How to remove sim card, can't find the tray on the iPhone

On the right side on a GSM iPhone.

As was said, it is on the right side, and you should see a tiny hole to pop the sim tray out. Use a small paper clip.

Sure you have a GSM iPhone?

If you have a CDMA phone, it has not SIM card tray.

There is a sim card in a CDMA iPhone as well. My Verizon iPhone has a sim card tray.

You have a 4S. The SIM is only used for international roaming.

Correct but I was just pointing out that it does have the tray when Meg posted above stating that it does not.

Not sure if the Sprint iPhone has one since I don't have one.

The OP has a 4, not a 4S. The CDMA iPhone 4 does not have a SIM tray.

I guess I missed that. 😟 Pays to read....

The CDMA 4 does not have a SIM tray. The CDMA 4S does.
