Hi, welcome to our community.
There could be several reasons why VoLTE is not working. Here are some troubleshooting steps you can try to resolve the issue:
1. Check network coverage: Ensure that you're in an area with good LTE coverage.
2. Enable VoLTE: Generally, you can find the VoLTE option on Advanced > Telephony > Telephony Mode. Make sure Telephony Mode is VoLTE and VoLTE is enabled on the same page.
3. Check network mode settings: Go to Advanced > Network > Internet page, make sure Network Mode is 4G Preferred, also try 3G Only for comparison if there is still 3G service in your area
4. Test with another VoLTE device: Insert the same SIM card into another VoLTE-compatible device, such as a smartphone, and observe if you can make and receive VoLTE calls. Pay attention to the network type displayed during the call (e.g., 4G LTE, 3G, 2G) to determine if the issue is specific to your device or the network.
Please provide results of above troubleshooting steps if you need further suggestions.
You may also contact local technical support for direct help.
Thank you and best regards.
