Should I take my sim card out before I sell my iphone?

I just bought out my contract from my phone carrier and got the phone unlocked, and now I want to sell it. So should I take the sim card out when I sell it or leave it in?

DUH!

Take it out.
They'll only put a new one in it when they get it anyway.

Depends, do you want the person that gets your phone to have all of your information and contacts?

Of course you should take your sim card. You don't wanna give your contact info to the person who's buying your phone ^^"

Take it out. It can't be re-used, but probably has a lot of your phone contacts in it.

Yeah, unless you want the phone's new owner making calls on your bill. The sim card is your account; anything that a phone does when it's installed is YOUR responsibility. You do NOT want a stranger (or most of the time even a good friend) having access to it.

You should take it out, do not leave Sim card in your handset.

  • What Happens When You Take The Sim Card Out Of An Iphone 4s? If I Take The Sim Card Out Will I Still Be Able To Use My IPhone? What Features Will Work And What Features Won't? Will My Contacts/Notes/Texts Etc. Be Erased? Can I Still Get On The Internet If I Have Wi-Fi? Can I Still Use Maps On My IPhone?
  • Should I Take The Sim Card Out Of iPhone? I bought this iPhone about a year ago from someone off eBay and it already has an existing SIM card in it with no problems. I sold the iPhone 4s on eBay today and I thought I would just leave it in for the next person to use. I already cancelled my number and transferred it to a new SIM card so the other one should be blank now right?
  • Should I remove my sim card before or after I factory reset my my iphone 6s plus? Want to factory reset (I know how to) my unlocked iphone 6s plus for troubleshooting purposes and start from scratch as a new device or maybe I ll sell it if i change my mind. Anyways my question is do i take out the sim card before or after i factory reset. I don't care if factory resetting with the sim will cause any changes to it since i have backed up whatever i need including contacts.
  • If I take the sim card out would the owner be able to track the iphone? Okay so I found this iPhone 4/4s and I gave it to the people in the mall they gave it back to me because the owner didn't claim it in 2 months. The phone still has service and it's working correctly. What would happen if the owner started to track the iPhone and traced it back to me. Is there a way for them to trace it back to me? Even tho I took out the sim card?
