There are two fundamental economic forces at work here. First, metering imposes costs, both on consumers and on carriers. For carriers, there are the obvious expenses of keeping track of billing information, as well as the attendant support costs when an angry customer calls to complain about unexpected charges. For the customer, metering imposes the mental overhead of having to keep track of whether it's currently "peak" or "off peak" time, how many minutes are in his plan, whether he's currently "roaming," etc. A lot of customers are happy to pay a little bit extra for the peace of mind of knowing exactly how much they're going to pay each month without having to keep track of their calling activity. Second, the wireless market, like the phone, Internet, and DVD markets, is capital-intensive. Unless the network is already fully loaded, the marginal user costs wireless carriers close to nothing. As a result, metered pricing often causes under-utilization of the network because minutes are priced far above their marginal cost. Switching to a flat-rate plan can be economically efficient because it encourages greater utilization of the network without undermining the carriers' ability to recover their fixed costs. That has always been the rationale behind the free night and weekend minutes offered by a lot of cell phone companies over the last few years. They're just expanding it so it applies 24/7.
