VoLTE: The Most Emerging Technology in LTE Domain

Globally most of the mobile service providers already on LTE or deploying LTE on their network. As far as we are concerned about Indian landscape, here the big players all are offering LTE. 

As the global trends show the universal acceptance of VoLTE (Voice over LTE) – for offering voice calls over IMS (IP Multimedia Subsystem) architecture based LTE networks, here in India apart from BSNL, all serious players (Airtel, Reliance Jio, Vodafone/Idea) are launching VoLTE or already launched it. Reliance Jio is completely on VoLTE, while Vodafone is offering it in ten circles, followed by Bharti Airtel in nine circles. Idea Cellular has opened the VoLTE to its employees, which is expected to go official for the users in some circles very soon, but there’s no word on the same.

Reliance Jio is completely on VoLTE, as the telco doesn’t have any legacy voice network on 2G/3G. Others telcos have the Circuit Switched Fall Back mechanism based voice on 2G/3G and data on LTE initially, later they are moving on to VoLTE.

Why is VoLTE gaining momentum in the country? The reason is simple – better spectrum efficacy, refarming of spectrums that is being used on 2G/3G networks, better services like HD voice and video calling are the main reasons. 

FAQ to Jio 4G/LTE Voice Services

I already have been using JIO's digital services over Jio MiFi device since August end. I did not have much interest to get a JIO SIM for mobile as I did not like the idea to stand in a queue for long time to get a free SIM.

I had two barcodes - on Redmi Note 3 and Honor Holly and found that Honor Holly's bar code was stolen away already. So I prompted for using the barcode generated on RN3.

To my surprise the queue has been vanished and thanks to JIO's e-KYC solution the process is very fast.


1. What is JIO's e-KYC solution for SIM activation?

Jio makes the subscribers's document submission and activation of the connection on the SIM completely digital - it's superfast digital processing service by JIO e-KYC solution.

What you need to get a JIO connection in 10 minutes or less? Get a 4G smartphone, download MyJio app and generate the barcode. Now walk into any Reliance Digital store with your Adhaar Card and rest will be taken care of by the stuffs there. You will get a JIO SIM in few minutes after verification and submission of your application form online.

In my experience it hardly takes 5 minutes to complete the whole procedure.

Verizon Aggressively Backing for VoLTE before Winding up Traditional Voice

American telecom giant Verizon is working hard to make Voice over LTE (VoLTE) a default feature for its all customers. Presently worldwide carriers are shutting down 2G networks to make room for LTE deployments. Verizon is also walking to it – the company has plans to phase out its entire CDMA network by 2021. But before that they need to have a robust 4G network running.

Now Verizon’s VoLTE feature is an opt-in feature where customers need to select this feature on their VoLTE enabled smartphones. David Small, executive vice president of wireless operations at Verizon Wireless informed that more than 4 million customers are using this feature, which will be the default voice option to all customers in due course.

Verizon has launched VoLTE as Advanced Calling 1.0 - the initial version of VoLTE. Currently they have 25 smartphones supporting VoLTE.
