FRAMINGHAM -- Cingular Wireless is running ads saying it has 'the fewest dropped calls,' and Verizon Wireless is running ads calling itself 'the nation's most reliable wireless network,' but Mort Rosenthal says no one company has the best coverage everywhere.
Rosenthal, the chief executive of IMO, a new breed of retailer that sells every major wireless brand, knows what he's talking about. The Waltham company has done its own road testing and, unlike the cellular companies, makes the test data available to customers so they can tell town by town, or block by block, which carrier has the strongest signal coverage.
