In a survey that asked mobile-phone customers about their satisfaction level with their providers, AT&T ranked at the bottom of the rankings, Consumer Reports announced Tuesday.
Of the four largest U.S. wireless carriers, Sprint and Verizon Wireless were rated the best ahead of T-Mobile USA and AT&T.
Verizon ranked slightly better than Sprint in the areas of texting and knowledgeable support staff, Consumer Reports revealed, although Sprint beat its bigger rival when it comes to value.
"T-Mobile was below Verizon and Sprint but continued to rate significantly better than" AT&T, Consumer Reports said.
The survey of 66,000 ConsumerReports.org subscribers also found that Consumer Cellular, Credo and U.S. Cellular scored better than the four biggest carriers while TracFone ranked as one of the best carriers among prepaid providers.
"Our survey indicates that prepaid customers and those with smaller standard service providers are happier overall with their cell-phone service," said Paul Reynolds, electronics editor for Consumer Reports, in a statement. "However, these carriers aren't for everyone. Some are only regional, and prepaid carriers tend to offer few or no smart phones. A major carrier is still a leading option for many consumers."
The entire report features carrier ratings in 22 metropolitan markets and can be found in the January 2012 issue of Consumer Reports and at www.ConsumerReports.org.
