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. :)

Need unlock code for delve samsung


You can unlock it by flashing your mobile if your mobile is a CDMA mobile...
The procedure for flashing your mobile is in the link below
http://hubpages.com/hub/How-to-Flash-your-cell-phone
It has an video explanation.

If your mobile is not an CDMA mobile , you can get the network unlock code(NUC) by just contacting the current network provider2_bing.gif customer caredepartment.It is free of cost.

Therestrictioncodecan be got from your old service provider..This restriction code iskeptto prevent someone who stole themobile from using it withanotherprovider...

They will have a security check done with your date of birth etc..to verify whether you are the exact owner of the phone..

After that they will provide you the restriction code to unlock it and use it with another service provider..

Hope I helped

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

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.
