SingTel, in collaboration with Ericsson and Samsung, is readying the launch of Voice over LTE (VoLTE) services in Singapore in the coming months.
Powered by Ericsson's VoLTE solution, SingTel said the service will allow customers to enjoy conversations that are significantly clearer than conventional mobile voice services.
In addition, calls will be connected in less than two seconds compared with five to 10 seconds on 3G networks.
Customers will have the flexibility to make calls and use 4G mobile data services at the same time without compromising 4G data connectivity speeds.
SingTel's VoLTE service will be the first of its kind to be equipped with Single Radio Voice Call Continuity (SRVCC) capability. This automatically switches ongoing calls without interruption to the 3G network if users lose connection to the 4G network.
SingTel will work with Samsung to introduce a range of VoLTE-compatible smartphones to Singapore, such as the next Galaxy S device. The Samsung Galaxy S4 and Galaxy Note 3 will also receive a firmware upgrade in the coming months to support the service.
