I have a viewty ku990 v1.0 locked on orange, when I put the sim in it come up with inactive usim. I would like to unlock my phone so I use my old o2 sim.

To remove usim locked you need to get unlock code. You can get unlock code at

They can supply unlock code for any LG. Once you have it you just type unlock code via phone keypad.

You MUST have sim card from network phone is locked to to be able to access phone menu! Without such sim card do not purchase unlock code.

Forgot password phone locked.

The unit shouldn't have locked-up...just reset itself. It would have wiped the data and settings, rebooted and started out as brand-new.

If it has truly locked-up, try removing the battery and re-inserting it. The unit should then boot up. If it doesn't, I would suggest calling your service provider for assistance.

The phone is locked to tmoble and i have an at&t sim card. how do i unlock the phone?

If it is a network lock you need to contact you're service provider for the unlock code.
If it is a key pad lock kindly enter wrong password for 10 time's you're handheld will get wiped. Then it will ask for the reset password enter the new password and remember that. (No data will be available when your Handheld is wiped)

How do I know if it's locked?

Locked it means the your phone will only work with one network sim card. ie vodaphone and just vodaphone.
Unlocked means will work with any sim from any network or country

to test just but a different sim card in (differnet network) if it ask for sub password you phone is locked

Try with all the code to see whether you can get one to unlock your phone. If all still cannot help then you can only contact Samsung Support for help. I hope these information below at least can give you some hints:

Note try codes which help direct unlock for either SIM Lock or Security Lock first before try other codes

*7465625*746*Code# = Enables SIM lock
#7465625*746*Code# = Disables SIM lock
*2767*2878# (Temporary Unlock)
*7465625*638*00000000*00000000# (Set Code)
#7465625*638*00000000# (Clear Network Lock)
*#7465625# (Verify the network lock is “inactive”)

*2767*3855# - FULL E2P RESET
*2767*2878# - CUSTOM E2P RESET
#*7337# - UNLOCK
*2767*688# - UNLOCK
*#0523# - CONTRAST
*#9998*523# - CONTRAST
*#8999*8378# - Service Menu (X100)

First with different carrier SIM in phone at WRONG CARD screen ENTER on the keypad
*2767*3855# (wait 10-15 seconds) phone will reboot(restart)
When phone completes reboot ENTER
AND THEN *#7465625# to check the locks....all locks are inactive...these are all the locks...
network lock - inactive
subset lock - inactive
sp lock - inactive
cp lock - inactive
sim lock - inactive
activa lock - inactive
phone lock - inactive
auto network - inactive
auto subset lock - inactive
auto sp lock - inactive
auto cp lock - inactive

Good Luck
