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.

I have an lg shine from AT&T and yesterday it would not accept my sim card from AT&T. how do i fix it or is it fixable, i have seen several ppl complain about this very problem my sim card works in...


If your phone displays the 'Insert correct simcard' then your phone is currently locked to particular network. You need to unlock to use it with other network.
There can be many ways to Unlock your phone. As far as i know unlocking by codes is the simple and safe way. I will suggest the website Unlock-zone.com which is doing good service and they were recommended highly in the cell phone forums.
I used them to unlock my cell phone. contacted them and within 30 mins i had my unlock code and my phone was unlocked.
Hope this helps.

Phone not working.. Asking for smartchip


Sounds to me like your sim card is bad. Try wiping it off and putting it back, but you will most likely need to go get a new sim card.

I turn on my LG Shine cell phone and no matter


Turn off the phone. Take the battery and Sim Card out. Make sure there is no dust or dirt of where the Sim Card goes. Blow air (from your mouth) of where the Sim Card goes. Sometimes rubbing a soft pencil eraser on the Sim Card contact points can help. Then place the Sim Card back in the phone. Make sure it is in the right position; copper contacts facing downward. Put the battery back in your phone. Turn it on, and see if the smartchip rejected goes away.

If not you may need to contact your Phone Provider’s Tech Support to troubleshoot and confirm that you may need a PUK reset code to register or you may need a new Sim Card, as they do fail from time to time.

My micro SD card got stuck in my LG Vu phone


Yes there are 2 different places for the SIM card and memory card in the VU, but they are very close together. Try using a small pair of tweezers to gently grab both sides of the card and slowly pull it out.
