Maybe being the fourth biggest domestic wireless carrier might not be such a bad thing? Sheer total numbers really don't reflect the overall satisfaction a specific provider really radiates. Fortunately for T-Mobile, J.D. Power and Associates recently released the second volume of their 2009 Wireless Retail Sales Satisfaction Study – awarding them the most satisfying wireless carrier. Now the survey was carried out by 8,637 wireless subscribers and conducted between January 2009 and June 2009. Apparently T-Mobile had some high scores from voters when it came to friendly and knowledgeable staff. Not only did they place highest in that category, but they ranked also highest in the category of price & promotions and best retail displays out of all the wireless carriers. It's no surprise that they definitely have one of the best competitive plans to offer to a variety of consumers. It seems like T-Mobile has been on this trend for winning plenty of J.D. Power & Associates awards - maybe they'll repeat again next year?
