sim card was accidently placed into computer without carrier- card disappeared into computer- can card be extracted without ruining computer?
Can probably be removed by careful disassembly of components - just take your time. Or just replace the card reader unit completely.
Is this a computer or an iDevice? If it's a computer, then yes you can probably remove it by disassembly. If this is an iPhone or iPad, take it to an Apple store and have someone at the Genious Bar remove it. Do not attempt disassembly yourself.
