What Is VoLTE And How To Activate It?

 If VoLTE is available on your carrier's network, this technology will result in clearer voice call quality. So what is VoLTE and how do you activate it?

What is VoLTE?

VoLTE stands for Voice Over LTE, where LTE means Long Term Evolution. As the name suggests, VoLTE is voice calls made over the 4G LTE network. This allows you to make calls over your LTE network rather than the "standard" network.

VoLTE makes voice calls clear with high quality. It also lets you use your Internet data to make calls apart from downloading or browsing the web.

Benefits of VoLTE

Benefits of VoLTE

Most smartphones now support VoLTE, and almost all network operators provide VoLTE support worldwide. If your phone doesn't support VoLTE, you can change your smartphone or wait for a software update that might bring this feature.

Also, if your smartphone doesn't support VoLTE technology, you might notice that you can't use data and voice at the same time. Here's how VoLTE helps.

When making VoLTE calls, you can use data to call and browse at the same time. VoLTE has been one of the best features to improve voice calls around the world. VoLTE comes with a lot of benefits. Here are some of the main advantages.

1. High Definition Call Quality

The most significant advantage of 4G VoLTE is better call quality. You can communicate clearly with users through voice calls.

While the call quality of previous network generations such as 2G and 3G lacked High Definition, 4G VoLTE provides three times better call quality than 3G and up to six times that of 2G.

2. Good Battery Life

You may have noticed that without VoLTE, your 4G network switches to 3G every time you place a call, causing the smartphone to use up more battery than usual. With VoLTE, your phone doesn't switch to 3G even when you're on a call, saving battery life.

3. Wider Coverage And Better Connectivity

You will be surprised to know that VoLTE calls can connect up to two times faster than 2G or 3G signals. Plus, 4G is widely available around the world now.

4G operates on the 800 MHz spectrum, which has wider coverage than 2G or 3G spectrum. This spectrum can even penetrate massive objects, which was difficult for previous generations.

So, even if you are in the basement or on the top floor, you will still have a network connection. Therefore, although VoLTE relies on this spectrum to provide better coverage and better connectivity, the available network is wider and more consistent.

4. Multitasking

Without VoLTE, your 4G network becomes 3G on calls which restricts you from using fast internet during the call. With 4G VoLTE, this is not the case.

Your 4G network stays the same and lets you use data between calls. You can surf the web, download files and more during a VoLTE call.

5. Video Calls Via VoLTE

You can even make video calls over VoLTE with very little data consumption. Usually, you have to download third-party apps like Skype, Google Meet, Zoom, etc. To make video calls.

But with 4G VoLTE, you don't need to install any other apps. Phones that are compatible with 4G VoLTE get support for video calls built into their calling system. In addition, 4G VoLTE saves battery on video calls.

How to Enable VoLTE?

Enabling and disabling VoLTE on smartphones is a simple process and requires nothing but your smartphone. The only requirement is that your phone must support 4G VoLTE.

Telecom companies and smartphones sometimes refer to VoLTE call as HD calls. Here's how to activate VoLTE on a smartphone.

How to Enable VoLTE

First, you go to Settings and search for Network & Internet (This may vary depending on your smartphone). Click on your Primary SIM.

Find the VoLTE toggle button and enable it. The VoLTE feature is now enabled.

VoLTE Service Limitations

VoLTE Service Limitations

While VoLTE calling provides high-definition calling, this feature is limited to calls only made between two VoLTE-enabled handsets. If one handset is VoLTE enabled and the other is not, then calls will be of standard quality and not HD.

2. Requires Internet

VoLTE calls require a data connection or 4G signal to work. Otherwise, you will not be able to make HD calls or use the internet.

3. Handset Support Required

To activate the VoLTE service, your device must be compatible. Many users do not activate the VoLTE service on their smartphones.

While some smartphones receive the service with the update, many older models are not compatible with VoLTE.


So what is VoLTE? VoLTE in a nutshell is a voice call made over a 4G LTE network. They have better audio quality than regular phone calls made over standard voice networks. VoLTE lets you make calls and use 4G LTE data at the same time.
