1. Enter the string * # * # 86583 # * # * in the field for dialing numbers, a message will appear after the last character, which must end with DISABLE. If ENABLE, we repeat the string again. This will allow VoLTE because this menu is hidden by default.

2. Enter the string * # * # 869434 # * # * as above, again the message with DISABLE must appear at the end. We have enabled VoWIFI.

3. Using the SIM card settings, we adjust the SIM card number in the international format, ie + 4xx .... I don't know if it's necessary, but some sources state it, so I listened and set it up. Activate VoLTE and VoWIFI

3. Install the Shortcut Maker software through the Play Store.

Find the name MODEM

If you do not find the MODEM name, search for Rueban(MTB)

4. Restart the phone and both functions should be active. We test VoWIFI by selecting the mode on the plane and then turning on WiFi and trying to call someone. If we succeed, we have won.

After successful activation, you can use Shortcut Maker to uninstall.
