Reliance Jio and Airtel have rolled out VoWiFi (Wi-Fi calling) features across India. The service is now available on many devices, but Asus 6z (ZenFone 6) currently not on the official list. Asus 6z has the VoWiFi feature built-in and has enabled in many regions like Taiwan, Brazil, etc., but not in India.

In this guide, we let you know how to enable VoWiFi for Jio SIM in Asus 6z. Asus has not yet enabled the service in Asus 6z units sold in India. The OEMs need to release an OTA update to make it compatible, but there is a workaround for now.

Several users have reported this is working on their device. To work it properly, first, you need to deactivate the VoLTE/Enhanced calling switch, then activate WiFi calling and then activate the VoLTE switch after getting a WiFi calling symbol. Also, you need to repeat the above steps after every restart of the phone.

FYI, VoWiFi (voice over WiFi) service allows you to make crystal clear calls to any network, regardless of network signal strength. Though WiFi calling hardware is available on most of the smartphones, OEMs need to release a software update to make it compatible.
