Hey friend you can track your phone only if you had activated the mobile tracker on your samsung cell phone , otherwise you can't soorry to say that...!!!

Hi i've samsung b210 mobile. my mobile sim track slot has been distroyed.so please help me in fixing sim track slot immediatly

Have you tried another sim card? Maybe it's just the sim card that's locked

Hi,

Try this steps , hope it will help you:

Unlocking:

If you have Rev 1.5 (x426) or earlier and most older models
Use the *#9998*3323# Trick (look for it on the forum)
The *#1111*WHATEVER# code will NOT work

If you have Rev 1.6 (x426) or later and most newer models
You MUST use unlocking software. Codes WILL lock your phone FOREVER

Locked: Return for Servicing

There is only 1 working solution, you must flash a copy of the firmware that is not in the locked status. (Most) Unlocking programs will NOT disable this issue, and your service provider cannot give you a code

If you do not plan to use your phone with another service provider, there is no real point to unlocking your phone other than to sell it. If you don't need to unlock it, don't take the risk of disabling the phone altogether

The *#9998*3323# Method:

1. If you have changed your phone password, change your password back to the default 8 zeros (00000000).
2. Put a SIM card that is from a network other than the one your phone is locked to
3. When Incorrect SIM error comes up, type *#9998*3323#.
4. White screen will appear with an exit option. Press the right softkey.
5. From the menu that appears, select the Malloc Fail option. This will reboot the phone and the normal service screens will appear.
6. Type *0141# and then press the green call key. "Personalization" or "Personalized" will appear.
7. Turn off your phone and put the original SIM back in.
8. Turn on your phone. You will receive a prompt to enter a password.
9. Type 8 zeros (00000000)
10. Completed. You have now unlocked your phone.



Thank you for using fixya..

call the customer care from your friends phone who using the same network..say ur sim no. which is at the back of the sim and ak for puk code they will say it.put ur sim switch on ur mobile and enter the no.thats it over.

Hi,

PUK means "personal unlocking key" .

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

You need to call your phone service company, they can retrieve the puk code from a database
for free.

In your case you need to contact your SIM card phone 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 should not ask for the PUK anymore.

thank you,

well, you can choose to use a 'PIN code' or a 'Lock code' or 'Memory card lock'

1. PIN code actually locks up your SIM card, so anywhere you put your SIM card, the message on your SIM card will not be read by anybody without knowing your password. It'll ask you password each time you switch on your phone, but after switched on, it'll not be locked anymore, so anyone can read your phone after switched on.

2.while Lock code, locks your mobile phone like 'keypad lock', the different is, instead of just pressing , left softkey and * button, you need to put password on it (it lock after certain idle time - or you can choose to lock it anytime you want by pressing the on-off switch one time (don;t press too long) and choose the belowest which said lock phone ). this type of lock is commonly used.

3.Memory card lock, locks any application which access your memory card, such as images, text, songs, data that is stored on your memory card. but this type of lock, often bring troubles when the memory card get corrupted. so I suggest number 2 type of lock (lock code)



WARNING!!! all password should be remembered, as if you forgot those password, no body can help you unless technician.. see those articles which people post when they forget their password, so you know the risk and the consequences. But they're actually safe as long as you remember ^^

Good luck, all the best!!

I know this sounds dum but!!
does it say
insert sim
or
insert correct sim?
