How do I enable VoLTE (4G voice calling) on my device?
To continue accessing the network and being able to make voice calls after 3G shut down on 28 October 2024, devices need to support VoLTE (Voice over LTE/4G voice calling/HD calls). Here are the steps to enable it:
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.
Android:
- Open Settings > System > Software update (path may vary)
- Check for updates and install any available
iPhone:
- Go to Settings > General > Software Update
Enable VoLTE in settings
Once updated, you'll need to turn on VoLTE in your mobile network settings. The path differs by manufacturer:
Android:
- Open Settings > Network & internet > Mobile network
- Look for an option like "Enhanced 4G LTE Mode" or "VoLTE" and turn it on
iPhone:
- Go to Settings > Mobile Data > Mobile Data Options
- Tap "Voice & Data" and select the VoLTE enabled option (e.g. 4G, VoLTE On)
Samsung:
- Tap Settings > Connections > Mobile networks
- Toggle VoLTE calls
Huawei:
- Tap Settings > Wireless & Networks > Mobile Network
- Toggle VoLTE calls
OPPO:
- 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)
Nokia:
- Tap Settings > Network & Internet > Mobile Network > Advanced
- Toggle Enhanced 4G LTE Mode
Motorola:
- Settings > Mobile network > Mobile data
- Toggle VoLTE calls

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 after the 3G shutdown, 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 after 3G was switched off.
