SINGTEL will roll out Singapore's first commercial Voice-over-WiFi (VoWiFi) service this August, the telco said on Tuesday.
The rollout follows its Heterogeneous Network trial which had been conducted over the past year at the Jurong Lake District, in collaboration with the Infocomm Development Authority of Singapore.
"The trial found that Singtel mobile users could continue to make voice calls and text over WiFi in areas that are technically challenging for mobile signals as their smartphones transitioned seamlessly between mobile and WiFi networks without the need of an installed app," Singtel said.
"This will allow Singtel mobile users to make uninterrupted voice calls and text over WiFi in locations such as basements and buildings above 20 storeys high."
The new VoWiFI service will be available at any accessible WiFi hotspot, including homes, Singtel Premium WiFi and Wireless@SG locations.
