There has been much said about the new AT&T data plans, with particular emphasis on the iPhone, as it requires a data plan. Here are some numbers:
$15 / 200 MB = $0.075/MB $25 / 2,000 MB = $0.0125/MB
Then there are the overage charges. This is silly. If they aren’t going to offer an unlimited plan any more then just move to a standard flat rate per MB charge. Here’s what I’d suggest:
$5 charge per month to enable a data plan $0.025 per MB in usage fees
On the low end, for people on the 200MB per month plan it brings the price down even further, to $10. On the high end, 2,000MB per month, it jumps up to $55. Use more, pay more, while making it fairly cheap to use it reasonably.
And all that should include the tethering feature, no extra charge. So what if people use more data when they are tethered, at $0.025 per MB they’ll be making plenty off of it.
