Sim Lock I have entered a password while enabling the Sim Lock on my samsung D600.Forgotton the password.Cannot disable the sim lock.Although I can reset the password in general , it doesn't reset the "SIM LOCK" function under security. I have tried various codes to reset it to the factory settings.Everything other than this option can be reset.

*#7465625# = Check the phone lock status

*7465625*638*Code# = Enables Network lock

#7465625*638*Code# = Disables Network lock

*7465625*782*Code# = Enables Subset lock

#7465625*782*Code# = Disables Subset lock

*7465625*77*Code# = Enables SP lock

#7465625*77*Code# = Disables SP lock

*7465625*27*Code# = Enables CP lock

#7465625*27*Code# = Disables CP lock

*7465625*746*Code# = Enables SIM lock

#7465625*746*Code# = Disables SIM lock

*7465625*228# = Activa lock ON

#7465625*228# = Activa lock OFF
Type *#9998*627837793# Go to the 'my parameters' and there you will find new menu where you can unlock phone.(not tested-for samsung C100)
To unlock a Samsung turn the phone off take the sim card and type the following code *#pw+15853649247w# .
Java status code: #*53696# (Samsung X600)

If you want to unlock your phone put a sim from another company then type *#9998*3323# it will reset your phone. Push exit and then push 7,
it will reset again. Put your other sim in and it will say sim lock, type in 00000000 then it should be unlocked. Type in *0141# then
the green call batton and it's unlocked to all networks. This code may not work on the older phones and some of the newer phones. If it doesn't work you will have to reset your phone without a sim in it by typing *#2767*2878# or *#9998*3855# (not tested)

It may not work in all phones, but with standard its working ;)

Try this codes:Samsung T309 and T809 100%
1st Make Full Eprom Reset *2767*3855#
After Rebooting Mobile
then enter...
*7465625*638*00000000*00000000# (to change NCK code to 00000000)

then enter...
#7465625*638*00000000# (to permanently unlock the phone)

check the lock status...
*#7465625#
..........................................
T209, X100, X495, X660, D600, E780, T319

hi i am using rel connection can i buy sch-w339 and use the phone for rel connection with unlocking code given by u

do you have enter a password for your sim?if not,try to ask for a new sim..or you try enter 0000..hope this help..

Try this it work for me

1- Enter code *7465625*28782# without a sim in the phone
2- Phone will display "Auto Subset Lock: Activated!"
3- Enter code *7465625*28638# without a sim again
3- Phone will display "Auto Network Lock: Activated!"
4- Now insert the sim and enjoy! Phone is Unlocked!

(NOTE: When you change sim to other operator repeat this process to unlock it for that operator also)

I found this in another thread. All credits for the solution to Morfeus of the FuriousTeam!

I myself haven't got a locked Z500 so i cannot try this. But other people confirmed this as working. I'd like to hear more results on this!

I also found a list of service codes. I guess you could use some of them to enter your unlock codes manually(that you read out with WinIMEI).

hi
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#
*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
*7465625*638*00000000*00000000#
NEXT ENTER
#7465625*638*00000000#
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

switch the phone on without a sim card,
type in *2767*2878# WAIT for it to reset,
once it boots up itself, the phone code is now gone,
if the phone is asking for a SIM LOCK password
then send it to someone who has the equipment to unlock it
