About USA Mobility
USA Mobility was a major US paging carrier formed by the 2004 merger of Arch Wireless and Metrocall, operating the largest one-way and two-way paging networks. It primarily served business, government, healthcare, enterprise, and emergency response sectors with wireless messaging services. The company later rebranded to Spok and shifted focus to mission-critical unified communications software.
