Motorola ( MOT) seems to have escaped a major case of Razr burn.Last week, big wireless service providers Cingular and T-Mobile halted sales of the world's most popular cell phone after customers discovered a malfunction that caused calls to be lost. Shares of the Schaumburg, Ill., wireless tech titan slipped Friday as word of the hangup hitch got out. But on Tuesday, Motorola said it has the problem in hand and that it doesn't expect to see any financial impact. Some Wall Street types concurred, saying sales shouldn't be hit too hard. On Tuesday, Motorola rose 41 cents to $21.31. Cingular, a joint venture of prospective merger partners AT&T ( T) and BellSouth ( BLS), and Motorola have said that the Razr problem is limited and being corrected with new phones. Some analysts who have checked with stores say the situation may take two weeks to resolve. "We believe a 10-14 day pause in sales is not unreasonable to assume given the time it takes to identify the problem, remove the defective product, and restock with new product across thousands of retail locations," writes JP Morgan Chase analyst Ehud Gelblum in a note Tuesday. "This would put Razrs back on the carriers' shelves and selling in volume between Monday, March 20 and Friday, March 24," says Gelblum. For its part, Motorola emphasizes its quick action in recognizing the unpopular dropped-call feature. "As the world's most popular mobile handset, the Motorola Razr is recognized everywhere for design and quality," the company's flack says in a statement. "So, when Motorola becomes aware of an issue affecting quality, we take immediate action. "Every minute of every day, Motorola continues to deliver a robust supply of quality-approved Razr handsets to the world's retail channels," the flack adds. "Additionally, Motorola does not expect any impact on financial results." That said, Gelblum estimates that some 500,000 phones won't get sold as a result of the glitch. He points out that Motorola sells about 43,000 Razrs a day to Cingular and T-Mobile, a unit of Deutsche Telekom ( DT). At $200 a pop, that makes for a $100 million hit to the quarter's sales. That may sound like a lot. But for the first quarter ending March 30, Motorola is expected to post $9.5 billion in sales. So if the Razr hitch is limited to two weeks, then a 1% divot on the top line might not get much attention. "In my experience," says one Wall Street analyst, "these things don't always warrant a red flag -- but maybe a few yellow flags."
