Smart extends VoLTE service to Postpaid Subscribers

Smart Communications announced that its Postpaid Subscribers can now experience high-quality calls with uninterrupted data use with the launch of its Voice over LTE (VoLTE) service nationwide.

What’s VoLTE?

VoLTE enables users to make phone calls via LTE using LTE SIMs and VoLTE-capable handsets, such as the Samsung Galaxy A31 and the Huawei P40 series, for example.

This means that they can simultaneously be in a phone call while actively using mobile data for other applications—unlike in the current setup, where devices shift from the 4G network to 2G or 3G mobile networks during a voice call.

VoLTE, the first, fully IP-based, carrier-grade voice service, will initially be made available to Smart Signature and Smart Infinity subscribers and will be rolled out to more customers in the coming months.

Aside from improved call quality, VoLTE also enables faster call setup, which means the amount of time it takes for a mobile phone to connect to another for a voice call is also drastically reduced.

Using VoLTE-capable handsets, customers can also make VoLTE calls using their phone’s native dialer, and will not require a separate, over-the-top (OTT) application. Compared to OTT apps, VoLTE delivers better voice quality, and also guarantees that the receiver of the call is reached, unlike OTTs that require both caller and receiver to be online and on the same app.

“This service is part of our commitment to bring high quality experiences to our customers by making technologies such as VoLTE available to them,” said Jane J. Basas, Senior Vice President and Head of Consumer Wireless Business at Smart.

Wi-Fi calling

This comes at the heels of Smart’s commercial rollout of its Voice-over-Wifi (VoWiFi) or Wi-Fi calling service, which lets customers make and receive calls and text messages over any Wi-Fi connection using their smartphone’s native dialer, without having to install another app.

Apart from improved calling and messaging experience, Wi-Fi Calling also offers extended network coverage, as customers can make and receive voice calls, as well as video calls, wherever there is any Wi-Fi connection and is particularly useful for use inside buildings, and on higher floors, for example.

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

“With these capabilities, we are enabling more of our customers to enjoy enriching voice call experiences,” said Mario G. Tamayo, PLDT-Smart senior vice president for Network Planning and Engineering. “Through services such as VoLTE, we are also able to maximize our available network resources, particularly for LTE.”

Calls made with VoLTE and VoWiFi will be charged like normal calls against the customer’s active subscription. For customers without an active subscription, local and international voice and text rates will apply.
