Q: Lost sim ejection tool

You can use the end of a larger paper clip if you need to remove the SIM. Just unfold one end.

I don't know if Apple sells replacement SIM ejection tools on their own. You might try Fry's Electronics if you have one near you but even there, I dunno.

Search Amazon.com for "sim card ejector tool".

Wanna buy mine for $40? It's original Apple SIM card ejection tool. It's pretty. I've used it once so I'll give you 50% discount.
