Just three months ago, SingTel announced their intention to deliver voice over LTE (VoLTE) services in Singapore. Starting on 31 May, SingTel is launching 4G ClearVoice nationwide, a commercial full-featured voice over LTE service that offers a complete suite of telephony features such as call waiting and forwarding on the LTE network. To ensure a high-quality customer experience users are automatically switched to the 3G network if out of LTE network coverage.

4G ClearVoice complements SingTel’s efforts in delivering the fastest mobile broadband services in Singapore. Customers will enjoy the flexibility of making HD voice calls and using ultra high speed LTE mobile data services at the same time.

The service offering leverages Ericsson’s comprehensive voice over LTE solution which includes the voice handover technology Single Radio Voice Call Continuity (SRVCC).
