I looked at http://reviews.cnet.com/cell-phones/lg-a340-gray-at/4505-6454_7-35190170.html and a little more and this phone is a standard flip phone without such a feature. You may have to move to a bigger smart phone.
I have a LG A340 cell phone. It keeps saying Memory full for SMS and Contacts. I have just bought and installed a micro SD card. How do I get the contacts and the SMS messages to store in the Micro SD card instead of the phone memory
