Sigma Key is a hardware dongle/software combo. It is the most expensive but the most reliable.
Best for: ZTE phones with MediaTek processors (e.g., ZTE Blade A3, ZTE Avid). Most budget ZTEs use MediaTek chips. This free tool disables FRP by exploiting the preloader USB driver.
Requirements: Windows 10, USB 2.0 port, MTK drivers. Verdict: Incredibly effective if you can follow YouTube tutorials.
Many budget ZTE phones (ZTE Blade A3, A5, Z232) use Unisoc processors. These require a different approach.
