VoWiFi or Wi-Fi Calling lets subscribers make and receive phone calls and text messages over their Wi-Fi connection using their smartphones. Calls are made using the dialer.

VoWiFi calls are charged against the subscriber’s plan. For those without an active subscription, local and international voice and text rates will apply.

High-definition call quality will be experienced when both caller and receiving party are on VoWiFi.

Smart also recently activated Voice over LTE (VoLTE) across its LTE sites in Metro Manila. VoLTE is the first, fully IP based carrier grade voice service and uses LTE/4G to transmit voice calls. This is unlike the current setup, where users shift from the 4G network to 2G or 3G mobile networks in order to make a voice call.
