Xiaomi’s current smartphones, which are powered by MIUI or HyperOS shells, store a huge amount of personal information, and a key element of privacy is the phone number. Users often wonder how to delete a number in Xiaomi, meaning that it’s a completely different scenario: from the banal cleaning of the contact list to completely resetting the device to the account before selling. Understanding the difference between these actions is critical, since improper manipulation can lead to loss of access to important services or inability to make calls.
In some situations, owners want to hide their ID when outgoing calls so that the person sees the status of "Unknown" or "Hidden", in other cases it is a physical extraction. SIM-By removing a number from the operator's settings if it's dynamically assigned, data privacy is becoming the number one priority in the digital age, and managing those settings properly protects you from spam and unwanted attention.
This guide covers all aspects of working with a phone number on Redmi and POCO devices. We will consider methods of hiding Caller ID, how to delete records from the phone book, the procedure for completely resetting the settings for detaching the number from Mi Account, as well as the technical nuances associated with IMEI. It is important to clearly understand the purpose of your actions so as not to disrupt the operation of the device.
Hiding the number in outgoing calls
The most common request is how to make sure that your number is not displayed at the interlocutor during the call. In Xiaomi smartphones, this feature is governed by the network settings and may depend on the tariff of your mobile operator. To activate the incognito mode, you need to go to the standard Phone application and open the call settings.
The interface may vary slightly depending on the version of Android, but the logic remains the same. You need to find the item responsible for additional settings or identification of Caller ID. Here the system will offer several options: show the number, hide it or use the default settings set by the carrier.
- 📞 Open the Phone app and click on three dots in the corner of the screen.
- 📞 Go to the "Settings" section» → «Accounts for calls" or "Additional settings».
- 📞 Choose yours. SIM-card, if two are installed.
- 📞 Find a point «ID Subscriber and select the option “Hide the number».
⚠️ Note: If the carrier does not support network level number hiding, the phone may give an error when trying to change this setting, in which case you will need to connect a paid service from your provider.
It’s worth noting that emergency services and some organizations can still see your ID, regardless of the privacy settings you set. Also remember that when you hide a number, you may not receive an incoming call from someone who has an anonymous call blocked, a two-way process that requires a conscious approach to communication.
Removing contact numbers and call history
If by number deletion you mean cleaning a phone book or call log, MIUI provides convenient tools for mass recording management, and users often forget that the number can be stored not only in the memory of the phone, but also synced with Google Contacts or Mi Cloud.
You have to work sequentially to clean up. First, check the device's local memory, then go to the cloud. Deleting a record from one place doesn't always guarantee it disappears from another place if synchronization is enabled, so it's important to check all the data sources.
The process of deleting from the call history is even easier: just press the desired number in the list of recent calls and select the appropriate basket icon. However, to completely clean the log, you will have to use the “Clear Call History” feature, which is available in the settings menu of the Phone application.
☑️ Verification of contact sources
Xiaomi’s system often automatically combines contacts, but sometimes one person can be recorded multiple times with different numbers. Use the “Joint Duplicates” feature in the contact settings to get the database in order before removing unnecessary entries.
Change and delete the number in the settings SIM-map
In the Android operating system there is a field where the phone number assigned to the phone number is stored. SIM-Often, you write down a number you had before, or the field is left blank, and changing that information doesn't affect how the communication actually works, but it can be displayed in some applications and device settings.
To change or delete this number in the system settings, you will need access to the control menu. SIM-Note that this is purely cosmetic for the smartphone itself and does not change your operator number. SIM telecommunications operator database.
To edit, go to Settings, select About Phone, then Status or All Settings. In some versions of the firmware, the path may look like Settings → SIM cards and mobile networks → SIM settings.
| Parameter | Description | Impact on communication |
|---|---|---|
| Phone number | Text field in the phone memory | No influence. |
| ICCID | Unique identifier SIM-map | Card identification |
| IMEI | Identifier of the device itself | Registration on the network |
| Type of network | 4G/5G/LTE parameters | Signal quality |
⚠️ Warning: Don’t try to change the fields IMEI or ICCID This can result in the device being locked by the operator or the loss of warranty. edit only the Phone Number field if available.
