    For most Android phones, a SIM card is completely optional. You only need a stable Wi-Fi connection and a computer with ADB and Fastboot tools. how to unlock bootloader without sim card

    Enable Developer Options: Go to Settings > About Phone and tap Build Number 7 times.

    Xiaomi officially requires a SIM card with mobile data to "bind" your Mi Account to the device. If you cannot use a SIM, your options are limited:

    Borrow a SIM: You only need the SIM to initiate the "Add account and device" step in settings. You can remove it immediately after the account is successfully bound and wait the required period (usually 168 hours) using Wi-Fi.

    MediaTek Exploits: If your device has a MediaTek (MTK) processor, tools like MTKClient may allow you to bypass the official unlock tool and SIM requirement entirely.

    HyperOS Bypass: Some community scripts on GitHub attempt to bypass account binding requirements, though these are technically complex and may be patched by Xiaomi.

    Important Disclaimer: The following guide is for educational and informational purposes only. Unlocking a bootloader will typically wipe all data on the device (factory reset). Additionally, modifying your device's software may void your warranty, brick the device, or cause security vulnerabilities. Proceed at your own risk.

    Before proceeding, it is vital to understand the difference between two often-confused terms:

    The Verdict: You do not need a SIM card to unlock a bootloader. You only need an active internet connection (Wi-Fi) to communicate with the manufacturer's servers to retrieve an unlock code or verify a token. The computer you use for the process acts as the primary interface, not the cellular network. In some cases, users may be able to

    If you have a backup or secondary SIM card, you can use it to unlock the bootloader. This method is straightforward: simply insert the SIM card, follow the manufacturer's instructions, and unlock the bootloader.

    This is for phones that are carrier-hard locked (Verizon-branded Pixels, AT&T Samsungs, locked Xiaomi). The only way without a SIM is physical.

    What are Test Points? Two tiny metal contacts on the phone's motherboard. Shorting them forces the phone into Emergency Download Mode (EDL).

    Process (Highly Advanced):

    Risk: This voids warranties, requires micro-soldering skills, and can brick your device. Only attempt if you are ready to lose the phone.

    Google Pixel phones, along with Nokia (stock Android) and Motorola (near-stock), are the most SIM-independent devices.

    Requirements:

    Steps without a SIM card:
