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. :)

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.

Can't unlock Samsung Hue?


samsung hue r500 and having problem when accidentally or curiously selected nam2.. after it powers off then on again by itself, it brings u to a little window (initial programming needed) and the enter code (password). as you will notice none of your 4 digit passwords will work, default wont work, u have to push the back or end call button to get away from the enter code window. enter ##626# and hit send button. it will bring u to option to select nam1 or nam2, select nam1.. go to next screen, enter in the sdc code which is 000000, (6 zeros), enter or next screen, make sure that mid is same as ur cell number, go to next screen, it will show ur number again, next screen, will be sid and nid numbers... they are what they should be, go next screen, then i think there is option to be done, view, edit choose done, next screen then it will program by itself. powering on then off, bringing u back to same screen with the same window of initial programming needed, just go to enter code, and enter the last 4 of your cell number, and it will let u through,.. just remember to go back in to your phone options menu and change the nam setting in there back to nam1 also. then it will power off and on again. program should be complete... you can always also dial *228 and option 2 to reprogram your phone again to make sure.

Changed nam1 to nam2 on samsung sch-r410 now it wants initial programing and a key code


Well by now you probably already solved this problem. This is for future references of anyone else who come across this. The steps are easy and simple.
1st, dial #43574357*
2nd, u should be at a device info menu. select system info.
3rd, your password is the last 4 digits of your MDN number.

now u can access your phone and change back to NAM1

Lock code for nam2 settings


Ok i sent an email to sumsung and i got this response

Thank you for your email. If you switched the NAM to NAM2 you will need to calculate the code. Listed below are the steps on how to do so:
1.Obtain the Hexadecimal ESN of the phone. The ESN should be printed on the sticker on the back of the phone, under the battery. The Hexadecimal ESN is the one with letters and numbers.
2.Open Windows calculator by going to Start -> Run -> type in "calc", then click OK
In the Calculator, click "View" then "Scientific".
3.Click on Hex and type in the Hex ESN
4.Click on Dec for the decimal conversion and use the last four digits for the code on the handset
5.Once the code is entered and the menu can be accessed, switch the NAM to NAM1

Cant unlock my phone


If you know your original lock code, take it in to your service provider, each code is diffrent and can only be programed manually, if you dont know your original lock code you will have to sacrific all info pics,mess,numbers, etc. by a reset... I can guide you through the steps to erase all if you lost your Unlock code, or switch back to nam1 if you know your lock code, ( when you switch back, if security is on automatic lock, password is required) intial programing code is not your Unlock code.
