| Method | How It Works | Steps (simplified) | Pros | Cons |
|--------|--------------|--------------------|------|------|
| IMEI‑based network unlock | Submit the device’s IMEI to an online unlock service that uses the manufacturer’s database. | 1. Dial *#06# to get IMEI.2. Visit a reputable free‑unlock site (e.g., UnlockYourPhone.org).3. Enter IMEI, select “ZTE ZXV10”.4. Receive an unlock code via email.5. Insert a non‑original SIM → prompt for code → enter it. | No software flashing; preserves warranty. | Requires a working internet connection; some sites may request a small verification fee (avoid). |
| ADB‑based bootloader unlock | Uses Android Debug Bridge to send an unlock command to the bootloader. | 1. Enable Developer Options → USB debugging.2. Install ADB on PC.3. Connect phone, run adb reboot bootloader.4. Execute fastboot oem unlock (may prompt for confirmation on device). | Works even if the carrier lock is “hard”. | Wipes all data; may void warranty; not all ZTE builds allow OEM unlock. |
| SIM‑swap “network code” | Some carriers publish generic unlock codes for specific firmware versions. | 1. Identify firmware version in Settings → About phone.2. Search for “ZTE ZXV10 B866V2 unlock code <firmware>”.3. Enter the code when prompted after inserting a foreign SIM. | No third‑party tools needed. | Codes are rare; often outdated after OTA updates. |

Grant root/ADB permissions as instructed.3. Run the app → it displays an unlock code. | Completely offline; no internet trace. | Requires root or unlocked bootloader; security risk if APK is tampered. | This is the core of the free method
