Is it ok to sell old iPhone 4 with SIM still in it?

I need to know this too so I'll just bump this.

 

Yes. The SIM doesn't store your data - just the carrier's. I sold my last 2 iPhones intact and whenever you get a new one, it already has a SIM and activates when you sync (and activate) it for the first time.

- Be sure to Erase All Content & Settings in general preferences, however...

 

You need a smaller paperclip. You could also cut the point off of a straight pin and use that. It should open easily with the right tool.

 

Well... I would make sure that you CAN eject the SIM before you sell it (especially on eBay). Don't wanna sell the other person a phone with a SIM tray that is faulty and won't eject.

But then... after that... I would send it with the old SIM in. Why?

I recently had a situation where the seller wanted to use it as an iPod and not have phone service. The old SIM card will allow iTunes to "activate" the phone and get into the OS. The SIM will not give them access to your account or be able to make calls. The only thing the person might be able to see is your phone number that USED to be tied to that SIM.
