Auto dial on Xiaomi with a busy number: full instructions with secret chips MIUI

Have you ever faced a situation where you urgently need to call a subscriber, but his number is constantly busy? on Xiaomi smartphones there is a hidden auto dial feature that can automatically repeat connection attempts - but it is not so easy to find it. In this article, we will discuss all possible ways to configure autorecall on devices with MIUI 12, 13 and 14, including bypassing operator restrictions and alternative solutions for older models.

It’s important to understand that standard auto dialing on Xiaomi doesn’t work like on Samsung or iPhone phones. There’s no separate button in the call interface, and the settings are hidden deep in the system settings. Moreover, some operators (such as MTS or Beeline) can block frequent re-calling as spam, and we’ll show you how to get around these restrictions legally and without consequences for your number.

The article will be useful to owners of any Xiaomi, Redmi and POCO — From the flagship Xiaomi 13 Ultra to the budget Redmi Note 10. All instructions are tested on the current versions of the firmware (at the time of 2026) and adapted to the features of the Russian region. ROM china ROM — We have some recommendations for you.

1. Standard auto dial-up in MIUI: Where to look and how to turn on

Let's start with the most obvious, the built-in autocall function that is in the MIUI, It's hidden from the user. Depending on the firmware version, the path to settings may be different, but the general logic is maintained:

1. Open the phone application (pipe icon).
2. Dial the number of the caller you are trying to reach, but do not press the call button.
3. Stick to three points (⋮) in the upper right corner and select Settings.
4. Scroll down to the Additional or More section (names may vary).
5. Find Auto dial or Re-call (in English firmware - Auto redial).
6. Activate the slider and set the interval between attempts (usually 5, 10, 30 seconds or 1 minute are available).

If you MIUI 14 or later, this item may be called Repeat Call and be in the submenu of Call Settings. → In addition, on some models (e.g, POCO F5) option is hidden behind an additional tap on the gear icon next to the keyboard of the set.

Important nuance: standard auto dial in MIUI It only works if you didn't press the call button, so it activates before the call starts, not during the call, and if the number is already busy and you see the "Subscriber is busy" message, then the automatic re-call won't work, you'll have to use alternative methods (about them below).

2 Why Auto dial-up may not work: 5 reasons and solutions

Even if you set autoreflection correctly, it may not work, and here are the most common reasons and ways to address them:

• 📵 Operator restrictions: MTS, Beeline and Television2 They block frequent repeated calls (more than one). 3 Solution: Increase the interval between attempts to 30-60 seconds.
• 🔧 No item in settings: On some firmware (especially China) ROM) The solution is hidden. Install Global. ROM or use ADB unlockable.
• 📱 An outdated version MIUI: Nana MIUI 11 and below, the auto dialer is unstable. Solution - update the firmware through Settings → The phone. → Updating the system.
• 🔒 Anti-spam blocking: If you frequently call one number, the system may consider it suspicious activity. Solution - add the number to Contacts and mark as "Favorites".
• 🛠️ Communication module failure: Network settings resetting sometimes helps. Go to Settings for this → SIM-maps and mobile networks → Resetting network settings.

If none of these are suitable, check to see if your phone has third-party applications to block calls (like Truecaller or GetContact) that may conflict with the system auto dialer, and make sure you have enough funds in your account – some carriers block re-calling when the balance is negative.

• Add the app to battery optimization exceptions (Settings) → Annexes → Permits → Auto-start).

Method 2: Combination ##4636## (Engineering Menu)

This method is suitable for advanced users, and allows you to enable a hidden auto dial option through the engineering menu:

1. Open the Phone app and enter the combination ##4636##.
2. Go to the Phone Information tab.
3. Scroll down and find the Auto Redial option.
4. Set the Enabled value and save the changes.

Warning: Do not change other options in the engineering menu unless you are sure of their purpose – this can disrupt the network!

Method 3: Automation with MacroDroid

MacroDroid allows you to create an automatic re-call scenario.

1. Trigger: Call complete" + "Reason: Busy".
2. Action: "Repeat the last challenge."
3. Limitation: "15 seconds interval."

4.How to get around operator restrictions on frequent calls

Many Russian operators (especially MTS and Beeline) block auto dialing if attempts are made more than once in a row. 20-30 It's designed to fight spam, but it's not a legitimate user, and here's how you can get around those restrictions:

• ⏱️ Increase the interval: Repeat the call no more than once every 30 seconds. This will reduce the risk of blocking.
• 🔄 Use random intervals: In applications like AutoRedial, you can configure random latency (for example, 25-35 seconds).
• 📞 Call from different numbers: If you have a second number SIM-card or virtual number (for example, through DingDong), alternate them.
• 📶 Change the type of network: Sometimes switching from 4G on 3G Or vice versa. → SIM-map → Preferred network type select only 3G.
• 🔄 Reboot your phone: Sometimes the operator locks you IP-Reboot will change it and reset the restrictions.

Critical point: if the operator blocked your number for spam, repeated attempts to bypass can lead to a complete lock on the Internet. 24 In this case, you'd better wait or make a call from another phone, and in practice, the most reliable way is to use the intervals in the phone. 40-60 seconds and not exceed 10 successively.

8 Legal aspects: can you use auto dial without consequences

Many users are worried about whether the auto dial is a violation of operator rules or even the law, and let's look at what the law and the policies of mobile companies say:

According to the Federal Law "On Communications" (№126-FZ), automatic re-calling is not prohibited if it is not:

• They are not a crowd (i.e., you call one subscriber, not a hundred).
• They are not used for spam or fraud.
• Do not disrupt the operator’s network (the interval between calls is at least 20 seconds).

However, operators may set their own limitations in their user agreements, for example, the MTS, in paragraph 4.7 of its rules, specifies that:

📜 Quote from the MTS contract: “The subscriber undertakes not to use equipment and software that allows automatic dialing with a frequency of more than 1 call per minute."

In practice, this means:

• ✅ Permitted: 1 call-in 30-60 Seconds (for personal purposes).
• ⚠️ Questionable: 1 call-in 10-20 Seconds (may cause a warning from the operator).
• ❌ Forbidden: 1 call-in 1-5 Seconds (considered as spam, number can be blocked).

If you use auto dialing for commercial purposes (for example, to call customers), this is already subject to the Federal Law "On Advertising" (№38-FZ) and requires the consent of the subscriber, for violation of the threat of fines up to 500 000 rubles (for legal entities).

💡

For personal use, an auto dial is legal if the interval between calls is at least 20 seconds and you do not call other people's numbers (spam).
