Owning a modern smartphone from Xiaomi opens up access to a huge number of functions, but basic operations often raise questions for beginners. SIM-maps before adding a quick dial widget to the desktop. In this article, we will discuss all possible options for configuring phone numbers in the shell MIUI HyperOS so you can fully personalize your device.

Regardless of your model, whether it is a budget Redmi or flagship Xiaomi, the logic of the system remains similar, although the names of menu items may differ slightly. The correct configuration of contacts and SIM cards is the foundation of convenient use of the gadget. We will consider the technical nuances that will help to avoid confusion when calling and messaging.

Before you start to do complex manipulations, you need to make sure that the basic settings are correct. The shell interface may change, but the principles of operation remain the same. Let's take all the steps in order, starting from the beginning.

Physical installation SIM-maps and primary activation

The first step to “put a number” on the phone is to physically install the operator card in the device slot. Modern Xiaomi smartphones use a combined tray or separate slots for two nano-SIM. To extract the tray, you need to use a special clip included in the kit, or a thin needle, pressing into the hole at the end of the case.

It is important to be careful when installing the chip: the gold contacts should be directed downwards, and the bevelled corner of the card should match the shape of the tray. Once the device is turned on, the system automatically recognizes the new operator. If this does not happen, check whether the card is tightly sitting in the slot, since loose contact is a common cause of registration errors in the network.

💡

Use the original paperclip from the box to extract the tray so as not to damage the moisture sensor mechanism or the microphone located next to the SIM slot.

Once installed successfully, the phone will suggest setting up the network settings. Most of the time, you just need to choose the automatic configuration, but sometimes you need to manually enter the APN hotspot data. Without the correct settings, the Internet will not work, although voice calls may be available.

Setting priorities SIM-card MIUI HyperOS

If you have two SIM cards installed on your device, the system will suggest you set up rules for using them, which is a critical step, because it determines which number will make calls and send messages by default. → SIM-maps and mobile networks.

Here you'll see a list of installed cards, with the ability to assign roles, and you can choose one card for voice calls and another card for mobile Internet only, and this flexibility allows you to optimize costs by using different carrier rates for different tasks.

• 📞 Voice calls: select a specific SIM-Always Ask card or mode if you want to decide before every call.
• 🌐 Mobile Internet: Assign the card with the most traffic or the best speed in your area.
• 💬 SMS-Messages: Specify the main SIM for sending messages so as not to get confused in the dialogues.

Also available on this menu is the "Use 4G for Calls" or VoLTE feature, which allows you to have a conversation at the same time using high-speed Internet on the main SIM card. Without VoLTE enabled during a conversation, the phone can switch to 2G or 3G, interrupting the loading of pages.

How to pin the contact number on the main screen

Often, when users ask for a number, they mean creating a quick dial widget, especially for close family numbers, emergency services or work contacts that need to be called several times a day. Xiaomi's standard shell allows you to make a contact directly to your desktop.

To do this, you need to pinch the empty space on your desktop with your finger to make the edit menu appear. Select "Widgets" (or "Add"), find the Contacts or Phone app in the list. Select "Direct Call" or "Contact" among the available options.

⚠️ Note: When you add a direct call widget, the system will immediately ask you to select a contact from the address book. Make sure the number is written correctly, since after creating the widget, you can only change the associated number by removing the widget and creating it again.

You can resize the widget by stretching the boundaries if the launcher interface allows it, and that makes the quick access bar more informative, and you can put a photo of the contact in order to visualize the call button.

Creating Quick Dialing Labels and Contact Groups

An alternative to widgets is to use the Favorites feature in a standard call. To keep the number always at hand, open the Phone app, go to the Favorites tab and add the contacts you want to see, and they will be displayed at the top of the list every time you open the dial.

A more advanced way is to create contact groups, and you can group numbers into categories like "work," "family," "service," which makes it easier to navigate a phone book with hundreds of records on it, and it also allows you to send mass mailings quickly.

You can use a voice assistant to access even faster, and if you set up a call to mom or a call to taxi, you can put a number on the dial without touching the screen, which is convenient when your hands are busy or you're wearing gloves.

Table of comparison of methods of adding numbers

To make it easier for you to choose the right way to organize contacts, we have prepared a comparison table that will help you understand which method is best for your smartphone use goals.

As you can see from the table, widgets provide the fastest access, but they take up space on the screen. The favorites are the middle ground for most users. The choice depends on your personal preferences and habits of using the gadget.

Solving problems with number definition and display

Sometimes users are faced with a situation where the number is set, but the name of the caller is not displayed, or the incoming call is blocked. Often the problem lies in the permissions of the Phone or Contacts application. Check the settings in the Applications section → All Applications → Phone → Permissions.

Make sure the app has access to the phone book and SMS. Without this, the number detector will not work, and it is also worth checking the spam blocking settings built into MIUI, which can mistakenly mark important numbers as unwanted.

• 🔍 Duplicate Search: If one contact is displayed twice, use the Contacts Combination feature.
• 🛡️ Blocking: Check the blacklist for accidentally adding the right subscriber.
• 🔄 Sync: Make sure your contacts are synced with your Google account so you don’t lose them when you reset.

⚠️ Warning: If all contacts are missing after the system update, don't panic. You're probably in a mess. Go to Contacts, click three dots in the corner and select "Make Contacts," then check all sources (SIM, Phone, Google).

Use of third-party applications for contact management

Xiaomi’s standard tools are functional, but third-party developments from Google Play can offer more flexible settings. Apps like Truecaller or GetContact allow you not only to put numbers on quick dial, but also to determine unknown numbers by user base.

But privacy is important, because when you install these apps, you often give access to your phone book, and data security becomes a priority, and you use proven solutions and you read the license agreements carefully.

For complex photo and custom widgets, launcher apps or specialty contact widgets are great, and they can turn the desktop into a control panel with large buttons for the elderly or those with poor eyesight.

💡

The optimal strategy is to use standard MIUI widgets for speed, and third-party applications to connect only for extended number definition (Caller ID), carefully monitoring their resolutions.
