What is VoLTE and How To Turn Off VoLTE Calls?

In this post, we will attempt to clarify the differences between 4G LTE and 4G VoLTE, the benefits and drawbacks of VoLTE, and how to enable or disable VoLTE calls on iPhone or Android phones.

4G LTE vs 4G VoLTE

Before moving on to VoLTE, we’d want to clarify the distinctions between 4G LTE and 4G VoLTE, as well as which one you should select.

What is 4G LTE?

4G refers to the fourth generation of mobile communications technology, while LTE stands for Long Term Evolution.

Cellular network operators may provide high-speed data to any 4G-enabled device using 4G LTE communication technology.

A 4G connection is 3 to 6 times faster than a 2G or 3G connection.

It is, however, simply a data-based protocol. You will only be able to use data for web services if you connect to the  LTE.

You may use 4G LTE to access the web and use apps that require an Internet connection, among other things.

As a result, extra services such as phone calls and SMS messages will be offered over 2G/3G technologies rather than the LTE network.

This means that if you do any of these activities, your smartphone will automatically switch to a 3G or 2G network.

All phone calls and SMS messages will be transmitted over 2G or 3G networks.

The disadvantage of 4G LTE is that you will be unable to make calls while traveling in rural areas because there will be no 2G/3G network to rely on.

However, this is highly unlikely because 2G/3G networks are more prevalent than 4G networks in most regions of the world.

What Are VoLTE Calls?

VoLTE is an acronym for Voice Over Long Term Evolution, which is a fourth-generation (4G) mobile communication technology.

Voice is carried through an LTE network under this VoLTE technology, ensuring crystal-quality voice and video conversations.

In addition to typical data use, VoLTE allows voice calls to be made using internet bandwidth.

It’s essentially phone conversations, but instead of using traditional mobile phone networks, it uses data.

Unlike 4G LTE, all calls, SMS, and web browsing under VoLTE will be delivered only over data channels.

Your Internet data plan will be utilized to make phone calls, send SMS messages, and browse the web. It indicates that all services, including browsing, voice calls, SMS, and so on, will be delivered via data/Internet.

You may also use this to make high-definition voice calls over the internet (similar to WhatsApp voice calling, which makes calls over the IP network).

Adopting the most modern VoLTE technology over LTE is useful for a variety of reasons. The following are a few of the most prevalent benefits.

Advantages of VoLTE Services

VoLTE is a high-speed voice communication technology that is clearer than 3G and 2G technologies.

If your phone supports VoLTE, you can utilize both data and voice services at the same time.

Other benefits of VoLTE services include the following.

1. HD Quality Calls

As previously stated, VoLTE allows for smooth high-definition calls.

VoLTE call quality is about three to six times better than that of earlier mobile network generations such as 2G or 3G.

2. Good Battery Backup

Because VoLTE allows customers to enjoy data and voice at the same time, switching from 4G to 3G and vice versa is no longer necessary.

This switching uses a lot of battery power, reducing the battery backup duration significantly.

As a result, as compared to prior generation networks, a user receives more battery life for their smartphone from a VoLTE network.

3. Better Connectivity

4G networks have more coverage than 2G or 3G networks. Furthermore, VoLTE 4G calls connect at a quicker rate than previous-generation calls.

The VoLTE frequency band is capable of overcoming even the most massive obstacles, something that previous generations struggled with.

Because VoLTE provides better network coverage and connection, the access network is broader, more dependable, and extremely fast.

4. Multitasking

We’ve already said that on the VoLTE network, voice calls and data consumption are allowed at the same time.

Another advantage of VoLTE is the ability to multitask. Your 4G network degrades to 3G during conversations without VoLTE, preventing you from accessing fast internet.

You may surf the web, download media, and do other things during your VoLTE sessions.

5. VoLTE Enables Video Calling

You can even make video calls via VoLTE while using very little data and without using any third-party applications like Skype.

Video calls are included in the calling interface of 4G VoLTE phones.

Furthermore, 4G VoLTE saves battery life during video calls. Switching between voice and video calls is a quick and simple process.

Disadvantages of VoLTE

Although there are several advantages to using VoLTE services, there are some drawbacks as well.

1. Requirement of VoLTE-Enabled Mobile

To use VoLTE services, your device must be VoLTE-compatible. Many smartphone users do not have VoLTE-enabled models.

While some smartphones could get the service as part of a software update, many older handsets will not.

While VoLTE calls have higher quality, they are only available between two VoLTE-enabled smartphones. If one device supports VoLTE but the other does not, the call will be of standard quality rather than high quality.

It’s worth mentioning in this context that several providers have already stopped 3G services, leaving users with no other choice.

So, if you want better connectivity and call quality, upgrading to a VoLTE-enabled smartphone is a wise choice.

2. Availability of 4G Coverage

VoLTE calls require either a 4G signal or a Wi-Fi connection (which is technically a distinct technology called VoWiFi, although it is similar) to function.

If you don’t have 4G coverage, you won’t be able to make HD calls or access the internet.

Enable or Disable VoLTE on iPhone

For iPhone users, the option for VoLTE on or off may be found under the Cellular Data settings.

In Settings > Cellular > Cellular Data Options, tap Enable LTE. Alternately, navigate to Settings > Mobile Data and select Enable LTE.

To turn off VoLTE repeat the same process and disable the LTE switch.

There are three choices available to iOS users:

Off: Disables LTE.

Voice and Data: This enables phone calls as well as cellular data access through LTE.

Data Only: This allows you to utilize your cellular data but not make phone calls via LTE.

Choose between VoLTE and LTE depending on your requirements.

Enable or Disable VoLTE on Android

Look for the VoLTE icon alongside the call networks on the top notification bar to see if VoLTE is enabled or not.

The configuration settings interface on Android phones may change based on the manufacturer and version of Android.

However, in general, we can follow the procedures outlined below.

Go to Settings and look for Connection > Mobile Networks (This may vary depending on your smartphone). Choose your primary SIM card. To enable or disable VoLTE, locate the toggle button.


A lot of people are asking whether is LTE better than VoLTE.

Simply we can answer this question. You may use LTE without VoLTE, however, it is not possible to provide VoLTE without LTE.

4G VoLTE is a more refined and improved version of 4G LTE.

If you’re on the lookout for a new phone, be sure it supports 4G VoLTE.

Frequently Asked Questions

How does VoLTE work with Wi-Fi Calling?

When LTE coverage deteriorates and Wi-Fi is available, VoLTE calls will be converted to Wi-Fi calls. Wi-Fi must be switched “ON” for this automatic transfer to take place. This implies that if you have Wi-Fi Calling enabled on your smartphone, it will only be used if cellular coverage in your location is poor. If you are on an active VoLTE call and the coverage begins to degrade, the call will attempt to transfer to Wi-Fi when the device is linked to a strong Wi-Fi signal.

Will VoLTE call count against my data plan?

No, data used by VoLTE calls is not included in data plan restrictions.

How do I know that VoLTE is enabled on my mobile?

When VoLTE is enabled, the VoLTE or LTE icon may appear in the status bar of most smartphones that use a 4G SIM card.
