Asus ROG Phone 2 VoWiFi (WiFi calling) support enabled for Reliance Jio after recent update

Asus’ ROG line of devices has hardly been around for two years. The first-gen ROG Phone launched in June 2018 while the current-gen model was unveiled in July 2019 and started selling a month later.

With only a month or two between today and these timelines, rumors of the ROG Phone 3 are already beginning to pile up. Of course, Asus is expected to keep on with the top-end hardware we’ve seen in the ROG Phone 2 and its counterpart.

The company is also expected to further tailor the ROG Phone 3 towards meeting the requirements of hardcore mobile gamers. Things like Snapdragon 865 chipset and pre-installed Google Stadia support have been brought up already.

Asus ROG Phone arrived priced at $900

While at it, the company should also keep supporting existing models through regular software updates that fix bugs and add new features.

Not long ago, for instance, the ROG Phone II picked up a new software update. The package bundled lots of bug fixes alongside a new February 2020 security patch.

Not the latest, sure, but it seems Asus sneaked the much-awaited VoWiFi calling feature in there as well. The changelog didn’t mention anything to do with ROG Phone 2 VoWiFi support, but we are seeing multiple reports confirming that the feature is indeed enabled after this update.

Unfortunately, though, it’s currently limited to Reliance Jio. Airtel users should get it at some point, though no one knows when this will happen. Jio subscribers can enable VoWiFi calling by going to Settings > Network and internet > Mobile network > WiFi Calling.


One ROG Phone 2 owner seems to be experiencing a strange issue with the VoWiFi feature. Apparently, the device does show the VoWiFi icon but WiFi calling doesn’t actually work because the phone drops to LTE after a few seconds on VoWiFi.

What’s even more baffling is that their VoWiFi works when Airplane mode is enabled, meaning they can actually make and receive WiFi calls in this mode. But turning off Airplane mode disables VoWiFi. See the screenshots below (left on Airplane mode and right on normal mode).

Another user also points out that the overheating issue seems to have been taken care of. Players of Call of Duty also seem to be enjoying a fix for the black screen issue as well as improved battery life, among other improvements.
