AT&T claims that, Comscore, an independent market research firm has provided a research report, that shows twice as many smart phone users have picked AT&T over any other wireless U.S. carrier, owing to the carrier’s array of smart phones, its fast wireless network, and its 20,000 hot spots.

Today, nearly 32 percent of AT&T subscribers who purchase service on a monthly plan use smart phones and other phones with full QWERTY keyboards, the company said. Overall, AT&T serves 78 million wireless customers.

The research that AT&T presented shows that smart phones and quick messaging phones (phones with text and picture messaging, IM and other mobile data applications) have more than doubled in subscribers in the past year, AT&T said. AT&T noted, without mentioning the iPhone, that it carries smart phones across five different open operating systems, and has nine types of Wi-Fi-capable devices, as well as five touchscreen phones. All the AT&T smart phones are useful globally because they operate on the GSM standard, which is used in nearly 90 percent of the world, the company noted.
