Ascend IMS Voice is based on the same technology as VoLTE, but instead of tying the phone number to the carrier network, it moves with your devices. This means the phone number is separate from the network or carrier your device is connected to.
It's never been easier to add voice to an IoT solution. Ascend IMS Voice is compatible with conventional cellular networks (2G, 3G, 4G), low-powered networks (LTE-M), private networks (Private LTE), WiFi, and networks of the future (5G).
Rate plans are available for virtually any phone number prefix and region across the globe in 196 countries.
