what is vo lte on my phone

VoLTE stands for Voice over LTE, which is a technology that allows voice calls to be transmitted over the LTE/4G mobile network. Previously, 4G was limited to surfing the internet, and when it came to calls, the phone would automatically switch to 3G or 2G. With VoLTE, the delay in call connection is gone, and both calls and data work in unison, meaning that a text message will arrive instantly even during a call. VoLTE can help improve call quality, and it may already be activated on your phone. If you have a modern phone, you are probably already using VoLTE, and all major U.S. carriers have rolled it out. To use VoLTE, you need an LTE-compatible phone, and your phone must be within the range of an LTE network. To turn on VoLTE, you need to turn on the cellular data setting on your phone, and on most modern smartphones, VoLTE is automatically active.
