How to ban incoming calls on Xiaomi: a complete guide to blocking

The modern smartphone, especially Xiaomi devices, has become the center of our digital lives, but sometimes the need to remain quiet becomes critical. Users often look for ways to ban incoming calls on Xiaomi to avoid intrusive advertising, calls from collectors or simply disconnect from the fuss during an important meeting. Owners of devices with a shell MIUI or the new HyperOS have in their arsenal a lot of tools that allow you to flexibly manage the availability of your room.

In this article, we will take a look at all the existing methods, from standard system settings to operator codes, you will learn how to configure "Do Not Disturb" mode so that you miss calls only from selected contacts, or how to completely redirect calls to voicemail. A deep understanding of these features will allow you to turn your smartphone into an effective tool that works by your rules, rather than dictates conditions.

It’s worth noting that locking methods can vary depending on the firmware version and the region for which the device is released. However, the basic principles of telephony in Android remain unchanged, making our instructions relevant for most models, from the budget Redmi to the flagship Xiaomi 14.

Use of the "Do Not Disturb" mode

The most civilized way to temporarily shield yourself from calls is to use the Do Not Disturb system function. Unlike full lock, this mode allows you to flexibly configure exceptions, skipping calls from loved ones or repeated calls. To activate, open the notification curtain and click on the crescent icon or go to Settings → Sound and Vibration → Do Not Disturb.

Inside the settings menu, you can configure the filtering rules in detail, for example, you can only allow calls from your favorites list or from contacts marked as Work, which is ideal for situations when you are in a meeting or in a movie, but waiting for an important call from a particular person.

⚠️ Warning: Make sure the Do Not Disturb settings do not activate the option to skip repeat calls if you want to block everyone. Often persistent callers can break through the filter if they call a second time within 3 minutes.

It also allows you to set the schedule to automatically turn on this mode, so you can set a time frame, like 23:00 to 7:00, so that you don't interrupt your night's sleep, which is much more convenient than manually turning on air mode or dropping calls every night.

Completely blocking all incoming calls

If your goal is to completely ban incoming calls to Xiaomi for a certain period, the regular phone tools offer the "Block inbound" feature, which you can find in the "Phone" app (green handset), click on the three dots in the upper right corner or go to the call settings to find "Block inbound".

Activating this feature will redirect all calls directly to voicemail or give a “busy” signal depending on your operator’s settings. It is important to understand that in this case, the caller will hear a beep or message, but you will not receive any notification, even if the phone is in front of you with the screen on.

Some versions of the MIUI shell allow you to set a password to change these settings, which will prevent children from accidentally unlocking or accidentally tapping, which is especially useful in a corporate environment or when using service phones.

Remember that when the full lock is included SMS-The messages may keep coming in because they're different channels, and if you want complete isolation, you'll have to combine this with blocking notifications from messengers.

Configure forwarding through codes and menus

One of the most reliable ways to prevent incoming calls on Xiaomi, especially when the phone is off or out of range of the network, is to set up forwarding at the operator level. USSD-code.

To configure through the smartphone interface, go to the Phone app, open the settings and select Accounts for Calls (or Settings). SIM-There you will find the section "Redirects"; the system will offer several options: forwarding when busy, if there is no response or always.

Alternative and faster method: using USSD-They work on any phone, regardless of the version of Android. Here are the basic codes you might need:

• 📞 **21*number# – activation of unconditional forwarding of all calls to the specified number.
• 🔒 ##21# – Cancel all types of redirects (return to factory settings).
• 📵 **67*number# – forwarding only if your number is occupied.
• ⏳ **61*number# – forwarding if you haven’t picked up the phone for a certain time.

Once you have entered the command, the operator will confirm the call, and even if your Xiaomi is dead or off, the call will go to another number.

Blacklisting and blocking by keywords

Often users need to stop calling from specific categories of subscribers, such as spammers or intrusive delivery services, and Xiaomi has built a powerful tool called Antispam, which is based on Mi Cloud database and local listings.

To add a number to the blacklist manually, open the call log, click on the number and select "Block." A more advanced method is to use the lock menu. Go to Settings. → Annexes → Application settings → Antispam (the path may differ depending on the version) MIUI). You can enable the blocking of unknown numbers, hidden numbers or numbers from other regions.

Keyword blocking feature is particularly useful for filtering SMS-Spam, which often precedes phone calls, you can ask the words "credit", "winning", "promotion", and messages with such content will not bother you.

Updating spammer databases automatically, if allowed in the settings, allows you to proactively protect yourself from new schemes of scammers who change numbers every day.

Hiding your number (Anti-AON)

Sometimes, the phrase “no calls” means that users want to hide their number when a call is made so that the person can’t call you back or see who is calling you, which is called “Number Definer” or CLI in Xiaomi’s settings.

To change the settings go to Settings → SIM-maps and mobile networks → Choose. SIM-map → Additional settings → Number detector. There are three options available here: "Show number", "Hide number" and "Default (like on the network)". Select "Hide number", and when making calls your contacts will see "Unknown number" or "Hidden number".

It is important to note that this feature depends on support from your carrier, some providers block the possibility of hiding the number on the tariff plans or require the connection of a paid service "AntiAON".

⚠️ WARNING: If you hide your number, many people may simply not answer the phone as the number will be marked as spam or unknown.

There is also a temporary way to hide the number for a single call: Before dialing a number, dial a special code (often #31# before the subscriber number), after which the call will pass with a hidden ID.

Problem Solving: If the settings are not saved

Xiaomi users sometimes face a situation where lock settings are reset or not applied, which may be due to the aggressive MIUI energy saving system, which kills the background processes responsible for filtering calls.

To fix this, look for the Security or Antispam app in the installed app list. Go to Settings → Apps → All Apps → Security. You want to allow autorun and remove restrictions on running in the background. Make sure there is a "No Restrictions" check in the Activity Control section.

Another reason could be a conflict with third-party calling apps like Google Phone or Truecaller. If you use a non-staff call, lock settings may be in its own menu, not in Xiaomi's system settings.

If you change your phone book or reset your settings, remember to re-activate the lock function. After the hard reset, all settings return to factory values.
