Latest tests show all four major wireless carriers are strong

Despite claims by the four biggest U.S. wireless carriers that each one has the best nationwide network, the latest performance data gathered by testing firm RootMetrics shows that are all good and getting better."This a great time for consumers. Network providers are really trying hard so that consumers ultimately benefit. You're not going to go wrong with any one of them," said Julie Dey, vice president of RootMetrics, in an interview.The competition between all four has been tight for years, but came into special focus in the last two months as Verizon, then T-Mobile and Sprint started running separate national ads that show tiny colorful balls running down a track with a narrator asserting each carrier's network superiority.To read this article in full or to leave a comment, please click here
