Is LG CU400 your mobile model? If it is so then unlock it from its network lock using unlock code. Contact your service provider to get the code. If they failed to provide or ask you to wait for long period it is better to get the code from online providers itself. There are lot of online sites available to provide unlock code like eBay, amazon etc... But i have found the site Unlock-Zone.com ,through my search and i have unlocked my LG mobile in that site itself. You can also try the same site to unlock your Mobile easily and safely.

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.

Lg cu400 cell phone IMEI # 011071003749585


The default lock code (security) is 0000. and default, PIN1 is 1111, and PIN2 is 2222
If you need further help let me know. If you get it wrong enough you will be asked to enter PUK code. Then you only need to call up your provider and they will assist you.
Thanks,
Lee

Lg cu400


You should try the last 4 digits of your cell phone number, if you have changed the default lock code and don't remember it, you will need a little more advance tools to unlock it, you might wanna check and see if you service provider has a repair center in town for a quick lock code read.
if you have the Software drives and cables for it you could use BitPim which is free online. If not, you will need to contact your cellphone customer service reps and find out if any repair centers, if no luck, try to track down a US Cellular repair shop and sweet talk them into reading lock code for you.
Hope this helps
