If you have a USB modem (dongle) model E1650, the "better" and most standard way to unlock it is using one of the following tools.

Option A: DC-Unlocker (Most Popular) This is the standard tool for unlocking 3G/4G modems and routers.

Option B: Universal Master Code Calculator (Free / Old Method) For older devices like the E1650, you might be able to generate the unlock code for free.

  • Reboot your PC – Critical for driver registration.
  • Launch the Tool – Navigate to C:\GSM_Tool\v1650\GSM_Unlock.exe.
  • Users report that v1650 has a 40% faster handshake rate compared to v1500. This means less time waiting for the tool to recognize your device and more time actually completing unlocks.
