T-Mobile was asked to turn over more customer info than its larger rivals

T-Mobile received nearly 351,940 government requests for data in 2014, the most out of any of the four national wireless carriers. The nation's fourth-largest carrier by subscriber base disclosed in its transparency report that it had fielded 177,549 criminal and civil subpoenas, 17,316 warrants and more than 3,000 wiretap orders. It marked the first time T-Mobile issued a transparency report, which have become increasingly popular over the past year as civil liberties groups, shareholder and consumer advocates have pressured companies to be more open about when they disclose customer information. T-Mobile was the last of the four national carriers to issue a report.
