No, that is the first thing you should remove before sending it. When they go to put it on a plan, they would get a new sim card.

If the sim card has been deactivated you don't have anything to worry about, other than making certain all contacts have been deleted dim the sim card.

Might not be safe. Just ask your carrier to cancel the SIM card.
