What is the function of volte? Is it necessary to open it?

VoLTE is called Voice over LTE, which means that high-definition voice calls need to be opened on 4G networks.

Now the carrier networks we choose are all 4G networks. But in fact, the 4G network is only used when data access services are used, and voice services have been maintained at 2G and 3G.

After the launch of VoLTE, all services will be carried out on the 4G network. Therefore, with the support of 4G network, the sound quality of both signals and calls will be much stronger.

VoLTE advantages:

1, the connection waiting time is shorter.

After opening Volte, you don't need to return to the 2/3G network from 4G to make a call, but it only takes 5-6 seconds or more for non-VoLTE. When opening VoLTE, both parties only need to connect the phone.

2. The call quality is clearer and more natural.

Then VoLTE phone introduced high-definition voice and video coding, and the voice quality was significantly improved.

3, data and call at the same time.

After opening this function, there is another advantage that the number of users can reach tens of thousands during the call, even if you have a phone call while swimming, it will not lead to disconnection.
