When AOL switched to "unlimited" usage, freeing users from the need to deal with metered access, usage exploded. For that reason, fixed broadband service plans in the U.S. market have been "unlimited" until quite recently.
That approach generally has not been used in the mobile business, which has more stringent capacity issues. Sprint, for the moment, remains the carrier most associated with "unlimited" access plans. Some Yankee Group research data from the United Kingdom shows the continuing power of the "don't worry about overage charges" approach. About 29 percent of U.K. consumers surveyed indicated they were willing to pay a 10-percent premium to receive protection from unexpected overage charges.
They also were willing to pay more for higher speeds, especially when available "on demand."
