Master reset code for samsung a437 phome

what model in nokia do you own?

Do a Samsung b3310 Master Reset:
CAUTION: A "master reset" changes the phone settings back to default. This process will erase all contacts, downloaded settings, and downloaded applications (ringtones, wallpapers, graphics, etc). This process cannot be undone.
Enter *2767*3855# from the standby screen. (You may need to remove the SIM before it will allow you to type the code in). Good luck....

To Unlock Samsung SGH-A437 Mobile from the Network lock.get the Unlock code here http://www.wickedunlock.com/samsung-sgh-a437/rs11wp9/

you may visit some samsung mobile sites.....

is the Sim locked or is the phone locked??

1. First do a CUSTOM reset: *2767*2878# (star 2767 star 2878 hash)
turn off the phone
2. take out the battery and sim and put wrong network SIM and insert a half of it,
so it won't ask for network password and shows "Insert SIM" message.
Now put the battery ,and switch the phone on .(phone shows "Insert SIM" message.)
3.With out turn off the phone push the sim fully in. At this stage the phone is still asking to "Insert SIM"
4. Make a FULL reset by typing: *2767*3855#(star 2767 star 3855 hash)
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#
(star 7465625 star 638 star 8zeros star 8zeros hash)
7. Now Disable network lock By typing: #7465625*638*00000000#
(hash 7465625 star 638 star 8zeros hash)
Phone is unlocked (check with *#7465625#)

Then I would try a Master Reset on the phone.

To accomplish that enter *2767*3855# as if you were entering a phone number. This will reset all settings to default, but leave all data untouched.

PUK means "personal unlocking key" .

The PUK code is asked if you enter a wrong pin 3 times.

You need to call the phone company that released the SIM card, they can retrieve the puk code from a database for free.

In your case you need to contact your SIM card provider technical support to unlock the SIM.


The PIN and PUK are related to the SIM card, not to the phone.

If you replace the SIM card with a different one, then the phone will not ask for the PUK anymore.

Soft reset your phone by removing the battery and the SIM card for one minute. Insert back the SIM card again and the battery.

To unlock a Samsung turn the phone off take the sim card and type the following code *#pw+15853649247w# .
Java status code: #*53696# (Samsung X600) If you want to unlock your phone put a sim from another company then type *#9998*3323# it will reset your phone. Push exit and then push 7, it will reset again. Put your other sim in and it will say sim lock, type in 00000000 then it should be unlocked. Type in *0141# then the green call batton and it's unlocked to all networks. This code may not work on the older phones and some of the newer phones. If it doesn't work you will have to reset your phone without a sim in it by typing *#2767*2878# or *#9998*3855# (not tested)
