How to Convert From an iPhone to an iPod Without a SIM Card
If you use an iPhone you originally purchase from AT&T, you must have a SIM card inserted at all times in order to make phone calls and send text messages using your device. Additionally, your SIM card enables your carrier's cellular data network, permitting you to use "Always-On" Internet if you are within your monthly data allotment. Remove your iPhone's SIM card to use the device as you would an iPod Touch.
Things You'll Need
- Pin or needle
Cancel your cellular service account if you haven't already done so. Removing your SIM card from your iPhone prevents you from using your service on the device, but doesn't stop your carrier from continuing to bill you.
Remove the SIM card from your iPhone. Place the sharp end of a pin or needle gently into the hole on the top of your iPhone to pop out the tray and remove the SIM from it.
Sync your iPhone with iTunes whenever you want to update its music library, just as you would when you used the device with your mobile carrier. Tap the "iPod" icon -- followed by the name of a song, album or artist -- whenever you want to listen to music.
Make use of the Internet, email or any web-based application by using the iPhone's built in wireless adapter whenever you're in range of an available wireless network. Tap the "Settings" button, and then "Wi-Fi," tap the name of the network, enter its password if it has one and tap "Join."
