Google blocks Android hack that let Pixel users enable VoLTE anywhere

TL;DR

Google’s October 2025 update has broken the Pixel IMS app, a tool many used to enable VoLTE and VoWiFi on imported Pixel phones in unsupported regions.
The app exploited a loophole that allowed it to override carrier settings, which Google has now patched and designated as a high-severity vulnerability (CVE-2025-48617).
Fortunately, a new workaround has been discovered to enable VoLTE in unsupported regions, but users who want VoWiFi must now either root their devices or wait for Google to officially expand carrier support.

Pixel phones are beloved for their many unique software features, but their limited availability prevents many people from buying them. While Google has made strides in expanding access, Pixels still aren’t sold in nearly as many countries as iPhones or Samsung Galaxy devices. This leads many fans to import Pixel phones from other markets, a move that can unfortunately break crucial calling features like VoLTE and VoWiFi.

VoLTE (Voice over LTE) is the feature that routes voice calls over a 4G LTE connection, a crucial function now that carriers worldwide are phasing out their 2G and 3G networks. Without it, you might not be able to make phone calls at all on many modern networks. Similarly, VoWiFi (Voice over WiFi) handles Wi-Fi calling, routing calls over a Wi-Fi network instead of cellular — a handy feature when you’re in a building with poor signal.
