boss nemson999, I have been looking for way to unlock my WM66A about three years ago. I tried dccrap to no avail so I just kept this modem in my drawer and did not use it anymore. I then bought a HuaWei E355 but still wondered how to unlock this WM66A up until this evening. I tried out your procedure and it worked the first time. THANK YOU, THANK YOU, THANK YOU. Now I will be using this WM66A with a Globe Tatoo as a backup and use my E355 with a Smart Bro as my main wireless connectivity device when I am out of town.
