[Other] VoLTE-The Ultimate HD Calling Experience!

Hello, Mi Fans!
In this thread, we will learn about Voice over Long-Term Evolution (VoLTE) and the craze for the VoLTE started in India from last few months ago. It is just another way of calling but through the Internet. Instead of routeing the calls over standard Internet protocol, VoLTE calls are delivered over a mobile 4G LTE broadband network. In order to make use of this, the user needs just two things -VoLTE supported smartphones and network. It has some advantages and bit of disadvantages as well. So please concentrate your mind to read this thread and get deep knowledge about this.

What are the benefits of VoLTE?
Superior call quality -  The big advantage of VoLTE is that call quality is superior to 3G or 2G connections as far more data can be transferred over 4G than 2G or 3G. Up to three times as much data as 3G and up to six times as much as 2G to be precise, making it easier to make out not only what the person on the other end of the line is saying, but also their tone of voice. Essentially it’s an HD voice call and it’s a much richer experience overall. Improved coverage and connectivity - VoLTE can connect calls up to twice as fast as the current methods and as 2G and 3G connections will still be available when there’s no 4G signal it simply means that there’s greater mobile coverage overall, as currently places with a 4G signal but no 2G or 3G means that one you can’t make or receive calls.

You might think that would be a rare occurrence, but some of the frequencies that 4G operates on, such as the 800MHz spectrum, have far greater reach than 2G or 3G spectrum, so you’ll be able to get signal further away from a mast or in buildings which other signals struggle to penetrate. Indeed, Three is fully relying on its 800MHz spectrum for VoLTE calls.

However, while 2G and 3G services would likely remain they wouldn’t be as necessary as they are now and much of the spectrum used for 2G, in particular, could potentially be repurposed to increase capacity on 4G networks.

Better Battery Life - Anyone who currently uses 4G could also find their battery life increased with VoLTE, as right now whenever you make or receive a call your phone has to switch from 4G to 2G or 3G, since 4G calls aren’t supported (other than on Three Super-Voice) and then once the call is finished it switches back again. All that switching, plus the need to search for a different signal each time, can give the battery a significant hit.

Video Calling - It’s also theoretically possible to make video calls over 4G, much like a Skype call except you’d just use your mobile number and be able to use the regular dialer and call interface, so you can make and receive video calls from anyone else with VoLTE, rather than relying on separate accounts.

In fact, you may have noticed that Skype and other existing video calls services often seem to have the superior audio quality of voice calls. That’s because like VoLTE they use more data as part of a similarly named VoIP system, so you can expect your voice calls to start sounding more like Skype calls, but they won’t hit your battery life as much as Skype does.
As VoLTE is tied to data it could also mean that you won’t have to worry about how many minutes you use, as everything will fall under data use.
Are there any limitations of VoLTE?
Initially, there are a few. For one thing in some implementations, it only works if both the device making a call and the one receiving it support VoLTE, so in the early days you might find yourself quite limited in terms of who you can actually use it to contact. Depending on how the networks set it up there also may or may not be network interoperability at first, so it’s possible that initially, you may only be able to use VoLTE to call people on the same network as you.

VoLTE also potentially requires both participants on the call to have 4G coverage. As that’s not yet as widespread as 2G and 3G it means that VoLTE calls won’t always be available and if someone moves out of 4G coverage during the call there’s a chance that the call will be dropped.

How do I know if my phone supports VoLTE?
Some of them who bought the mobile just before the revolution of 4G won't be having VoLTE feature in the smartphone in case of mid-ranger and lower end version. If you’re using a 3G handset then you’ll definitely need to upgrade, but if you have a newer 4G enabled one then it might work with VoLTE (though it will require a software update first).

Frequently Asked Questions.
Q -1: Can I convert my non-VoLTE 4G phone into a VoLTE-enabled one?
A: While some 4G phones inherently do not have VoLTE capability due to hardware limitations, others can have VoLTE features activated through a firmware (software) update that handset makers release from time to time. There are other, unapproved ways of activating VoLTE feature in a compatible phone through methods such as rooting but these would typically void the warranty.

Q -2: What happens if I am in an area where this is no data signal?
A: VoLTE phones can make calls even if there is no LTE/VoLTE signal on the phone as long as it catches adequate network signal.

Q -3: Do all 4G phones have VoLTE?
A: No. Not all 4G (LTE) devices have the capability to transmit voice over LTE.

The VoLTE service is capable of offering superior call quality, faster call set-up and rich communication service but it’s not working on all phone.  
How to check your phone support VoLTE?
1st Method:
If you want to check VoLTE supported smartphone list just click here

2nd Method:
In this method, we are going to use an App called VoLTE checker. This is the best App to check out your smartphones supports which terminology.
  •         Firstly, Download & Install VoLTE Checker App on your Android smartphone - Click here to download
  •         Open the App and turn on your data connection [Mandatory Step].
  •         Now it will start a process, it may take few seconds.
  •         After the process is completed it will show you whether your device is compatible with LTE or VoLTE.
  •         If your device supports VoLTE then the App will show a tick symbol [✓] with green screen.
  •         If this App shows a red screen with "Oh No" message then your 4G device supports LTE or indirectly it does not support VoLTE.
  •        That's it you are done. You have successfully found out which technology your device is belonged to.

Now you have basic knowledge about VoLTE !!! Please share your feedback in reply.
