Dismantle router and remove module
Connect it to computer by your preferred method. We have used PCI module to USB adapter, but possible by other methods, like attaching it to notebook directly
Open device manager and locate module under "other devices", it should have "!" or "?" marks next to it. Download drivers. Apply downloaded drivers manually for each line of module. When installed it will appear under "Modems" and "Ports" section
Launch DC-unlocker
Select manufacturer "Gemtek", leave select model as "Auto detect (recommended)", click detect button - big magnifying glass
Wait till DC-Unlocker fully detects module
Open Server tab, enter your username and password that you received after credits purchase. Click "Check login". (you can buy credits here www.dc-unlocker.com/buy).

After you see that device was successfully unlocked, put it back into router. Now it will work with other operator sim cards.
