Working Moms — those who are employed full time and have one or more children in the household — are among the country's highest spenders on cellular phone services, spending 21% more than the average cellular user on their wireless bills monthly, according to new research by Scarborough Research. Marketers of cellular products have a particularly important consumer target in the Working Mom. Not only is this group sizable accounting for nine percent of the U.S. adult population (21.6 million adults) and 11% of all cellular users — but they also are more likely to utilize certain cellular features such as texting and downloading. Further, Working Moms are 14% more likely than other cellular users to plan to switch wireless carriers during the next year, which suggests that providers need to further establish brand loyalty within this group.
