When a line is busy at the most inopportune moment, it is familiar to every smartphone owner, especially for Xiaomi Redmi 10 Pro users, who often use the device for business negotiations or communication with government services. Constantly pressing the call button is not only tiring, but also distracting from other tasks, reducing productivity during the day.
Fortunately, the Android operating system that powers the MIUI shell offers flexible tools to automate the process. Enabling auto dial-up allows the device to self-repeat connection attempts at predetermined intervals, freeing up hands and nerves, making the smartphone a truly smart assistant.
In this guide, we will discuss in detail all the available ways to implement this feature on the Redmi 10 Pro model. You will learn about the regular capabilities of the phone, hidden engineering menus and proven third-party solutions that guarantee connection even during peak hours on the operator’s network.
The standard features of the Android system on Redmi 10 Pro
Many users mistakenly believe that the standard MIUI Dialer call lacks automatic re-typing. However, starting with certain firmware versions, the Google Phone algorithms and the proprietary MIUI app incorporate a basic retrai mechanism that activates automatically when a "busy" or "unavailable" signal is received.
To activate, you need to go to the settings of the Phone application. Usually the path is: Settings → Call settings → Auto Repeat. Here the system will suggest selecting a repeat interval. It is important to understand that the regular functionality is often limited by the number of attempts or latency, so as not to create unnecessary load on the network.
⚠️ Note: Some global firmware versions for Redmi 10 Pro may have autorepeat points hidden by the carrier, and if you don't find this option, your service provider is blocking the protocol at the software level.
If standard settings don’t meet your needs, such as a more aggressive repeat call algorithm, it’s worth considering alternative methods.The standard interface is often focused on minimalism, hiding advanced features.

Use of the engineering menu codes and USSD-request
One of the most effective but little-known ways to customize network behavior is by using special codes. Xiaomi's Engineering Menu provides access to deep radio settings. The ##4636## combination is commonly used to enter the test menu.
Once you're in the test menu, select "Phone Information" where you can find the network type you prefer, which indirectly affects the reconnection rate. USSD-codes provided by the operator itself that emulate the "Autoresponder" or "Director" function".
Below is a table with the most common codes that can work on the Redmi 10 Pro depending on the SIM card:
| Operator/Type | Activation code. | Description of action |
|---|---|---|
| Universal (GSM) | *68* number # | Redirection when busy (requires settings) |
| Engineering menu | ##4636## | Radio and network testing |
| Resetting of diversions | ##002# | Cancel all redirects |
| Call status | #43# | Checking the status of waiting for a call |
Be careful when entering codes starting with ##, as they can reset important redirect settings without additional confirmation. Always check the status of services before making changes to the network configuration.
Third-party applications for call automation
When Xiaomi’s built-in tools aren’t enough, specialized apps from the Google Play Store come to the rescue, running on top of a standard call, intercepting the call’s end signal and initiating a new set after a given period of time.
The most popular and secure solutions for Redmi 10 Pro are Auto Redial and Automatic Call Redial, which allow you to flexibly adjust the number of attempts, the interval between them (for example, every 5 seconds) and activation conditions (only when the signal is busy or always).
Installing this software requires special permissions, you'll need access to call and contact management, and without that, the app won't be able to technically re-dial.
☑️ Checking before installing the application
It is important to choose high-rated and high-settling apps to avoid malicious code. Some left-wing programs may use your phone to make paid calls to premium numbers without your knowledge.
Setting up scripts through Mi Automation
Owners of the Redmi 10 Pro have the unique advantage of a built-in MIUI Automation (or Mi Automation) automation system, which allows you to create complex scenarios of smartphone behavior without installing additional software.
To create an auto dial script, go to Settings → Additional settings → Task Automation. Create a new scenario where the condition ("If") is to complete a call with a certain status, and the action ("To") is to re-dial the last number. However, standard MIUI automation functionality is often limited to telephony due to Google security concerns.
⚠️ Attention: Automation scenarios associated with telephony may not work if the Phone application does not have the appropriate power saving privileges.
If standard automation fails, you can use more advanced tools like Tasker or MacroDroid, which work great on the Snapdragon or MediaTek processor installed in your model, and they allow you to implement logic of any complexity, including voice-responder analysis.

Optimizing the operation of the radio module for fast connection
The speed of connection depends not only on the software, but also on the settings of the radio module. On the Xiaomi Redmi 10 Pro, you can force the network mode that provides the most stable connection in your area.
Go to Settings. → SIM-maps and mobile networks → The preferred type of network. If you're in an unsuspecting reception zone, switch from 5G/4G on 3G or 2G can paradoxically speed up the dial-up process, as these networks are often less congested and have better penetration in buildings.
It’s also worth checking whether Flight mode is enabled in background tasks or background activity limitations for the Phone app. MIUI is known for aggressive memory optimization, which can kill the re-typing process.
- 📶 Signal Check: Make sure the signal level is not lower 2-3 division before launching a series of calls.
- 🔋 Power Saving: Turn off Ultra Battery Saver during important negotiations.
- 📱 Cache Clearing: Periodically clear the cache of the Phone application through Settings → Annexes → Application management.
Regularly restarting the device also helps to reset temporary registration errors in the network of the mobile operator, which is especially important for users who do not turn off the smartphone for weeks.
💡
Optimizing network settings and turning off aggressive power saving for the Phone application can increase connection speeds by 20-30% without installing additional software.
