Why can t the VOLTE function be opened?

Voice over LTE is an IP data transmission technology that does not require a 2G 3G network and all services are carried on a 4G network, which can unify data and voice services under the same network. In other words, the 4G network not only provides high-speed data services, but also provides high-quality audio calls, the latter of which requires VoLTE technology. If you need to handle related services, please contact your network operator.

Take the Apple 7 phone as an example.

Procedure. 1. At the beginning, the mobile phone card needs to be a 4G card, and the 4G ** is activated, and then you need to send SMS "KTVOLTE" to 10086 to activate this service before you can turn on the mobile phone VoLTE function normally.

2. Find the app "Settings" on the desktop of your phone and click to enter the new interface.

3. Then, after entering the settings operation interface, find the "Cellular Network" option and click to open.

4. After entering the cellular network operation interface, find the "Cellular Mobile Options" option and click to open.

5. Open "Cellular Options" and you can see that there is an option to "Enable 4G", click to open 6, turn on "Enable 4G", select the "Voice & Data" option, and the VoLTE function will be successfully turned on.
