Hi I have a samsung E250 has not been used for a year it is frozen and asking for a code I have put in new sim as well who do i go to samsung or old pre paid sim was with optus


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....

Unlock code for samsung sgh-d780 midnight pool


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#)

My samsung A437 reads insert sim card ans sos. The sim card is in there and we know it works since it can be used in other phones


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.

I need to unlock my puk code for samsung a437 phone


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.

Forgot Security Code


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)
