What is the best way to measure the reliability of a cellular company? According to the National Advertising Division of the Council of Better Business, having the fewest dropped or blocked calls makes you the most dependable cellular company. That is why the national T.V. watchdog is agreeing with Verizon that Sprint Nextel should not run ads claiming to be "America's most dependable 3G network." Tests run by research company Nielsen-the same company that television networks use to compare viewership numbers during primetime-reveal that the nation's largest cellular operator indeed has the fewest blocked or dropped calls. Sprint responded by saying that reviewers should look at more than one test in case results are skewed by bad weather or a faulty cell tower. For its part, Sprint is appealing to the National Advertising Review Board and stands by its claim. Can't we all just get along?
