Automatic re-dialing, known as auto dialing, is one of the most sought-after features in the modern smartphone arsenal, especially when it is urgent to contact a subscriber whose line is occupied. Owners of the popular Xiaomi Redmi Note 8 Pro model often look for a way to activate this tool so as not to waste time on constant manual attempts to connect. In the MIUI operating system, which is based on Android, the implementation of this feature may be slightly different from the stock version, which raises questions among users accustomed to other interfaces.
In this article, we will discuss in detail all available methods for activating auto dial on your device, including standard system settings and using third-party applications. You will learn how to correctly adjust the intervals between calls and what hidden features the engineering menu offers for advanced users. Understanding these nuances will allow you to effectively manage calls and not miss an important conversation even in conditions of poor communication or high network congestion.
It is worth noting that the term "auto-dialer" can be interpreted differently depending on the context: it can be a simple repetition of the last dialed number or a more complex system for automatically forwarding incoming calls to another number. We will consider both options, paying special attention to the specifics of the Redmi Note 8 Pro with the MediaTek Helio G90T processor, which can affect the speed of processing network requests.
Standard Re-Calling Settings in MIUI
The first and most obvious way to activate the re-typing feature is to use the built-in MIUI shell capabilities. On the Xiaomi Redmi Note 8 Pro, this functionality is often hidden in the depths of the call settings menu, which can confuse the inexperienced user. First, you need to open the standard Phone application, which usually has a green icon with a phone handset, and go to the menu of additional options.
In the list that opens, select Settings, and then find the section responsible for additional functions or call parameters. This is where the switch that activates automatic re-typing is located. Once this option is enabled, the system will automatically initiate a new call after a certain period of time if the previous attempt was unsuccessful due to line employment.
⚠️ Warning: Activating the auto dial function can cause a quick battery discharge if the line is occupied for a long time, so watch the battery level.
It is important to understand that a standard implementation of this feature in MIUI may have restrictions on the number of repeated attempts or the length of the waiting interval. Some versions of the firmware allow you to adjust these settings more flexibly, while others offer only a binary option "on / off." Check the relevance of your version of MIUI in the "About Phone" section, as new updates often optimize the algorithms of telephony.
Access to advanced settings sometimes requires activating developer mode or using special codes, which we will talk about in the next sections. However, for most users, standard settings are enough to ensure continuity of communication. If you do not find the right switch in the described place, it is possible that your carrier blocks this function at the network level, and then you will need to use alter methods.
Use of Engineering Menu Codes to Activate Functions
A more advanced method of setting communication parameters on Xiaomi Redmi Note 8 Pro is the use of engineering menus available through special USSD-This interface provides access to hidden modem settings and network settings that are not displayed in the regular menu. Be careful when working with these settings, as incorrect change of parameters can lead to unstable operation of the device.
The code ##4636## is often used to enter the engineering menu, which should open the diagnostic menu. In some cases, depending on the regional version of the firmware, the code may differ or be blocked by the manufacturer. In the menu that opens, you should find the "Phone Information" or similar section, where you can find settings related to the behavior of the modem when you fail to call.
- 📱 Find the "Set preferred network type" to select the type of network that may affect the connection speed.
- 🔄 Look for options related to Call Retry or Auto Redial in advanced settings.
- ⚙️ Check status. SIM-maps and make sure it is correctly defined by the system.
- 📡 Make sure you choose the right type of network (LTE/3G/2G) for your operator.
There are a lot of abbreviations and parameters inside the engineering menu. It's not recommended to change values that you're not 100% sure about. Our goal is to find parameters that are responsible for repeated call attempts. If the standard code doesn't work, there are alternative ways to log in through the Engineering Mode app, which you can find in the application directory or install separately.
⚠️ Warning: Changing the settings in the engineering menu can result in a loss of warranty or disruption of the radio module, so write down the initial values before making changes.
Using an engineering menu gives the user maximum control over the phone's performance, but requires a high degree of caution. On the Redmi Note 8 Pro with its powerful MediaTek processor, some settings can be hidden deeper than on Qualcomm-powered devices. If you're unsure of your actions, it's better to use safer customization methods through the standard menu or third-party apps.

