're still charging a fee to enable tethering. That sort of makes sense with an "unlimited" plan. Presumably, the plan price was based on an estimate of how much data you'd use. Since tethering will obviously drive up usage, that assumption is no longer valid. (This highlights the absurdity of so-called "unlimited" plans that aren't really.)
But now that you are paying for actual use, there's no excuse to charge anything for tethering. You've paid for 2 GB (or whatever), and it shouldn't matter how it gets used. If you use more, you pay more.
I'd really like to see a regulatory authority question that charge.
