How to untie the phone number from Mi Account on Xiaomi: 5 proven ways

Linking the phone number to the Mi Account is a prerequisite for the full use of Xiaomi, Redmi or smartphones POCO. It provides access to cloud services, data synchronization, and additional security features, but over time, users face the need to untie the old number — whether it's selling a device, changing a device. SIM-In this article, we will discuss all the current ways to delete a number from your account, including hidden nuances that are not described in the official documentation.

It's important to understand that the procedure is different from the standard deletion of an account, that untieing a number does not cause data loss, but it may require proof of identity. If you're selling a phone, we recommend that you untie the number first and then reset it to factory settings, otherwise the new owner will not be able to link his account.

Why you can’t just delete the number in your phone settings

Many users try to find the Delete Number option right in the Settings menu → Accounts → Mi Account, but they don’t have one, because Xiaomi deliberately complicates the process for two reasons:

• 🔒 Security: The linked number is an additional authentication factor, and deleting it without verification could make it easier to hack your account.
• 📱 Device Synchronization: The number is used to restore access to Mi Cloud, Mi Home, and other ecosystem features.
• 🛡️ Fraud protection: Without a linked number, it is impossible to verify identity when recovering a password or unlocking a device after resetting a device.

So the standard smartphone interface suggests that you only change the number, not delete it, and you have to use alternative methods to completely untie the number, which we'll talk about later.

Method 1: Untie the number through the official website of the Mi Account

The most reliable and versatile method is to use the web version of the Mi Account, which works independently of the phone model (suitable for Xiaomi 13T, Redmi Note 12, POCO F5, etc.) and the version of MIUI.

1. Open your browser on your computer or phone and go to account.xiaomi.com.
2. Sign in with your login and password. If two-factor authentication is enabled, confirm the login via SMS or email.
3. From the menu, select Profile → Account Management → Phone Number.
4. Click Delete the number (or Change if the deletion option is not available).
5. Confirm the action through SMS-code sent to the current number.

⚠️ Warning: If you sell a phone, delete the number before resetting to factory settings. After a hard reset, untie your account without access to the device will be extremely difficult.

Method 2: Using the Mi Account mobile application

If you don’t have access to your computer, you can use the official Mi Account app (not to be confused with your phone settings!) which is pre-installed on all Xiaomi devices, but may require an update:

• 📱 Open the Mi Account app (an icon with a man on an orange background).
• 🔄 Slip on the avatar in the top corner. → Account management.
• 📞 Select the phone number. → Delete.
• 🔐 Confirm the action through SMS email.

💡 If the Delete button is inactive, try temporarily disabling two-factor authentication in your account security settings.

Method 3: Uncoupling through Xiaomi Support

In rare cases (such as a phone number or email loss), the only way out is to call for support, which takes 1 to 5 days, but is guaranteed to work if you confirm ownership of the account.

Step-by-step:

1. Go to the support page: support.xiaomi.com.
2. Select the Mi Account section → Problems with entry.
3. Fill out the form by specifying: 🆔 Login (email or old phone number). 📝 Serial number of the device (can be found in Settings) → The phone. → General information). 📅 Date of account creation (approximately). 📄 Photo of a document confirming the identity (passport or driving license).

"Please untie the +7XXX phone number from Mi Account due to loss of account, I'm ready to confirm my identity."

⚠️ Note: If the account was created through a number and the email is not tied, the chances of recovery are minimal, in which case support may offer to create a new account and transfer data manually.

Method 4: Reset your account through Engineering Mode (for advanced)

This method is only suitable for devices with an unlocked bootloader and requires technical skills: it allows you to reset the number binding without access to the original SIM, but does not work on devices with MIUI 14 and later due to tightening security.

Instructions:

1. Install the Mi Unlock Tool (official) or MTK Engineering Mode (for MediaTek processor devices) on your phone.
2. Activate Developer Mode: Go to Settings → About Phone and tap the MIUI version 7 times.
3. Return to Settings → Additional → For developers and enable USB debugging.
4. Connect your phone to your PC and start the command: adb shell am start -n com.xiaomi.account/.ui.ResetPasswordActivity
5. In the menu that opens, select Reset the number anchor (the option may be called differently depending on the version of MIUI).

💡 Key takeaway: The most reliable way to unbundle through a web version of an account or support service, techniques like Engineering Mode are risky and only suitable for older models.
