VoLTE stands for Voice over LTE, which is a digital packet technology that uses 4G LTE networks to route voice traffic and transmit data. It is a high-speed wireless communication standard for voice calls using mobile phones and data terminals. VoLTE allows voice calls to be transmitted over an LTE network instead of the older legacy voice networks, which provides higher quality calls, better service, and the ability to use voice and data simultaneously.

Here are some key points about VoLTE:

• VoLTE is based on the IP Multimedia Subsystem (IMS) architectural framework, with specific profiles for control and media planes of voice service.
• VoLTE has up to three times more voice and data capacity than older 3G UMTS and up to six times more than 2G GSM.
• VoLTE is important for network operators, vendors, original equipment manufacturers, and consumers.
• VoLTE is automatically active on most modern smartphones, both iPhones and Android devices.
• VoLTE lets you talk and use 4G LTE data simultaneously.
• VoLTE can improve the quality of your calls and allow you to use data for games, browsing, or scrolling while you talk on the phone at the same time.

To activate VoLTE, you need to check your phones settings. On Apple phones, you can go to Settings, click on Cellular, select Cellular Data Options, and then Voice & Data. If there is an option to Set VoLTE On, then turn it on. If you don’t see that option, it probably means that VoLTE is automatically enabled on your phone. On Android phones, you can go to Settings, select Connections or Network, and then select Voice Networks.
