Why can't I turn off the volte function after I send _Dvolte to 100 10?

Unicom users can turn off the VoLTE function in the following ways:

1, short message: After TDVOLTE is sent to 100 10, reply "Y" to close;

2. China Unicom APP: Select "Service >"; Processing > VoLTE HD call ";

3. online business hall: click "handle > VoLTE HD call";

4. Close the business hall through the local Unicom customer service hotline or with the owner ID.

Tips: As the rules of different provinces are slightly different, please take the local as the standard.
