Mobile subscribers were asked about dropped calls, calls that took more than one try to connect, audio problems, issues with voice mail, late arriving texts, web connection problems including slow data speeds, and email connection issues. This survey follows the controversial "balls ad" that Verizon had blanketed the airwaves with in January and February. That ad cited some stats from RootMetrics that T-Mobile and Sprint challenged as not being up to date.
It seems that different surveys will get different responses. Today, a much smaller survey taken of 786 customers of Verizon, T-Mobile, Sprint and AT&T was released by Computerworld. The results showed T-Mobile as the best mobile carrier for 2015. Verizon led when it came to phone call reliability and availability, and T-Mobile led in data speed, customer service, technical support and value. According to those surveyed, Sprint offers the largest lineup of phones.
Two-thirds of those surveyed picked their carrier because of coverage, while 53% picked their mobile carrier because of price.
