The SIM card is available from the phone service providers. The SIM cards are linked to the phone service provider. These SIMs are purchased from the phone service provider, it can be a prepaid type or one that is a phone contract.

If you had locked your mobile then update the formware all saved passwords will be deleted

You do one thing. First copy all the messagesyou have in the memory in a place. Then randomly delete all from the old phone. I'm sorry Sir, but messages can't be copied into the sim memory. Sim memory can only hold contacts ( that also to a limited extent ).

IF U ARE USING THE SAME CARRIER AS BEFORE (ATT FOR EXAMPLE) IT WONT NEED UNLOCKED. IF U WERE GIVEN A NEW SIM CARD FROM UR CARRIER WHEN THE NEW PHONE WAS BOUGHT, THEN YOU WILL HAVE TO USE THE SIM CARD. THE CARRIER ATTACHES THE SIM CARD NUMBER TO UR ACCOUNT. YOUR OLD ONE CAN BE USED ONLY TO ACCESS YOUR CONTACTS, BUT NOT TO MAKE CALLS.YOU CAN HOWEVER PUT THE OLD SIM CARD IN UR NEW PHONE FOR THE SOLE PURPOSE OF TRANSFERRING UR CONTACTS, THEN REPLACE YOUR NEW SIM CARD INTO UR NEW PHONE
