Viva Bahrain has launched voice-over-LTE (VoLTE) across Bahrain, offering customers with selected Samsung devices the voice service over 4G. Viva’s new service will be made available to all customers with VoLTE-enabled Samsung devices.
With VoLTE, Viva customers will be able to make and receive better-sounding HD voice calls while still instant messaging, video streaming and browsing the internet over 4G. Connection speeds will dramatically increase as call setup times drop from approximately eight to only two seconds, the operator said.
