Verizon, AT&T Announce Unlimited Plans

Verizon Wireless introduced an unlimited calling plan Tuesday for $99.99 a month, an offer that was quickly matched by AT&T Mobility. Verizon Wireless was apparently the first major carrier to make an "unlimited" plan available nationwide with no domestic roaming or long distance fees. Its announcement was all but five hours old when AT&T announced its own unlimited plan. The stocks of the carriers' parent companies, plus Sprint Nextel Corp., were hit by the price war, even though a relatively small number of heavy cellular users are likely to take advantage of the offers to cut their bills.
