In recent times, mobile carriers have been implementing VoLTE (Voice over Long Term Evolution) phone calls for their customers, providing unmatched call quality and crystal-clear communication. However, not all users can avail themselves of this impressive feature, primarily due to not meeting the specific requirements.
The concept behind VoLTE is rather straightforward – it involves a shift from the traditional mobile voice network to a data network for making calls. As the name suggests, VoLTE stands for ‘Voice Over Long Term Evolution.’ Despite its benefits, carriers have not heavily publicized this option, leading many users to be unaware of its existence and potential. But fret not, we are here to guide you on how to make the most of this feature on your device.

You have to activate VoLTE on your mobile
VoLTE, or Voice over Long Term Evolution, has a distinctive feature: it utilizes 4G networks for voice communication during phone calls. While 4G networks have long been used primarily for internet browsing, they previously automatically switched to a 3G network when making calls. However, this has changed, and now VoLTE is available for calls, offering various advantages.
One of the key benefits of VoLTE is its improved coverage and enhanced energy efficiency, which leads to longer-lasting battery life. Additionally, the connection is faster, and call quality is significantly improved, ensuring seamless communication without interruptions. The best part is that there are no extra charges for using VoLTE; it comes as part of your contracted plan, allowing you to make the most of its features without any concerns.
To use VoLTE on your mobile device as a customer of a compatible carrier, follow the simple steps outlined below. However, before proceeding, ensure that your phone is updated to the latest operating system version. Once that is confirmed, continue with the following:

For Android devices:
- Open the settings on your device.
- Navigate to the ‘Mobile network’ or ‘Connections’ section.
- Choose your SIM card and access ‘Preferred network type’.
- Select the automatic option that includes all networks.
- Look for the ‘Use mobile data during calls’ option; if your carrier supports VoLTE, it will be available here.
For iPhone devices:
- Access settings and go to the ‘Mobile data’ section.
- Click on ‘Options’ and then ‘Voice and data’.
- Activate ‘VoLTE’ to start enjoying higher quality calls.
Note for iPhone models prior to iPhone 12: For these models, enable both the ‘VoLTE’ and ‘4G’ options. This will allow you to experience improved call audio quality. However, ensure that your carrier offers VoLTE service, as the option will remain disabled if it is not available.
Your operator must activate it on your line
Indeed, some users have faced an issue where the VoLTE feature remains disabled, even though their carrier supports it. This problem arises when the company fails to activate VoLTE correctly on the user’s mobile line, leading to the feature being unavailable.

If you encounter this situation, there is a straightforward solution. Simply visit the technical service of your mobile operator and request them to activate VoLTE on your line. Once they have made the necessary adjustments, restart your smartphone and then proceed with the steps mentioned earlier to enable VoLTE on your device. This should allow you to fully utilize the benefits of VoLTE, such as improved call quality and energy efficiency, without any further issues.
By taking this proactive approach and ensuring that VoLTE is correctly activated on your mobile line, you can enjoy seamless and enhanced communication experiences through the power of this technology.
