Sim lock for SGH - J700i?

Answer 1

Power on your phone, enter *#7465625# (*#simlock#)

make a note of what codes are active.

insert the SIM card about half way only.

Power on phone, it should come up and say "insert SIM"

at this point you do NOT insert the SIM yet

Enter *2767*3855#

this will wipe the settings on the phone and cause it to reboot.

Before it reboots, push the SIM card in fully

After a reboot, the phone should be working with that SIM,

whether or not it was able to work with it in the past.

Your phone is NOT yet unlocked.

For each of the locks that were active in step one reset the lock codes:

Network Lock: *7465625*638*00000000*00000000#

CP Lock: *7465625*27*00000000*00000000#

SP Lock: *7465625*77*00000000*00000000#

Subset Lock: *7465625*782*00000000*00000000#

Then, to disable the locks:

Subset Lock: #7465625*782*00000000#

SP Lock: #7465625*77*00000000#

CP Lock: #7465625*27*00000000#

Network Lock: #7465625*638*00000000#

Once this is completed, you can verify that all locks are inactive,

enter *#7465625# again.

SIM/Phone Lock are set in the security menu and can be disabled/enabled at your convenience. They are not important for this procedure.
