How to dial a phone number on Xiaomi: the complete guide

Owners of Xiaomi, Redmi and Poco smartphones often face the need to do more than just call, but perform specific actions with a number, such as entering secret codes or setting up a recording format. The standard interface of the MIUI or HyperOS shell can hide some nuances that are not obvious to the beginner. Understanding how to type numbers and symbols correctly allows you to access the engineering menu or quickly contact rescue services.

In this article, we will look at all aspects of dialing on Xiaomi devices. We will look at standard methods, hidden keyboard capabilities, and ways to solve problems when a device refuses to connect a call. This guide covers both basic functions and advanced use cases.

Many users are unaware that simply clicking on screen buttons can have a continuation in the form of hidden functions. Dialing is the first step to managing your gadget’s network settings. Using characters and sequences correctly opens up access to diagnosis and fine-tuning communications.

Standard interface of dialing and its features

The main tool for calling is in the Phone app, which is pre-installed on all devices of the brand. The interface can vary depending on the region of the firmware: in global versions, the standard Google Dialer is used, and in Chinese or some Indian builds, MIUI Dialer is its own development. Despite the visual differences, the logic of the work remains the same for all models.

When you open the app, you see a digital keyboard where each button corresponds to a specific number or character. To make a call, you need to enter a sequence of numbers and press the green handset. However, if you plan to use special codes, you will need access to the asterisk and grille characters that are usually hidden on the second page of the keyboard or accessible through the character switch button.

⚠️ Note: In some security updates, Google is blocking execution USSD-codes containing pause or wait symbols if used to redirect calls without user confirmation.

It is important to note that clicking on a video call icon or message next to the number you enter changes the call type. If you have entered the number but the call button is inactive, check if the cursor in the field is worth entering additional characters that the system does not recognize as part of the phone number.

How to dial special symbols and pauses in the room

Often you need to dial an extra number with an office or bank number, where you need to enter numbers after the beep. Xiaomi has special pause and wait symbols. To activate them, hold your finger on the asterisk * or # button for 2-3 seconds until additional options appear on the screen.

There are two types of delays that can be inserted into the room:

• 📞 Pause (coma) - Automatic delay of 2 seconds before entering subsequent digits.
• ⏳ Waiting (comaint point): Waiting for an operator to respond before entering the numbers. The system waits until you press the send button.

When dialing with an extra number, for example, to access an answering machine, the correct format will look like this: the main number, then the pause symbol, then the additional number. In the dial bar, this is displayed as a comma. If you use the waiting symbol, the dialing of the additional number will only begin after you have confirmed on the screen.

These features are especially useful for automating frequently repeated calls to customer support or corporate services, and keeping that number in your contacts will save you the need to manually enter additional numbers after the beep.

Use of hidden codes and engineering menu

One of the main reasons users are looking for information on how to type numbers correctly on Xiaomi is access to hidden diagnostic features, which allows you to check the operation of speakers, vibrations, sensors and communication modules without installing third-party software. Special entrances are used for entry USSD-team.

The most popular diagnostic code is ##6484##. You need to enter it quickly, without pause, in the Phone app. The menu will open automatically, you don't need to press the call button. If the code doesn't work, your firmware version may be restricting access to this partition, or the carrier is blocking such requests.

Other useful codes for checking the status of the device:

• 🔍 *#06#: Instant conclusion IMEI and the serial number of the device on the screen.
• 📊 ##4636##: Test menu where you can see usage statistics and battery information.
• 📍 ##585##: Checking the work GPS-Module (not working on all models).

Be careful when changing the settings in the engineering menu. Inexperienced interference with the radio module settings or sensor calibration can lead to unstable network operation or loss of warranty. Changing the Preferred Network Type setting on LTE Only without the support of VoLTE by the operator can completely deprive you of the ability to make incoming calls.

International format and country code

When calling abroad or saving contacts for instant messengers, it is critical to use the correct number format. On Xiaomi smartphones, as on other Android devices, the standard is the international format, starting with a plus. The "+" symbol replaces the international line-out code (in Russia and Europe it is 8 or 00).

To gain a plus on the phone keyboard, it is usually enough to press and release the 0 (zero) button once or hold it, depending on the version of the keyboard. In the Google Phone Plus app, the phone appears automatically when you start typing, if the appropriate option is enabled in the settings. The correct entry of the number is: +7 999 000-00-00 for Russia.

Using an international format ensures that the contact is correctly identified on WhatsApp, Telegram and Viber. If you save the number in a local format (for example, starting with 8), messengers may not recognize the owner and you will not be able to contact him via the Internet.

Emergency call and call without SIM-map

In a critical situation, the smartphone should work even without the installed SIM-You can always have an emergency call button on the Xiaomi lock screen, and you can click on it, you can access a simplified keyboard, and you can dial universal rescue numbers 112 or 911.

112 is a single emergency number in Europe and operates in Russia and many CIS countries. SIM-card blocked PIN-If the phone does not see its operator's network, or if there is no balance in the account, the phone will try to connect to any available cell tower, even another operator.

However, there are limitations: if the device is in an area where there is no cellular signal at all (for example, in a deep forest or a basement with thick walls), an emergency call will not pass. IMSI-identifier (no SIM card), although by standard GSM It's got to work.

⚠️ Warning: Do not test 112 for a check unless there is a real need for it. False calls distract operators from real life rescue operations and can be tracked by law enforcement.

💡

Keep the contact "ICE" (In Case of Emergency) in your phone book with the ICE prefix. Rescuers know that in the case of a person who is unconscious, you need to look for this contact to contact relatives.

Problems with dialing and their solution

Sometimes users are faced with a situation where the call is immediately reset when dialing, or the keyboard does not respond to pressing, often the cause is an activated function "Block inbox" or "Black list", which can be mistakenly applied to outgoing in some scenarios, or a conflict of network settings.

If the call button is not pressed or the call is immediately discarded, follow the following steps:

• 📶 Check flight mode: Make sure it's off. Switch it back and forth to reboot the communications module.
• 📱 Network Selection: Go to Settings SIM-Select "Preferred Network Type" and try to switch temporarily to the 3G or 2G, Check if the voice communication is working.
• 🔄 Network reset: In Connections and Sharing, find a Wi-Fi, mobile and Bluetooth reset.This won't delete your personal data, but will return network settings to factory settings.

Another common problem is that the operator blocks dialing due to the ban on outgoing calls (for example, with a zero balance or a service lock), in which case a notification from the operator may appear on the screen.

💡

If standard reboot and network reset methods don’t help, the problem could be on the operator’s side or in a physical malfunction of the smartphone’s antenna module.
