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.
This appears to be cross posted. I'm guessing you hope someone can fix this phone but as it is not a smart phone and the manual does not show any sign of what you are asking for, my reading is that it's just like it was years ago (before smart phones.)
I do not have any memory left on my SIM card to add new contacts. How can I transfer present and new contacts to the phone memory.
