What is VoLTE?
In order to understand how to convert LTE to VoLTE in Kolkata, we must understand what is VoLTE. VoLTE stands for voice over LTE and it’s more or less exactly what it says on the tin. It’s voice calls over a 4G LTE network, rather than the 2G or 3G connections that are usually used. We tend to think of 4G as mostly being about downloading, streaming, and web browsing, and indeed that’s primarily what it’s been used for so far, but it can also be used to improve calls.
What is LTE?
LTE (Long Term Evolution) is the project name given to the development of a high-performance air interface for cellular mobile communication systems. It is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks. While the former generation of mobile telecommunication networks is collectively known as 2G or 3G, LTE is marketed as 4G.
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. This is why you might want to convert LTE to VOLTE in Kolkata.
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. So you might need to convert LTE to VOLTE in Kolkata.
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.
What is the Difference Between 4G LTE & VoLTE?
LTE vs VoLTE What are the Major Differences?
LTE which stands for Long Term Evolution
VOLTE which stands for Voice Over Long Term Evolution
LTE means 4G. It comes with a high-speed Internet connection which supports CAT 4.
VOLTE means HD Voice call, it’s better and clear than a normal call and it uses your device data for better call quality
These both are so different, so there are so many devices that actually support 4G LTE but don’t support VOLTE. No one can interchange both of them. So you might want to convert LTE to VOLTE in Kolkata
Can LTE be Converted to Volte?
The answer to this question has two facets –
1. The handset in use
2. The backend cellular network.
Handset in use –
There are two types of LTE handsets:
Type 1: Handsets that are capable of sending both voice and data over the LTE network, and –
Type 2: Handsets that use LTE to only consume data, but the voice communication remains on 2G/3G.
In technical jargon, Type 1 handsets are known to be Voice over LTE (VoLTE) capable. These phones implement the GSMA IR.92 and IR.94 standards which define the characteristics a VoLTE handset must support.
Type 2 handsets are also referred to as “Data-only” LTE phones. Such phones, even though being LTE capable can use LTE 4G only for data. For some handset manufacturers, it is possible to “upgrade” such phones through a firmware update to VoLTE phones, in other words, it can be converted from LTE to VOLTE in Kolkata. However, this is not true for all handset manufacturers.
Backend Network –
Just because a phone supports VoLTE, it does not mean that voice will always go over the LTE packet network.
The 4G packet core network has a network element known as the MME (Mobility Management Entity). When the phone tries to “attach” to the network, the MME sends back an indication to the phone that alters its behavior.
There is a VPS bit (Voice over Packet Switched), which when set to “1”, tells the phone that the network is also VoLTE capable, and voice can be sent over LTE. However, if the phone does not support sending voice “as packets” over LTE (Type 2 described above), then voice services will not work over such a network. Type 1 VoLTE phones would work well when the VPS bit is set to 1.
Some networks also set the “CSFB Indicator”. CSFB stands for Circuit Switched Fall Back. This informs the handset that the network has a 2G/3G circuit-switched network as a “fallback” for voice services, and hence voice calls can use the legacy 2G/3G network, while data may continue over LTE. Hence, Type 2 data-only phones are best suited for networks that have CSFB.
