How to Enable VoLTE on Your Samsung S7 Edge for Off-Network Calls with Jio in India

The VoLTE (Voice over LTE) feature for Samsung S7 Edge is designed to provide high-quality voice calls over the 4G LTE network, enabling seamless calls even when you are not connected to the internet. However, if you own an S7 Edge purchased outside of India, you might face limitations with VoLTE and Jio's services. This guide offers a comprehensive solution on how to enable VoLTE on your Samsung S7 Edge for off-network calls with Jio.

Check Compatibility

First, it's essential to check compatibility. Ensure that your Samsung S7 Edge is compatible with Jio's VoLTE services. Generally, Jio works well with most unlocked versions of the S7 Edge. However, if your phone is an international model, you may need to update the firmware specifically for the Indian market.

Set Up SIM Settings

Insert your Jio SIM card into your Samsung S7 Edge. This step is crucial as it ensures your device is set up to recognize the Jio network. Go to Settings -> Connections -> Mobile networks -> Network mode. Set it to LTE/3G/2G auto connect. This setting ensures your phone automatically selects the best available network when in range.

Enable VoLTE

Go to Settings -> Connections -> Mobile networks. Look for an option labeled VoLTE calls or Enhanced 4G LTE Mode. If the option is available, enable it. This feature will allow you to make voice calls over the 4G LTE network.

Adjust APN Settings

Go to Settings -> Connections -> Mobile networks -> Access Point Names. Ensure that the Jio APN is correctly set. If it's not, you will need to add a new APN with the following settings: Name: Jio APN: ( varies by service provider ) MMSC: ( varies by service provider ) MMS Proxy: 10.224.0.1 MMS Port: 80

Save the changes and select the newly created APN.

Restart Your Phone

After making these changes, restart your phone to ensure the settings take effect. This step is necessary to apply the new configurations and ensure smooth operation.

Check for Updates

Finally, make sure your phone's software is up to date. Go to Settings -> Software update and check for updates. Having the latest software can help improve compatibility and performance.

Additional Notes

VoLTE requires an active data connection, so ensure that your mobile data is enabled before attempting to make calls. If VoLTE is still not working, it may depend on your network settings or restrictions in your region.

In cases where your phone is an international model and the standard settings do not support VoLTE for Jio, the only way to enable it is to install the firmware provided for the Indian version of the S7 Edge. You can do this either by rooting your phone and installing the new firmware yourself or by taking it to a mobile store that will perform the update for you.

It is also advisable to contact Jio customer support for any additional assistance or specific instructions related to your device.
