Think it is the last four digits of your mobile number.

I have a samsung reality. i was fooling around with the settings & set it to NAM2. it's now locked i need a 4 digit code. i've tried all the online suggestions nothing works. i've been up for 4 hours...


Using the default "last four digits" unlock code will not work because switching to NAM2 changes your phone number, and hence changes the default unlock code. You have to find out your new phone number (and new unlock code) under NAM2. Do this:

  • Get to the dialer screen.
  • Dial #43574357* (#helphelp*)
  • Tap "1. system info"
  • The top two entries, MIN and MDN are your new number. Usually they are invalid phone numbers (000-000-????) but the last four digits are your unlock code. Write them down or remember them.
  • Get back to the unlock screen, type in the code.
  • Go directly into the menu and change back to NAM1
  • Don't do that again. :)

I recently switched my NAM for NAM1 to NAM2 at first everything was fine it rebooted and everything but at start up it asked me for a four digit unlock code i was like what the heck i dont have an unlock...


the default is always one of these code try them all the last four digits of the phonenumber last programmed in the phone aka your number or 9999,1234,4321,0000,1111 if none of those work you can go the retail store for a flash they hook it to the computer and push software to the phone to correct the issue it takes five mins and its free its a common issue for them to correct if you change your lock code from the default in the future always set up a dummy contact with it in there so that you can easily look it up also please vote for me I'm trying to work my way up to expert level and I cant without your vote please

I cant remember the unlock code for my samsung phone


UNLESS YOU HAD A PERSONALIZED CODE, TRY 1234. MOST PHONES COME PRE PROGRAMMED WITH THIS CODE.

Switched to NAM2 and do not know the lock code.


Dial *22899 and press SEND to program the phone.
after it has finished downloading the programming information, the phone will reset.
The Lock code will now be set to the last 4 digits of your phone number.
when you have finished, be sure to switch back to NAM1 and dial *22899 again to re-program it.
