What is VoLTE and Benefits of Using It?

If you are a VoLTE user or planning to switch to the service, you might have hit the jackpot with this article. Continue reading this article to know everything about VoLTE ranging from its benefits and importance to limitations.

What is VoLTE?

Voice over Long-Term Evolution is referred to as VoLTE. It is a digital packet voice service that is supplied over IP over an LTE access network and uses IMS technology. Voice calls made over the 4G LTE network are known as VoLTE calls. In comparison to standard voice network calls, they have better audio quality. You can talk and use 4G LTE data simultaneously with this service, and you can hold conference calls with up to six participants. The industry has concluded that voice calls over LTE are the next step in voice services for mobile networks that use LTE radio access technology. For operators like OEMs, network suppliers, partners, and consumers, this service is valuable. Now that you understand what is VoLTE, let us move forward with benefits of using this service on mobile and more such helpful stuff.

Difference Between VoLTE and LTE (Long Term Evolution)

Here are the differences you need to know between VoLTE and LTE:

It is a system for data communication. It uses data communications to get around LTE.
It consists of the network’s services. It is a kind of network which exists.
It continuously offers simultaneous voice and data call services. It might or might not be able to offer voice and data call services simultaneously.
It permits HD-quality phone calls while utilizing data services. The voice calling quality is poor if data and voice calls are supported simultaneously.
While making phone calls, the data connection is not turned off. While making phone calls, the data connection is turned off.
Call connections are made more quickly if both users are on VoLTE. Slower call connection between two users
To make video calls, no further software is needed. To make video calls, you need third-party software like Skype or WhatsApp.

What is the Need of VoLTE?

For packet-switched 4G, Wi-Fi, and 5G networks, VoLTE serves as the cornerstone for expanding mobile voice and communication services. Using the IP Multimedia Subsystem is the standard mobile network technology for allowing worldwide compatible voice and communication services (IMS). The vast majority of customers actively upgrade their phones to ones that support VoLTE networks. This service is more dependable, particularly when traveling, thus switching is a wise move. Additionally, there is a need of this service because it provides high-definition speech quality that gives the impression that you are speaking to the other person in person.

Is It Good to Enable VoLTE?

By enabling this service, you can get better call quality and utilize the internet simultaneously to play games, browse the web, or scroll. The majority of contemporary smartphones, including iPhones and Android phones, have automatic VoLTE enabled. This service is strongly recommended because it is essentially packet-based voice services, which all carriers are moving toward because of improved bandwidth efficiency. This service is required if you wish to keep using high-definition voice services. Is it good to enable VoLTE? Will figure it out in a while.

Note: Smartphones do not have the same settings options and they vary from manufacturer to manufacturer, ensure the correct settings before changing any. The below steps may vary depending on the device you use. The following steps were performed on Mi A1 device.

How to Enable VoLTE on Your Mobile?

VoLTE support is increasingly a need, not an option, as carriers discontinue their older networks. You’ll soon find that making and receiving calls will become more and more challenging without it. And you might miss out on the benefits of using this service because of this, we’ll demonstrate how to enable VoLTE on your Android mobile.

How to Turn Off VoLTE

More and more smartphone owners want to know how to turn off VoLTE. The reason behind that is they have seen that phone calls cause their mobile phone to use more battery. Or that the phone’s connection keeps dropping when the 4G / LTE coverage is poor. They also understand that this service is the root cause of all these issues. Given all of this, it is worth considering how to turn off this service on Android smartphones.

1. Follow Steps 1-3 as mentioned in the above section.

2. Go to Advanced and ensure to toggle off Enhanced 4G LTE Mode.

Benefits of Using VoLTE on Mobile

It is a digital packet technology that leverages 4G LTE networks to transport data and route voice traffic. For high-speed wireless communications in gadgets like smartphones and data terminals, this voice service is the norm. LTE is a networking technology that only supports data; therefore, this service offers improved call quality, better service, and the ability to use voice and data at the same time. There are countless benefits of using this service on mobile some of which are mentioned below.

  • The benefits of sending information via the 4G network are obvious. Greater informational speed and preferences for the advantages that this service will also experience.
  • In normal scenarios, the pressure technique uses an 8kbps codec; however, with this service, the codec might contain 13kbps despite a more modern pressure strategy. Additionally, the recurrence range will increase from 300-3400 Hz to 50-7000 Hz. This results in a call that is much clearer than a typical versatile call.
  • Utilize new features like video calling, call transfer between your own devices while using multiple devices, multiple numbers on the same phone, etc. to innovate and secure add-on profits with tailored solutions.
  • These services have a more modest energy consumption than VoIP services like Skype since they use less battery power. It consumes far less energy.
  • It can be used through the 4G network, but we can also use it through any Wi-Fi association, resulting in savings in the speed at which we can transmit information.
  • It employs a native dialer with high-quality voice calls that are built on VoLTE along with business and enterprise collaboration features that are also available to enterprise users.
  • On top of the network, it provides unified communication services with business collaboration features.

Hence, these were benefits of using VoLTE on mobile device.

Limitations of VoLTE

Since we already highlighted how to turn off the service, its importance, and benefits of using this service, let us get down to its limitations. After all, not everything can be happy-go-lucky.

  • Investment in network-wide IMS is necessary. This means that it won’t be available everywhere and that roaming might be difficult for a while.
  • The user won’t be able to utilize the device to make calls or access the internet if there isn’t a data connection or 4G signaling nearby.
  • VoLTE calls can only be made between customers of the same administrator; for example, the calls between different administrators are not possible.
  • Only two VoLTE-compliant handsets can communicate via HD voice calls. When a VoLTE device calls another network-compliant device, regular call quality—rather than HD quality—can be obtained.
  • Price variation. Let’s switch to a different technology now that we are accustomed to the flat charge for calls. These calls use the data network. As a result, the section of our invoice that deals with the usage of data also includes the collection of such calls.
