The ROG Phone 3’s latest update finally enables VoLTE on AT&T and T-Mobile in the US
The ASUS ROG Phone 3 recently received a new firmware with the version number 17.0823.2008.70, which introduced a “Bypass Charging” feature that lets you pass power from the charger directly to the phone instead of the battery. The build also fixes a number of display brightness related issues and bumps the Android security patch level. However, as it turns out, the Taiwanese OEM secretly enabled VoLTE support on US carriers like AT&T and T-Mobile with this update, but chose not to list the improvement in the OTA changelog for some reason.
Multiple users on Reddit’s ROG Phone 3 subreddit have corroborated that VoLTE starts working on AT&T after installing the latest update. The OTA is good for T-Mobile users too, as our Editor-in-Chief, Mishaal Rahman, has confirmed that the phone can now make use of VoLTE on T-Mobile without any extra configuration. This is no doubt an important advancement as more carriers move towards adopting VoLTE on their network.

For your information, it is possible to manually set the carrier-specific parameters on select ASUS smartphones — including the ROG Phone 3 — to unlock advanced IMS services like VoLTE on T-Mobile’s network if you have root access. Having said that, an official update is always preferable in this scenario, especially since not everyone wants to tinker with their shiny new gadget.
At the time of writing this article, the official announcement thread for this update is no longer up on ASUS’ ZenTalk Community. Perhaps the current implementation needs another coat of paint before ASUS is confident enough to announce it officially. If you want to sideload the new build anyway, you can download the full firmware from the link below.
