How do tyou unlock your phone if you changed the setting to nam 2


So you're playing with all the settings in your phone and you notice this nice security menu. Wow, maybe you should enable the lock code. But you don't want to have to enter the lock code all the time, so you set your phone to only need a code when it turns on. Ah. Some piece of mind. What's this other sub-menu? Network? What's a NAM? Hmm. Let's set NAM 2 and see what happens. EEEK! Your phone's rebooting. Why's it doing that? Okay. Here's that new prompt for the security code. It's okay. I remember it's the last 4 digits of my phone number. Oh No! That didn't work. Unfortunately, when you switched to NAM 2, you switched your phone over to a different phone number. Your code's no good. Your phone is useless.

There are 2 solutions. The safest and best solution is to take your phone back to Verizon and have them reprogram it. A few people have told me Verizon is uninterested in doing this. A more risky solution is below. It will reset your phone to its original settings and erase all your phone numbers you have in the phone but it should get your phone working again. I've never had to fix this problem on my own phone, but a bunch of people have emailed me their thanks to say that this works. If this doesn't work or you make it worse, please don't blame me, especially if you don't follow the directions very carefully. I believe this proceedure works, but there is one mistake that if you dial a 9 at just the wrong moment, then you're going to be guaranteed making a trip to Verizon (so speaks the voice of experience). So, without further ado, here's the proceedure:
Do this exactly:

  • With your phone on, dial 47*68#13580
  • This will bring up a menu that says something like "-TEST CDMA-"
  • Dial 22
  • Your phone will now say "Send NAM 2"
  • Dial 222222 (the number 2, six times)
  • With each key press two digits will appear on your screen. Something like "000000-84100". Write down the 3 digits after the dash (e.g. 841). These are the first 3 digits of your unlock code.
  • Dial #
  • Dial 73
  • Your phone will say "Clear All." and it will just sit there for a while. Don't panic, just let it clear all the settings. It's not clearing the programming, just all the ringers and key beeps and menu settings that you entered (and more importantly, its reseting your password to something predictable). After about 30 seconds a "." will appear after the 73 you dialed. when that happens, the menus are cleared.
  • Dial 02
  • This will reboot your phone.
  • When the phone finishes restarting try the 10 possible security codes that start with the 3 digits you wrote down (e.g. 8410, 8411, 8412, 8413, ...). One of those codes should work.
  • When your phone is unlocked, switch back to NAM 1 by pressing Menu, 0 for Setup, 2 for Network, 1 for Set NAM, and select NAM 1.

I changed over to other nam and powerd down phone


PLEASE BACK UP YOUR FILES BEFORE UNLOCKING
This will also bring the phone to default settings
1. First do a CUSTOM reset: *2767*2878#
turn off the phone
2. take out the battery and sim and put wrong network SIM and insert only a half of it,
Very important so it won't ask for network password and shows "Insert SIM" message.(possibly in a different language)
Now put the battery ,and switch the phone on .(phone shows "Insert SIM" message.)
3.push the sim fully in at this stage the phone is still asking to "Insert SIM"
4. Make a FULL reset: *2767*3855#
5. The phone should reboot working with "wrong" sim inside.
6. Make a Change the NCK password to 8 zeros by typing: *7465625*638*00000000*00000000#
7. Now Disable network lock By typing: #7465625*638*00000000#
Phone is unlocked

Changes NAM Settings?


Here's some ideas for unlock codes, most phones use the last 4 or possibly 7 digits of the phone number, 4 or 5 - 0's or 12345.
Basically your NAM settings contain the phone number info for a carrier, and you can put two different numbers in the same phone using NAM1 and NAM2, what you have done is switch it to an empty NAM so it is asking for the rest of the programming info to set it up.If you can switch it back to NAM1 it should work again. Most phones have an option in the menu for phone settings that allows NAM switching without needing a code.
