A J.D. Power and Associates report released Wednesday found that T-Mobile was the highest ranked wireless carrier in the Western states, performing particularly well in billing, service plan options, customer service and cost of service.

T-Mobile was a top performer in five of six regions nationwide including four ties, tying in some areas with Verizon Wireless, which was top ranked in four regions with three ties.

Nationwide, the number of households with multiple members sharing wireless service plan minutes rose from 21 percent in 2003 to nearly 50 percent in this year’s survey. Customers that share minutes within their household reported higher levels of satisfaction overall and said they were less likely to switch carriers in the next year.
