In addition to the lawsuit that AT&T already filed against Verizon Wireless over its recent string of 3G coverage advertisements, AT&T is taking its message straight to the public. AT&T said in a letter it published today, "As the U.S. market leader in wireless data service, we typically don't respond to competitors' advertising. However, some recent ads from Verizon are so blatantly false and misleading, that we want to set the record straight about AT&T's wireless data coverage." AT&T then spells out exactly what different types of coverage it provides, and to how many people across the U.S. AT&T also points out that it has a wider selection of smartphones, offers more applications to end users, has a faster 3G network, and points out the ability of its devices to conduct voice and data sessions simultaneously. As part of the letter, AT&T provides links to its coverage maps.
