Excuse me, this is Nokia 5233. How to back up the address book and text messages in the mobile phone to the computer hard disk? Thank you.

It's simple. Go to Nokia's official website. Or download a PC suite from other websites. After downloading and installing, connect the mobile phone and the computer with a data cable, select the PC suite as the link mode, then use the address book function in the PC suite to select all the mobile phones to be backed up, then click Export in the file in the upper left corner of the dialog box, and then select the location to save, such as disk or desktop, and you can export the address book on the mobile phone!
