    Sunrise VoLTE - 4G Network voice calling

    VoLTE allows you to make phone calls directly via the latest-generation 4G+ Sunrise mobile network using your LTE-capable smartphone.

    Prerequisites

    Activating VoLTE

    Here you will find the guide to activate VoLTE.

    Check if your phone supports VoLTE

    If you're not sure whether your phone supports VoLTE, check the following:

    1. During a call, a VoLTE symbol should appear on your screen. The 4G or 5G symbol should also remain visible. Depending on the device and operating system, the VoLTE symbol may vary, but it is often displayed as the text "VoLTE".

    2. If the 4G or 5G symbol appears on your phone but disappears during a call, VoLTE may not be enabled, or your phone may not support it.

    Billing

    VoLTE calls will be billed as normal calls according to your current subscription.
