My lg tu500 keeps saying insufficient memory even though there is nothing on the phnone, no contacts, no photos or messages, no walpapers or screensavers, have two ringtones only yet also will not allow me to take photos, yet another member has exact same phone without the problems....

when i connect any web my mobile message me insufficient memory.

go to seeting,, use clear memory card

it is may be due to the damage or corruption of your sim card u can contact to the service provider for the new sim card on same number they will help

you re inset it 

Check your sent items and outbox folder to see if the you have any multimedia messages stored using up space...

If not then the image you are trying to send could be too large to send and save... Even though you have it set on Memory Card memory, the phone still uses its internal memory for things like the actual sending if you dont have enough space on the handset, it will show the message above

go into phone settings - memory manager - handset common memory and tap clear all. This worked for me i took my memory card out just to be on the safe side

Yeah it's pretty common. If you don't have a memory card, then it's cause you have too many photos/songs etc on the phone taking up memory. If you do have one, make sure you have everything saved to it and then go into the settings and clear the phone memory.
That'll fix it.

You have to add your pictures to the phone memory first .And then you can able to add to your contact list.

I suggest reducing the size of the SD card to a 512mb and you should have no problem. There have been problems with the 1GB for these phones and I mhave 2 of these phones and they both have 512mb with no problem any larger and they keep giving error messages
