W100i

I have entered sim card but my Sony Ericsson w100i gives me a message "insert Sim Card". Is there any problem in phone and if phone is lock please help me how to unlock Sony Ericsson w100i?????

It is hardware problem,take the phone to some unlock/repair shop.

try with other sim card, some simcard could not be recognised by some SE phone. better way is to check with different operation card and if it still fails then it should be probably what satch1234 said.
