And LTE is also widely considered the 4th generation of networking technology, which stands for the “4G” designation. LTE is the protocol over where data is being transferred, and at the now it is the fastest and most available data transfer platform for all customers. It’s also fast becoming and the most dominant technology. Over the past couple of years, devices have been phasing out their older 3G networks in favor of LTE. Some stats were saying the 3g network is about to dismiss by the end of 2018.

LTE vs VoLTE Major Differences

  • VoLTE or voice over LTE which makes you use voice calls, this quality will never ever reduce even if your data is turned on
  • Where are in the LTE support voice quality reduces with your device data turned on.

That is a very short difference between LTE vs VoLTE, here I am giving complete info by considering all aspects in LTE vs VoLTE. Here comes the very long description on LTE vs VoLTE Major Differences

What are the major benefits of VoLTE in LTE vs VoLTE?

Premium call quality – The major advantage of VoLTE support is that it’s premium call quality which is superior to any 3G or 2G device connections as more data can be sent over 4G than 3G or 2G. You will get an HD call service so it’s by far better, in fact, three times better than 3G connection and six times better than 2G connection. You will get a crystal clear quality and the same follows to the person on the other end. This is the major difference in LTE vs VoLTE

Improved Connectivity and Coverage – VoLTE which can also connect voice calls as quickly as possible to be precise up to two times faster connection than present 2G or 3G connection methods. When there is no 4G signal it means that there will be greater connection signal overall.

Better battery life – Yes another major difference in LTE vs Volte, who uses 4G their cell phones 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 cells 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. This means VoLTe got the best battery life although it uses much data compared to LTE. So this is undoubtedly the major difference in LTE vs VoLTE

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. Video calling or voice calling is the one-word difference in LTE vs VoLTE.

  33. Shravan ji, one more major difference between LTE and VoLTE is- in VoLTE phones, you can receive/voice call from your Jio Sim even with your 4G net off. But in LTE phones, you cannot receive/ voice call if your 4G net is off. And secondly, VoLTE will be seen written above on the screen where Sim range is showing. In LTE phone, it will show only 4G or LTE (it will not show VoLTE). Can you suggest, is there a way out so that my Lenovo K5Note (3 GB RAM) show VoLTE?
