How to Set Up Voicemail on OPPO Muse R821

Voicemail — an answering machine in smartphones. It is free and enabled by default for modern devices. But the basic functions are not suitable for many people — it is important to set up voice mail correctly on OPPO Muse R821.

A vivid example — a person has two SIM cards of different operators installed in a smartphone. With basic settings, mail will work only on the first SIM card, ignoring the second one. And there are many similar cases of incorrect or incomplete work: a different number is specified, the wrong answer is selected, notifications do not come.

Setup in a standard application

Each smartphone manufacturer creates its own applications for making calls. But the instruction is suitable for 99% of devices — the software is standardized: the same buttons, names and paths are used.

To change the basic functions:

1. Go to in "Calls" (the icon in the form of a handset).

2. Check that the section is "Dialing" (Not "Contacts" and not "Favorites").
3. Click on the three dots in the upper right corner.
4. Click "Call Settings".
5. Swipe to the bottom and click "Voice mail".

There are two menus available here:

1. Service. By default, it will be "Your telecom operator". But you can contact third-party companies and set up mail through them.
2. Number. It changes at any moment, but it is better not to do this. The reason — past calls will be saved to the old address and will not be transferred to the new one. To change it:
1. Click on the "Voicemail number".
2. Enter any numbers you like.
3. Click "OK".
4. The change is successful — the message "The number has been changed" will appear.
5. The change has not been made — "The number has not been changed".

Setting up voicemail via "Phone" from Google

Many users abandon the standard application created by the smartphone manufacturer in favor of a "Phone" from Google — the developer of the Android OS. There are several reasons:

• works faster;
• works without extra "interlayers";
• optimized for Android as much as possible.

In the software, can change the voice mail, and there will be more opportunities:

1. Open the "Phone".
2. Click on the three dots in the upper right corner.
3. Go to in "Settings".
4. "Voice mail".
5. Two menus are used for management — "Extended Settings" and "Notifications".

In the first menu:

1. Enable notifications about incoming calls — turn on the toggle switch next to "Enable notifications".
2. Select the operating mode — "Default" and "Without sound".
3. The "Pop-up window" function will display an alert at the top of the screen.
4. In the "Sound" section, specify the sound played when the message appears.
5. The toggle switch opposite the "Vibration" enables or disables vibration.
6. The "Lock screen" allows you to select the mode of displaying alerts that are displayed without logging in.
7. "Notifications in the "Do not disturb" mode allows notifications to come even in the "Do not disturb" mode.

There are two items available in "Extended Settings":

1. Service. It is no different from the standard application.
2. The algorithm for changing the number is identical to the standard application.