Alternative applications for automatic dialing
If the built-in capabilities of the Xiaomi Redmi Note 8 Pro do not meet your requirements for auto dial functionality, a great solution is to install specialized applications from the Google Play store. There are many programs developed by third-party developers that offer advanced call management capabilities, including flexible setup of re-dial intervals and lists of numbers for calling.
One popular solution is Auto Redial, which allows you to adjust the number of attempts and the waiting time between them to within seconds, and these applications often run on top of a standard call, intercepting dial commands and executing them according to a given algorithm, which is especially useful for those who often encounter busy lines during working hours.
When choosing an app, pay attention to the permissions you request. The auto dial feature requires access to your phone and contacts, but requests for geolocation or camera access should alert you. Choose trusted apps that rank highly and have a lot of positive feedback from Android users.
- 📞 Auto Redial is a simple and effective application with a minimalist interface.
- 🔄 Redial Pro – offers the creation of lists of numbers for sequential calls.
- ⏱️ Call Scheduler – allows you to schedule calls and set up repeated attempts on a schedule.
- 📱 Truecaller – in addition to determining the number, has basic functions of re-calling.
Using third-party apps can slightly increase the load on the device’s RAM, but on the Redmi Note 8 Pro with its 6 or 8 GB of RAM, this will have little to no effect on performance. The main thing is to set an exception for such an application in the battery settings so that the MIUI system does not “kill” its process in the background, interrupting the auto dial cycle.
💡
For stable auto dialing applications on MIUI, go to Settings -> Battery and Performance -> Application Management, find your application and select "No Limits".
Configuring call forwarding as an alternative
In some cases, auto dialing means that users can redirect an incoming call to another number if you can’t answer. On the Xiaomi Redmi Note 8 Pro, this feature is easiest to configure via the call settings menu or using the call settings menu. USSD-Redirection can be useful if you want the call to go to another phone while you are busy or out of range.
To set up the redirect, go to the Phone app, click three dots in the corner of the screen and select Settings. Next, look for Accounts for Calls or Additional Settings, where forwarding options will be available. You can set up the redirect whenever you are busy, when you are not responding, or when the phone is off.
There are standard codes for managing redirects that most operators use, such as **21*phone number# activates unconditional forwarding, and the ##21# deactivates it, and these codes allow you to quickly change settings without going deep into the smartphone menu.
| Type of forwarding | Description | Activation code (example) |
|---|---|---|
| Always. | All calls are translated immediately. | **21*number# |
| If it's busy. | Translation when the conversation is going on | **67*number# |
| No answer. | Translation after the horns | **61*number# |
| Unavailable. | Translation with the phone off | **62* number # |
On the Redmi Note 8 Pro, the redirect configuration interface is fully integrated into the system, making this process convenient and intuitive even for beginners.

Troubleshooting and troubleshooting
Despite the reliability of the Xiaomi Redmi Note 8 Pro, users may encounter situations where the auto dial function is not working properly or at all. One common reason is the aggressive MIUI energy saving policy, which can block the background processes of the Phone application. To fix this, you need to manually adjust the permissions and battery settings for the corresponding applications.
Problems can also arise from SIM-If the card is old or has damaged contacts, modem may not process network signals correctly, causing re-typing to crash. SIM-If the problem persists, check the card on another phone or replace it with a carrier.
⚠️ Note: If the auto dial doesn’t work after all the settings, reset your network settings, but remember that this will delete your stored Wi-Fi passwords and Bluetooth settings.
In some cases, the problem may be that you have installed call blocking apps or number detectors, try temporarily disabling them and check the auto dialer, if the function is working, then the problem was software compatibility, and updating all applications to the latest versions can also solve the problem.
If nothing works, consider resetting your phone to factory settings. Make sure to back up all the important data before doing so. On the Redmi Note 8 Pro, this process takes about 10-15 minutes and brings the device back out of the box, eliminating software errors accumulated over time.
💡
Resetting network settings often solves problems with auto dialing, if the reason lies in a software conflict or modem error.
