Sprint expected to undercut rivals' call plans

By Sinead Carew

NEW YORK (Reuters) - No. 3 U.S. mobile service provider Sprint Nextel Corp is expected to offer flat-rate calling plans at up to a 40 percent discount to its rivals, hurtling the industry into a price war, analysts said on Wednesday.

The two largest U.S. mobile service providers, Verizon Wireless and AT&T Inc, on Tuesday unveiled $99.99-a-month plans for unlimited calls. T-Mobile USA went a step further by including text messaging in that price.

Sprint has yet to respond and spokeswoman Leigh Horner declined comment on any plans for future offers, but analysts say the company could be considering an unlimited calling plan for as low as $60 a month to stem customer defections.

Wall Street is worried about a looming price war, even though Tuesday's new plans were not seen in and of themselves to have a big impact on service revenue as only about 5 to 10 percent of consumers now pay more than $100-a-month for calls.

A response from Sprint may force AT&T and Verizon Wireless, a venture of Verizon Communications and Vodafone Group Plc, to cut their prices or face losing customers.

"Our bigger concern rests with Sprint's plans and the potential for future additional competitive responses," Robert W. Baird analyst Will Power wrote in a research note.

Verizon shares fell 5 percent to $33.52 on the New York Stock Exchange after falling more than 6 percent on Tuesday. AT&T shares fell 7 percent to $33.10, also on the NYSE, after finishing down more than 5 percent on Tuesday.

Sprint fell almost 6 percent to $8.71 after closing down 2.6 percent on Tuesday.