If you've changed SIM-You can often type in a new number in this field, but modern Xiaomi smartphones often automatically read the number from the chip if the operator transmits this information (MSISDN). If the field is gray and not available for editing, then the data is taken directly from the SIM card.
Unbinding the number from the Mi Account before the sale
The most important step if you plan to sell or give away your Redmi or POCO smartphone is to untie the device from your account, so as long as the phone is tied to your Mi Account, the new owner will not be able to use it fully, and you risk losing control of your data or, conversely, getting locked if the device is stolen.
The process of deleting a number (in the sense of linking an account) requires a complete log-out from all services. SIM-Xiaomi's security system, Find Device, tightly ties the device to your account, and if you just reset your device without first logging out, the phone will require a password from your old account when you turn on.
To perform the procedure correctly:
- 🔒 Go to Settings. → Mi Account.
- 🔒 Click on your profile and select “Log Out” or “Delete Account».
- 🔒 Enter a password to confirm the action.
- 🔒 Make sure that your smartphone is no longer displayed as active on the i.mi.com list of devices.
💡
Before selling your phone, make sure to back up your data to your computer or the cloud, as detachment of your account is often accompanied by cleaning up local data.
Also, be sure to untie the number from other services such as Google Pay (if used), messengers (WhatsApp, Telegram) and social networks. Two-factor authentication in many services is tied to your phone number, and access to it from the new owner of the device can create problems with regaining access to your personal accounts.
Full reset (Hard Reset) as a method of removal
If your question “how to delete a number in Xiaomi” means wanting to completely clear the phone of all traces of previous use, including contacts, history and accounts, then you need a complete reset to factory state.
Before you start, make sure you follow all the steps to untie your accounts described in the previous section.Resetting your settings without leaving your Mi Account will result in Activation Lock, and the phone will become a useless brick for anyone who doesn’t know your password.
There are two main ways to perform a reset:
- Through the settings menu: Settings → About the phone → Resetting → Erase all data.
- Using Recovery Mode: Turn off your phone, press the Volume+ button and Power at the same time, then select Wipe Data.
What happens to the data when it is reset?
Once the process is complete, the phone will restart and begin its initial setup, at which point neither your number nor your contacts will be on the device, and this is the most reliable way to ensure that personal data does not fall into the wrong hands.
Technical aspects: IMEI and number lock
In rare cases, users are interested in deleting a number in the context of a carrier locking a device over IMEI. If a phone is lost or stolen, the owner can ask the operator to lock the device. In this case, "delete the number" means to disconnect the SIM card from the network, but the phone itself (its IMEI) is blacklisted.
It is important to distinguish between the concepts: a phone number (MSISDN) is a virtual address on the network, and IMEI is a physical identifier of equipment. Deleting IMEI by software on modern Xiaomi smartphones is almost impossible without special equipment and knowledge, and trying to do this (IMEI firmware) is illegal in many countries.
If you bought a used phone and it is blocked by the operator by the number or IMEI of the previous owner:
- 🚫 Contact the seller to unlock.
- 🚫 Contact the operator with the purchase checks (if you are the legal owner).
- 🚫 Check the device for credit obligations (often phones sell without paying off the loan).
⚠️ Note: Buying phones with "cleaned» IMEI or unlocked through third-party services (R-Sim and analogues) carries high risks. After updating the firmware or changing the region, such devices may cease to catch the network.
In a normal situation, the user does not need or is not recommended to interfere with the operation of communication modules at the IMEI level. All number management operations should be performed through standard configuration interfaces or at the mobile operator.
💡
Cleaning your phone before selling requires not only a reset, but also a pre-exit from your Mi Account and Google Account, otherwise the device will remain locked.
