• 📱 Phone models – on flagships (for example, Xiaomi 13) the option can be expanded, and on budget Redmi – cut down.
• 📶 Operator – some providers (for example, MTS or Beeline) block frequent repeated calls, considering them spam.
• 🔄 Versions MIUI — in old firmware (up to) MIUI 12) the auto dial could work differently than in new.

The main scenarios where the function is irreplaceable:

• 🚨 Emergency situations – when you need to contact a person urgently (for example, if they are in danger or have forgotten an important thing).
• 📞 Business calls – if the caller is often in meetings and can not pick up the phone the first time.
• 👨‍👩‍👧‍👦 Communication with relatives – elderly people sometimes do not hear the first call, but pick up the phone afterward 2-3 repetition.

Before installing, check the permissions of the application – it should only ask for:

• 📞 Access to calls (to initiate a call).
• 📱 Working in the background (to avoid closing).

If the application requires access to contacts, SMS or geolocation, it is suspicious and may indicate spyware.

Why Autocall is not working: 5 reasons and solutions

Even if you set up the auto dialer correctly, it may not work. Let's look at the typical problems and how to fix them:

1. The operator blocks frequent MTS calls, Beeline and MegaFon limit the number of repeat calls per minute to combat spam. If you call the same operator's number, the restrictions are tighter. Solution: Increase the interval between repeats to 60-90 seconds.
2. If a subscriber has added you to the block list, the auto dialer will endlessly try to reach you, but the call will always be reset. Solution: Try calling from another number or write to the phone. SMS.
3. Failure to work SIM-card SIM-The card is unstable (for example, due to poor contact), the auto dial may be interrupted.Solution: Reboot the phone or reinstall SIM-map.
4. Energy Saving Blocks Background Operation In Power Saving or Super Energy Saving mode, MIUI suspends background processes, including auto dialing. Solution: Add the Phone app to exceptions: Settings → Battery → Battery Optimization → All apps → Phone → No restrictions.
5. Conflict with other Call Blocking Applications (such as Truecaller) or antiviruses may interfere with AutoDialing Solution: Temporarily disable third-party applications related to calls.

How to circumvent operator restrictions on auto dial

Mobile operators are actively fighting against auto dialing, considering it a tool of spammers. If your repeated calls are blocked, try these methods:

• 🔄 Instead of a fixed pause (for example, 30 seconds), set random intervals: 25, 40, 55 seconds.
• 📱 Call from another device if you have a second phone or tablet with SIM-If you use a map, try setting up an auto dial on it, the operators lock it by number, not by device.
• 🌍 Use VoIP Services like WhatsApp, Telegram or Skype have no restrictions on repeat calls.
• 📞 Some operators (e.g. Tele2) offer a callback service. If the subscriber does not answer, the system invites him to call you back.

⚠️ Note: Bypassing the operator’s restrictions may be considered a violation of the user agreement. If you use an auto dial for business purposes (such as a call center), check with your provider to avoid blocking the number.

Hidden chips of auto dial on Xiaomi: little-known opportunities

• 🔕 If the caller finally picks up the phone but the call is interrupted, the auto dial won't resume automatically. To continue repeating calls, you need to manually restart the function.
• 📵 If you activate the auto dialer and then you turn on the flight mode, the function will not reset. Once you turn off the flight mode, the re-calls will continue to work with the same settings.
• 🔄 If the phone resets (for example, due to an update), the auto dial counter will reset, which means that once the call device is turned on, as much as the settings indicate, rather than dial-up before answering, will be done".
• 📱 Dual support SIM On smartphones with two SIM-The auto dialer only works on the line from which the first call was made. SIM not.

Another life hack: if you want the auto dialer to run indefinitely (until you manually turn it off), set the number of attempts to a maximum of 10 and a minimum interval of 5 seconds.

• 📵 Blocking your number by the operator.
• 🔋 Quick battery discharge.
• 📱 Overheating of the phone (due to constant operation of the communication module).
