I just stuck my sim card in the slot but I think it's not on correctly and I can't get it out. I'm not very good with hardware issues.
First thing, be calm... and then try using a small flathead screwdriver to slide it out. Be gentle with it because you might damage it. If it's really stuck, take it to Verizon and have them try and remove it.
Once your card is in, you are not supposed to be able to just pull it back out. You have to push it in (and if the card is in correctly, it will depress a few mm) and then release... the card will then stick out just a bit more than when it was inserted. You can now pull your card out. I personally would not get a screw driver anywhere near that port. If it is clearly not fully inserted (ie, it is sticking out), and you have good access to the end of the card, you could try using a flat end pair of small tweezers to pull the card out.
I know what he did. It's in upside down. I actually did the same thing to a customer this morning. duh.
Go ahead and use tweezers/small needlenose pliers and pull it out.
You're not gonna hurt it.
Remember, the Sim Contacts face upward.
