How to enable mobile HD calling

Volte is a high-definition voice call function. This function is currently only available on China Mobile among the three major domestic operators. The call cost is the same as an ordinary phone call, so activating this function is free. The priority of Volte's high-definition voice (video) call function is higher than that of WeChat and QQ using mobile networks for voice (video) calls.

Method/steps

1/3 step-by-step reading

< p>First of all, the mobile phone needs to support the VOLTE function. Check and turn on this function in the SIM card in settings (the location of different mobile phones is different, some mobile phones display this function as IMS, such as HTC M8F)

2/3

< p>Open the text message and send KTVOLTE to 10086. You will receive a text message in a minute or two indicating that the activation is successful. (Since I have already subscribed, the content of the text message I received is different) You can use this function by restarting your phone or flying. Generally, one of the Volte or IMS icons will be displayed on the top of the phone. Of course, this function cannot be used when the signal is poor (reflected in the absence of these two icons on the top of the phone)

3/3

In addition, if the phone supports Volte video calls, Video calls are also available for phone calls.
