Samsung Galaxy Grand Prime

4G is the latest mode of transferring data at lightning speed. But it has a disadvantage that it can't transfer voice data in this mode. Many companies which have 2G and 4G spectrum, switch from 4G to 2G for voice calls. But other companies like Jio who doesn't have a 2G spectrum has introduced Voice over LTE (VoLTE). This feature enables a user to use 4G data along with calling feature without switching to 2G mode.

VoLTE is an HD voice calling Service that run on 4G LTE rather than the 2G/3G network. Currently, we are using 2G/3G. Originally LTE was completely IP Cellular System for carrying Data. If you are making a call from LTE Network, the Operators would be able to carry the voice either by reverting to 2G/3G technologies.

In the 4G phone when we use Jio SIM, we can do a call and can also use the Jio calling app. But in VoLTE when we use the Jio SIM, we can do calls without Jio calling app. In VoLTE the net speed is very fast.

4G network you can use with any SIM like Airtel, Vodafone, etc. But to use Reliance Jio, you need to have VoLTE means Voice over LTE (4G) and this supports voice calls and internet.

4G was designed to provide higher data transfer rates, while VoLTE is specifically targeted at improving the quality of voice calls.

Yes, one who's still using 3G must switch to 4G. Reasons:- 1. Latest technology. 2. Lightening fast technology. 3. Cheapest rate for data. 4. Nominal charges for voice calls. 5. The companies are providing better plans to attract customers.
