VoLTE stands for
Voice over Long-Term Evolution or
Voice over LTE. VoLTE offers the possibility to voice call via the
LTE/4G* mobile network.
Previously, 4G was limited to surfing the Internet. When it came to calls, your phone would automatically switch to 3G or 2G. You may recall a few seconds of delay before the recipient's phone rang. Thanks to VoLTE, that delay is gone.
On a 2G or 3G network, calls and data are separated and cannot work simultaneously. For example, during a phone call on a 2G network, any incoming text messages at that moment will only arrive after you’ve terminated your phone call. On a 4G LTE network, both calls and data work in unison, meaning that a text message will arrive instantly even during a call.
*The terms
4G and
LTE refer to the same technology and can be used interchangeably.
What are the benefits of VoLTE?
- Fast call set-up.
- High voice quality and reduced background noise.
- The phone remains in the 4G/LTE network during voice calls.
- You can use 4G/LTE data services, such as web surfing and tethering, while simultaneously making and receiving calls.
- When calling over LTE, you don't use extra data but call minutes. You pay for the voice call service, not the data you use.
