Hi,
The best thing is to format the phone.

To format nokia Nokia 3230 mobile please follow the below steps.

Please download the software called as 'Psiloc System Tools'.

You can download the system tool software from below website

Install it in your phone memory.DONOT install in your memory card because we will be removing the memory card.

Remove the memory card

Open the installed software.

Go to 'TOOLS'

You will find the option called as 'format phone',select it.

It will ask for confirmation, confirm it and it will format your phone.

It will restart while formatting and this process takes several minutes.

Once the mobile is started your mobile is formatted.

NOTE: Formatting will delete all your content from your phone memory.Take back up before formatting.

Thank you

Go to a mobile repairing shop.....ask them to unlock the card but if you don;t want to lose your data then copy all the data using your phone usb and then give them the card they will unlock that after unlocking it will be empty...now you can again copy your data to your card......

security code is a 4 digit or 5 digit (1234 or 12345)...but a much safer way is to take external memory card out of cell (do you have a adapter for the memory card to be read/placed into laptop/pc card reader slot and formatted) if so once placed in slot go to my computer see the drive the memory card is in right click and format......now place the card back in cell good as new.............

THIS WILL MAKE YOU LOOSE ALL FILES!!!
(even password)
Take the memorycard out of the phone and,
put it in a computer.Use filesystem FAT-32
to reformat your memorycard.
Now the card will work again!
No password, No files will be left after a
complete reformat
This is your solution! Please vote!

it is not about with phone. its about with your sim card. you know pin code. fi you input pin code, it wants you to input puk code for security

I was also getting bad format error on my LG kc550. Did a little research (read the instruction book) and if you want to properly format your card to work with the phone you must insert the card into the phone then connect the phone to your computer via the USB cable supplied. Go to "My Computer" and you should see that the phone and memory card are displayed as two separate external devices, when you try to access the memory card your computer should ask you to format it. Click Ok and a Format box will come up, click Ok again and your computer will format the memory card acordingly.

Unfortunatly this resulted in my losing 4gb of space on the card, i dont know wether its based on percentage or a fixed amount the phone needs but if thats the case you will need more than 4GB for your card to be formated for your phone
