SOURCE: My Cellphone Model No: Samsung SGH J700 is been Locked

two codes you need to know!

FULL RESET: *2767*3855#
NETWORK: *#9998*638#

Basically first do a Full Reset (this is deletes Everything saved on the phone; But this is isnt the firmware so its safe)
Then insert whatever SIM card you want and type in NETWORK (*#9998*638)... your phone will freeze for a sec (this is normal) and the restart... youll get a message saying "Please Wait..." and then you phone is working

NOTE: The NETWORK (*#9998*638#) code has to be typed in every time you start the phone

MY o2 j600 (J600AYGF1) was "Phone Locked, Return to service" and then i used this code and it was fine...
My j600 is now back to normal by typing #0111*RANDOMCODE# and the incorrect password message came up and tyhen worked
!!!!!!!!BUT PLEASE DONT DO THIS COZ IT WAS LUCKY!!!!!!!!

Can u find me a code to unlock Samsung galaxy exhibit IMEI 359874041306247. THANKS


Hello. You can definitely unlock your T-mobile network locked Samsung Galaxy Exhibit using unique unlock code. You can get the unique unlock code for your Samsung Galaxy Exhibit from Mobile-Unlocker.com at affordable cost with an easy unlocking guide. But you can unlock a GSM network locked phone to use any other GSM network SIM card only. Verizon is CDMA network provider. You cannot use it with the unlocked phone.
