Sorry... You can't

If you have backed your phone up or done regular file-saves of your address book data, you could restore it.

Contact your phone carrier and let them know that you accidentally deleted a very important text message.

Unfortunately this depends on how you stored the contacts and where you deleted them from. Contacts can be stored on the SIM card or directly in the phones memory. You can also move and copy the contacts both ways. If you go into your address book, and select the menu option (typically the top left button), you should see something about SIM management. This option will allow you to try and retrieve what contacts you may have on the SIM card. Hopefully all you did was delete the contacts on the phone itself, and you still of most of them on the SIM.

Hope this helps and good luck!

If it is asking network key then it is locked to the network. Use unlock code to unlock your Alcatel OT-510A(OT-510) from its AT&T network. Get the code from the site Unlock-Zone.com ,and unlock it using unlocking instructions which is given i the site itself.

Help me please, i have an at&t alcatel OT510 IMEI:013107001411782 and i need "network key"

go to home tap on edit. then there will be minus symbols next to the names of the books. tap the minus symbol next to that particular book. now hit the done button. the done button should be located where the edit button was. now go to the book store, search for your book and now you can retrieve it.

Please explain further.... What do you mean you want to delete double names in your address book. If its a DVD drive it can only read or writre data to a DVD. If the DVD is a RW then you have the ability to change the data ( rewrite, delete or possibly add), otherwise you can only use what you have placed on it.

How is a address book on a DVD drive?
