How VoLTE Works and How to Enable it on Android and iPhone

VoLTE (Voice over LTE) is a technology that revolutionizes voice calls by enabling them to be transmitted over 4G LTE networks. But how exactly does VoLTE work and how can you enable it on your Android and iPhone devices?

The working mechanism of VoLTE involves converting voice calls into digital packets and transmitting them over the LTE network. The process consists of the following stages:

  1. Initiation: When you initiate a voice call on your phone, it sends a signal to the network indicating your intention to make a call.
  2. Call setup: The network establishes a dedicated voice channel for the call, ensuring a seamless connection. This eliminates the need to switch between different network modes, allowing for faster call setup times.
  3. Voice transmission: During the call, your voice is converted into packets of data and sent over the LTE network to the receiver’s device.
  4. Call termination: Once the call is completed, the network releases the dedicated voice channel, freeing up network resources for other users.

Now that you understand the working mechanism of VoLTE, let’s explore how you can enable it on your Android and iPhone:
