Following the public release of iOS 10.3 yesterday, Apple has updated its list of wireless carrier support and features by country to note a number of carriers that now support Wi-Fi calling and or VoLTE functionality.

Wi-Fi Calling, which enables calling over Wi-Fi connections when cellular coverage is limited, and the wideband, higher-quality phone calls enabled with VoLTE, are now available in 20+ new countries and carriers (full list below).

Among the new additions is Verizon in the US, which we noted yesterday added Wi-Fi Calling for iCloud-connected devices with yesterday’s iOS 10.3 release.

Some limitations apply by device and region (VoLTE is available only on iPhone 6 or later, for example), and you’ll likely require a carrier settings update that your device will prompt you for before accessing the new features.
