7.7 Security

The Security menu allows you to

secure the phone electronically.

1. Open the flip and press

[MENU]

2. Press Settings & Tools.

3. Press Phone Settings.

4. Press Security.

5. Enter the four-digit lock code.

The lock code is the last 4 digits

of your mobile phone number if

it is set. The lock code is the last

4 digits of your MEID if your
mobile phone number is not set.

*#06# for checking the IMEI (International Mobile Equipment Identity) for Nokia 7210 To view Week and Year of manufacture enter *#3283# [*# D A T E #]
The last two digits are the year. If the year is 95, the first two digits are the month. For 96 the first two digits are the week of the year.

To view the software version on Nokia 7210 enter *#170602112302# or *#9999#
On newer phones, the code has been changed to *#682371158412125#

All Nokia phones (Nokia 7210 and newer) have four different SIM locks which can be used to lock the phone for up to 4 different providers. But most phones with restriction only have one lock activated. (Lock 1)

The main code used in Nokia 7210 phones is :
#pw+(master code)+Y#
This code is able to check, activate or remove Sim card restriction (SP-lock).
Use the * key to get the p, + and w chars.
'Y' has to be 1,2,3 or 4 - depending of what lock you what to deal with.

#pw+1234567890+1# for Provider-Lock status
#pw+1234567890+2# for Network-Lock status
#pw+1234567890+3# for Country-Lock status
#pw+1234567890+4# for SimCard-Lock status

# = DOUBLE-CROSS
W = PRESS "*" THREE TIMES
P = PRESS "*" FOUR TIMES
+ = PRESS "*" TWO TIMES
MASTERCODE = 1234567890
Y = NUMBER 1 TO 4

(master code) is a 10 digit code, based on the phones IMEI number.

Eg. To remove restriction on lock 1 type following code:
#pw+(master code)+1#
If you just want to check your phone use 10 random numbers Eg. 1234567890 as the (master code)
eg. To check if phone if restricted on lock 1 type the following code:
#pw+1234567890+1#

Bypass the SP lock With a Nokia 16xx/21xx/31xx/51xx/81xx

1. Insert SIM card of different provider.
2. Turn on the phone and press the UP VOLUME key for 3 sec.
Then release it and the phone says PIN CODE?
3. Press the "C" key.
4. Then Press * and wait until it disappears and appears again, then press * one more time and 04*PIN*PIN*PIN#
(please help me as I helped you)

This problem was solved for me using only the Calculator application on my computer! The step-by-step instructions can be found here:

The same solution is spelled out at the Samsung support site:

Cheers!

usually your able to go into the menu and the either options or settings and click on security! but some phones are so dang complicated. lol here is what ive found its a razr 2 v9 right?its from the motorola website


codes & passwords
Your phone’s four-digit unlock code is originally set to
1234. The six-digit security code is originally set to
000000. If your service provider didn’t change these
codes, you should change them:
Find it: s >wSettings > Security > New Passwords
You can also change your SIM PIN or call barring
passwords.
If you forget your unlock code: At the Enter Unlock Code
prompt, try entering 1234 or the last four digits of your
phone number. If that doesn’t work, press s and
enter your six-digit security code instead.
If you forget other codes: If you forget your security
code, SIM PIN code, PIN2 code, or call barring
password, contact your service provider.
lock & unlock phone
You can lock your phone to keep others from using it.
To lock or unlock your phone, you need the four-digit
unlock code.
To manually lock your phone: Presss>
wSettings > Security > Phone Lock > Lock Now, then enter
your four-digit unlock code.
To automatically lock your phone whenever you
turn it off: Presss>wSettings > Security > Phone Lock >
Automatic Lock > On, then enter your four-digit unlock
code.

Providing you have not changed the code since purchase, by default the 4 digit code is set to four zeros(0000)

SIM pin code:
This is a pin code that locks the sim card until you enter the correct code. This protects your account, even
if your sim is put into another handset. To reset it, you need the PUK code:
Pin Unlock Code (PUK)
If you miss key (or forget) your SIM pin code, and enter the wrong one 3-5 times in a row, the SIM will lock up, and you’ll need to enter the PUK unlock code to release it. You should ask your Network Service Provider for this code when you need it. Don’t try to guess it, because after a few wrong guesses, the SIM card will be permanently disabled.
Phone Security Code:
This locks the handset, as opposed to the sim card. You can also set some handsets to only accept a “new” sim if the phone security code is entered. To reset it, you need the Master code code:
Master Reset Code
Sometimes known as the Master Code, this allows you to unlock a handset if you have entered the Security Code wrongly too many times.
Which is the one that you want?
The default security code for Nokia is 12345

you have to phone 07973100450 from a land line. it will ask you for your phone number a few times then it will pass you to  a REAL person who will ask you ask you a few security questions like what are the last four numbers of your top-up card and vol lia that is how you get your four digit id code!!!!!!!

hi

as youve entered the puk code, it asks for the new pin code, the default code was 1234 right? so if you are going to try the new pin code yu can either invent a new pin code or just enter the default code.

hope this helps.
