When you purchase a Xiaomi smartphone through a carrier or network provider, the device is typically locked to that specific carrier. This means the phone will only accept SIM cards from the network that sold it. Unlocking a Xiaomi phone by IMEI removes this carrier restriction permanently at the hardware level, allowing you to use any compatible SIM card from any network worldwide.
The IMEI number — International Mobile Equipment Identity — is a unique 15-digit code assigned to every mobile device. When you submit this number through an IMEI unlock service, the service communicates with carrier databases to authorize your Xiaomi device for use on other networks. This is fundamentally different from software-based workarounds, which are temporary and often invalidated by system updates.
Understanding the difference between SIM unlock and carrier unlock is important before proceeding. A SIM unlock removes the network restriction placed by your carrier, while carrier unlock refers to the broader authorization process. Both refer to the same underlying outcome: your Xiaomi phone becomes free to operate on any GSM or LTE network.
There are several practical reasons why Xiaomi users seek an IMEI unlock:
Locked Xiaomi phones force travelers to use expensive roaming plans. After unlocking, you can insert a local SIM card in any country and pay local rates.
If you want to move to a better carrier with improved coverage or lower pricing, a locked phone prevents you from doing so without purchasing a new device entirely.
An unlocked Xiaomi phone holds significantly higher resale value than a carrier-locked device. Potential buyers are not restricted to a single carrier, which widens your potential market.
Many Xiaomi devices support dual SIM functionality. An IMEI unlock allows both SIM slots to operate freely across different networks, which is particularly useful for separating personal and business lines.
Xiaomi's custom MIUI interface and the newer HyperOS are region-specific in some builds. Unlocking your device often coincides with using an international ROM, giving you access to Google Play services and region-unrestricted features.
The IMEI unlock process covers a broad range of Xiaomi devices. The following series are commonly supported through official IMEI unlock services:
Mi 10, Mi 11, Mi 12, Mi 13, Mi 14, and their Pro, Ultra, and Lite variants.
Redmi Note 11, Redmi Note 12, Redmi Note 13, Redmi 9, Redmi 10, Redmi 12, and Redmi 12C. If you are looking to get a Redmi unlock code free , there are verified service options available.
POCO X3, POCO X4, POCO X5, POCO F3, POCO F4, POCO M3, and POCO M4 Pro.
Including Xiaomi 13T, 13T Pro, 14T, and 14T Pro with both Snapdragon and MediaTek chipset variants.
Before placing an unlock order, you need to locate your device's IMEI number accurately. There are multiple methods:
Open the phone app and dial *#06#. Your IMEI number will appear on screen immediately. Xiaomi dual SIM devices will display two IMEI numbers; use IMEI 1 for the primary SIM slot.
Go to Settings > About Phone > All Specs > Status > IMEI Information.
If you have the original retail box, the IMEI is printed on the barcode sticker on the back or side.
On some Xiaomi models, the IMEI is printed on the SIM card tray itself.
The IMEI unlock process for Xiaomi devices follows a structured sequence. Here is the complete procedure:

Before submitting an unlock request, confirm that your Xiaomi phone is eligible. Devices reported as stolen, blocked, or flagged with an outstanding financial balance may not qualify. You can run an unlock eligibility check to confirm your device's status before proceeding.

The unlock code generation depends on knowing which carrier locked your device and in which country. For example, a Xiaomi phone locked to AT&T in the United States requires a different database query than one locked to a European carrier. Make sure you have this information ready when placing your order.

Visit the IMEI services order page and locate the Xiaomi unlock option that matches your carrier and model. Enter your 15-digit IMEI number accurately. A single digit error will result in an incorrect unlock code being generated.
Many users search for alternative Xiaomi unlock methods before settling on IMEI-based unlocking. Here is how the methods compare:
Xiaomi does offer a bootloader unlock program, but it requires a Mi account, a waiting period of up to 72 hours or more, and voids the warranty on most devices. It also does not directly address SIM carrier locks.
Various apps claim to unlock SIM restrictions. However, as detailed in our review of SIM unlocker apps for older phones, these tools rarely work on modern Xiaomi devices running MIUI 12 or later and HyperOS. They are not recommended.
Contacting your carrier directly to request an unlock is theoretically possible, but carriers impose strict eligibility criteria — often requiring the account to be active for a minimum period and the device balance to be paid in full. Processing times can be unpredictable.
The IMEI unlock method is the most reliable and permanent solution. It works across all Xiaomi variants, does not require a Mi account, does not affect the warranty in terms of software operation, and delivers a factory-level unlock recognized by all networks.
The most frequent cause of unlock failure is a mistyped IMEI. Always double-check the number before submitting.
If your device is locked to one carrier but you select a different one during the order process, the generated code will not work. Verify carrier lock status first.
If your Xiaomi phone's IMEI has been blacklisted by the carrier due to theft or unpaid bills, standard IMEI unlocking will not bypass the blacklist. Use the IMEI blacklist check tool to verify status before ordering (note this tool also applies to Android devices in terms of blacklist database cross-referencing).
Some Xiaomi devices sold in specific regions are configured with carrier-level restrictions baked into the firmware. An IMEI unlock addresses the carrier SIM lock but does not modify firmware region settings. Consult the full device specification checker to understand your device's regional configuration.
Yes. IMEI unlocking is legal in most countries. In the United States, the Unlocking Consumer Choice and Wireless Competition Act explicitly permits consumers to unlock their devices. In the United Kingdom, the Communications Act supports the right to unlock after the contract period ends. In India, the European Union, and most other jurisdictions, carrier unlocking is permitted under consumer protection principles. The method used by reputable IMEI unlock services — submitting your IMEI to official carrier databases to generate an authorized unlock code — is entirely within the bounds of the law and carrier policies.
IMEI unlocking uses official carrier authorization systems without modifying your Xiaomi hardware or software.
