SOURCE: i need the network unlock code for samsung SGH -E390

To unlock your samsung mobile,follows these steps
Do a custom reset:
*2767*2878# once this has finished rebooting turn the phone off.

Next a SIM card from a different service provider needs to be pushed half in - (Push it fully in then slide it back out by about 1/2 a centimeter),
Turn on the phone - you will now see an "Insert SIM" message,

Now perform a full reset:
*2767*3855#

When the phone powers off, quickly push the SIM card fully in, and let
the phone power back up.

After you do the reset, check and make sure that your Network lock is active by pressing *#7465625#

If it isn't active you must use this code to reactivate it:
*7465625*638*00000000*00000000#

Then you have to deactivate the SP lock first. To do that you need to input:
*7465625*77*00000000*00000000# (this will reset the lock)

Then you enter:
#7465625*77*00000000# (to disable the SP lock).

Then you disable the Network lock:
#7465625*638*00000000#

The phone is finally unlocked.

the number you typed is a complete erom reset. sometimes this dosen't work and crashes the phone.
your only option now is a phone repair shop or sending handset back to samsung for factory reprogram
