PTA urges mobile users to enable VoLTE, Wi-Fi Calling for better call quality

The Pakistan Telecommunication Authority (PTA) has asked mobile subscribers to switch on VoLTE and Wi-Fi Calling, according to Profit by Pakistan Today, as a way to sharpen voice quality and cut delays when placing calls over 4G. The move follows consumer complaints about unclear audio and slow call setup, a problem that has surfaced as 4G coverage widens after the recent spectrum auction. The regulator also wants users to check that the 4G/LTE setting on their handsets is turned on.

VoLTE carries voice calls over 4G networks, which the PTA says yields crisper sound and quicker connections. Users need a compatible handset, a suitable SIM and an operator that supports the service. For weak signal inside buildings or basements, the regulator suggests Wi-Fi Calling, sometimes called VoWiFi, which routes calls through a nearby wireless network rather than depending only on cellular signals. Subscribers must enable the option in phone settings and join a Wi-Fi network, provided their device and operator support it.

The authority also told people to confirm their SIMs support 4G and VoLTE, as older cards might need replacing. PTA said these steps could help consumers get a better calling experience as 4G/LTE networks keep growing.
