Question about LG Vu CU920 Cellular Phone

LG phone flashing "Please insert Smartchip" when it is already in

I have an LG CU 720 Silver; it was working fine until last night when it switched to "Please insert Smartchip" screen while I was making a call. 
Now, it only works if I turn it off and on again. And then it only works for short periods of time.
When it works, I have access to all my messages, addresses, etc... so the chip seems to working just fine.
Any ideas?

I was told sometimes you have to wiggle it around sometimes, i was having the same problem this morning, i just wiggled it some without taking out the battery and it worked for me, if that doesnt work, maybe try taking out the battery and wiggling it some more. Hope this helps.

Insert smartchip


You are placing the smart chip on top of the smart chip holder. It's a little metal square where the smart chip should go. Lift up the metal square and place the smart chip underneath. I had to go to my local AT&T dealer to figure this out.

Tells me to insert smartchip when its already inserted


It did that for me too. But when I pushed it down gently and inserted it in, it worked for me.
