Cellular One, a leading provider of mobile technology and wireless communications to tribal lands and communities in the American Southwest, yesterday selected Optiva to support the modernization of its network and mission-critical launch of VoLTE. Cellular One partners are phasing out their 3G networks to free up spectrum and infrastructure to support new network services. In response to this phase out, Cellular One is transitioning its subscribers to VoLTE service for both in-network and roaming coverage.
