Tells me to insert smartchip when its already inserted

Cut a small piece of cardboard or credit card plastic similar in shape to -- but just a bit smaller than -- the smart chip. Place the piece on top of the smart chip. Simultaneously slide both the smart chip and the piece of cardboard/plastic into the smart chip slot. Make certain you are inserting the smart chip with the proper end inserted first and with the contacts uncovered by the extra piece (On the LG Vu, the smart chip contacts will face down and the missing corner will be showing on the outside of the slot when the card is inserted properly.). If that doesn't do the trick -- see your cell phone provider and/or get a new phone.

SIM has probably gone bad ..att will replace it for free

Your smartchip is fried. You need to replace it and can get it from your carrier.

Turn your smart chip around. When inserted correct, you will be able to see the slanted corner of the chip.

DID U PUT IT IN BACKWARDS

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.

attempt to take the SIM card out and gently wipe it off (pay especial detail to the copper connectors on the under-side.) after that, give a gentle blow to the recieving area for the sim on the phone and place the sim back in the phone, power up, and hopefully this problem will be solved. this issue occurs often to myself and this seems to be a very simple solution.

I had the same problem but i fixed it. I'm not sure if this will work for you though. I took off the battery door and noticed that although my battery fit, it was somehow off by a few millimeters maybe. I took a tiny piece of paper, folded it and then fit it near the edge of the battery. This pushed the battery exactly where it should've been and then the phone could read the sim card again. I don't know how it got knocked outta wack but this seemed to help.

its a peice of **** thats what it is, it happened to me and wont fix!!!!

You have to insert the smart card all the way in on these phones. You can use a pen cap or something to push it all the way in there until it goes all the way in and click and stays there. Then it will not say " insert smart chip" anymore.
