If your phone is a Cingular or AT&T branded Sony Ericsson Z525 and your Smart chip is from another cell company, you might have to get your phone unlocked. If it is from another AT&T phone, it should fit right in and power up. I know this might sound dumb, but always be sure the words "smartchip" are facing out with the little corner notch on the chip in the upper left when looking at the back of the phone. Hope this helps. -Mike

My lg phone says to add smart chip

The smartchip is the SIM. Without knowing which model you are working with it's hard to say for certain what the problem may be. On my older W580i, you have to slide the SIM all the way into the slot - until it actually clicks, locks into place and doesn't pop back out when you release it. The battery will not properly hold it in place.
For several other models I've seen people indicate that the SIM needs to be shimmed slightly - with the edge of a folded piece of paper, for example - to properly hold it in position against the contacts.

I got my lg View from a friend and when i put a sim card in it says Insert Smartchip

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.

When your sim card is already in your phone, but then suddenly it just starts saying insert smart chip...what does that mean.?

Insert SIM card means that the SIM is not seated correctly. It may not be locked into place and got jostled around when you plugged the phone into power. This message would not relate to a battery going dead, only to the device not recognizing the SIM card and that would only be if the SIM was not activated (which you know that it is active) or if it is not properly seated (locked down, etc.). Make sure that the SIM is properly seated (look at the manual to be sure) and then you should be okay. If this is not the case, and the SIM is properly seated, then the device is defective, broken or the unlocking caused faulty errors.

Says insert smart chip

smart chip means the SIM card.

try cleaning the metallic part of the SIM card with a cloth and the metal connectors on the phone with cotton bud etc.

Put it back and try again.

If not working grab another SIM card (working - friend's etc) to test.

If still not working, send to service centre.
If working for other SIM card then replace your own SIM card.

Says insert smart chip

It is possible to put the sim card in backwards.  My daughter did and when we turned it around I no longer got the "smart chip" error message.

My phone keeps saying insert smart chip

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.

How do you properly "garage" a car?

Putting it on bricks will help from rust forming on under side of car. Get some fuel stablizer in the fuel tank, some people say keep gas tank full so it dosn't rust. Idk...about that though.. I'ld also take out battery. Oh, after storage, make sure you change your oil! And I'ld keep looking for more info. I've never stored a car so I'm sure there maybe more tricks out there I don't know about.

On the top where the latch closes on the chip take it and put a curve in it to where it bows up. Mine did the same thing after i did that it worked fine.
