if you take sim and battery out for about 15-20 minutes and boot up your phone, you should be fine, i talked to my stepdad, computer freak, he said it could be caused from me not ever shutting my phone off and it just getting hot

SOURCE: 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.

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.

My LG Vu today decided to say "Insert Smartchip" and I only have the "emergency" button available. I have tunred it around and around, and nothing works, any other ideas?


I had mine in upside down and that caused it to say insert smartchip.....could be a back sim card. If you have another phone test out the sim card in that phone or have your service provider help check the sim card

What do i do if invalid smartchip appears?


Your cellphone will only work with Cingular/AT&T smartchip. What kind of smart chip are you trying to use with LG CU400. I believe no other smartchip will do.

Insert Smartchip


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.
