The only thing that you must have is a SIM eject tool or simply a straightened paper clip or any pin-like object hard enough to push-open the SIM tray. BTW, this SIM eject tool came with the box when you bought your iPhone.


Here are the steps:

First, refer to the image below to locate the SIM card tray. To pull it out, you need to insert the SIM eject tool (or the paper clip) on the tiny hole on the top of the iPhone 3G or on the right-side of the iPhone 4. Push until the tray pops out.

NOTE: The tiny hole found on the top of the iPhone 4 is not for the SIM card tray, it is a microprhone. Please do not insert any thing in there.


Once the tray pops out, pull it out completely and replace the SIM with any SIM you want.


When you're putting it back make sure that the SIM carrier logo is facing the front of the iPhone. Don't force it if it get stuck, just pull it out again, and gently put it back.
