Unlocking LG CU 400 (AT&T) phone, IMEI starting with 0

I have a LG CU400 (AT&T) phone whose IMEI starts with 0. I need to unlock it to use it in India i.e. for GSM 900 & 1800 band. Can this phone be unlocked & used in 900 / 1800 band? I have been told by someone that it can't be because the IMEI starts with 0.

    Thanks. So just to clarify:

    It doesn't matter that the IMEI starts with 0. Even then when I unlock this phone it should work in 900 / 1800 MHz. Right?

    & yes, I have already crossed 90 days.

Free unlock code for lg cu400


Using a free unlock code is very risky. It is not 100% safe and accurate and may harm your mobile phone. The best way to get the LG cu400 unlock code is through an LG UNLOCK CODE website. Use the IMEI unlock code provided by them and your phone is 100% sim lock free.
