How to dial an additional number on Xiaomi smartphones: all ways

The number set on Xiaomi smartphones (including the Redmi and POCO lines) often raises questions among users, especially when you first contact customer service or corporate PBX. Unlike landlines, where the additional number is dialed after the beep, Android smartphones require special symbols or waiting functions. This article will help you understand all the nuances – from basic methods to advanced settings for different scenarios.

Complicating the problem is that the MIUI phone interface (the Xiaomi branded shell) has its own features, and some mobile operators impose additional restrictions. We will look at 4 working ways of dialing an additional number, including using pauses, the ";" symbol and manual dialing, and you will learn how to save the number with an additional in contacts so as not to enter it every time, and what to do if the system ignores your commands.

Important: The instructions are relevant for all modern Xiaomi models (2018-2026), including Xiaomi 13/14, Redmi Note 12/13, POCO F5/X5 and other Android 11-14 devices with MIUI 12-15 shell. If your phone runs on pure Android (for example, POCO F1 with custom firmware), some menu items may differ.

Basic method: dialing an additional number through pause

The most common method is to use a pause symbol (,), which automatically inserts a delay before dialing an extra number, which works on 90% of the PBX and does not require additional settings.

Instructions:

• 📞 Open the Phone app (the tube icon on the home screen).
• 🔢 Enter the primary subscriber number (e.g. 88001234567).
• ⏸️ Add a comma (,), then enter an additional number (for example, 123).
• 📞 Press the call button (green tube).

The system will automatically pause (usually 2-3 seconds) after connecting to the main number, then dial an extra one. If the pause is too short, you can add several commas in a row (or,, ), each increasing the delay by ~2 seconds.

⚠️ Note: Some operators (e.g. MTS or Beeline) block automatic dialing of additional numbers through a comma in roaming. In this case, use the manual dialing method (section 3).

Alternative method: semicolon symbol (;)

Instead of a comma, you can use a semicolon (;), which works like "waiting for a tone signal," which is useful if the PBX requires you to hear the beep first and then enter an extra number.

Example of set:

88001234567;123

The difference between, and;:

On some Xiaomi models (e.g. Redmi 9A), the; symbol may not work – in this case, try the p (pause) combination or type the extra one manually after connecting.

Manual input of the additional number after connection

If automatic methods do not work (for example, due to the characteristics of the PBX or operator), you can always dial an additional number manually:

1. Call the main number and wait for the connection.
2. After a welcome message or a beep, click the “Additional” button (usually appears on the call screen).
3. Enter the additional number on the keyboard and press # or * (if required by the PBX instructions).

On Xiaomi smartphones, the "Additional" button may not be available.

• 🔢 Dial the extra number right during the call - the numbers will appear on the screen.
• 📞 Press the green phone again to send the signal.

4. Saving the number with the additional in contacts

So you can keep the number in contact so you don't have to enter it every time.

1. Open the Contacts app.
2. Press + (add contact) or select an existing one.
3. In the number field, enter the primary number, then, or;, then an additional number (for example, 88001234567,123).
4. Keep in touch.

When you call from a saved contact, the system automatically dials an additional number.

• 🔄 Check that the contact settings do not include the tick “Only the main number».
• 📱 Update the Contacts app to the latest version on Google Play.

⚠️ Attention: On some firmware MIUI (for example POCO X3 Pro) The saved extra numbers may not work when calling via WhatsApp or Telegram, in which case use the standard Phone app».

5 Problems and Solutions: Why No Additional Number is Dialed

If the extra number does not pass, check the following points:

A critical feature for Xiaomi: on some models (for example, Redmi Note 10) pause symbols do not work when the “Saving traffic” mode is turned on in the settings SIM-Disable this option from the Settings menu → SIM-maps and mobile networks → Saving traffic.

💡

If you often call additional numbers, create a quick access widget on the home screen: add a contact shortcut to the saved additional number.

6. Advanced settings: tonal and impulse set

Older PBXs may require switching between tonal and pulse sets. By default, Xiaomi smartphones use tonal, but it can be changed:

1. Open Settings → System applications → Phone.
2. Select “Tonal Set” or “Pulse Set” (if available).
3. Save the changes and repeat the call.

If the option is not on the menu, it means that your Xiaomi model does not support pulse dial (relevant for devices after 2020).

• 📱 Use the outside. USB-pulsed-setting device (connected through OTG-adapter).
• 💻 Call from a landline or via IP-Telephony (e.g. Zadarma).

7. Features for corporate PBX and VoIP

When calling corporate PBX (for example, offices or banks) you may need to:

• 🔢 Dial * or # before the additional number (for example, 88001234567#123).
• 🎧 Wait for the voice menu and follow the instructions (e.g., “Type 1 for the sales team»).
• 📡 Use VoIP (e.g. via Skype or Zoom) if the mobile operator blocks additional.

For VoIP calls (via the Internet), the format of the add-on set may differ, for example, in Zoom or Microsoft Teams, the add-on is entered after the character; or through a separate field. Check the settings of a particular service.

💡

If you frequently call corporate PBX, save the number templates with different characters (,,,,, ) and test them alternately to find a working version.
