How do I enable VoLTE (4G voice calling) on my device?

To continue making voice calls after the 3G network shutdown on 31 August 2024, your device needs to support VoLTE (Voice over LTE/4G voice calling/HD calls). Here are the steps to enable it:

  1. Check for software updates

    First, ensure your device is running the latest software version from the manufacturer. Software updates often enable new features like VoLTE.


    • Open Settings > System > Software update (path may vary)
    • Check for updates and install any available


    • Go to Settings > General > Software Update
  2. Enable VoLTE in settings

    Once updated, you'll need to turn on VoLTE in your mobile network settings. The path differs by manufacturer:


    • Open Settings > Network & internet > Mobile network
    • Look for an option like "Enhanced 4G LTE Mode" or "VoLTE" and turn it on


    • Go to Settings > Mobile Data > Mobile Data Options
    • Tap "Voice & Data" and select the VoLTE enabled option (e.g. 4G, VoLTE On)


    • Tap Settings > Connections > Mobile networks
    • Toggle VoLTE calls


    • Tap Settings > Wireless & Networks > Mobile Network
    • Toggle VoLTE calls


    • Tap Settings > Dual SIM (or 'SIM card and mobile data' on single SIM models) & Cellular Network
    • Choose SIM 1 or SIM 2 (just SIM on single SIM phones)
    • Toggle VoLTE Calls


    • Tap Settings > Network & Internet > Mobile Network > Advanced
    • Toggle Enhanced 4G LTE Mode


    • Settings > Mobile network > Mobile data
    • Toggle VoLTE calls
  3. Reboot your device

    After enabling VoLTE, restart your phone to ensure the new settings take effect.

If you don't see VoLTE options or have trouble, check your device manufacturer's support for model-specific instructions.

Enabling VoLTE will allow you to continue voice calling over 4G once 3G shuts down, while also accessing data simultaneously, as long as your device supports it. If your device does not have VoLTE capability then it will need to be replaced in order to be able to continue using the service once 3G is switched off.
