Article: HT3406 Using an iPhone without a wireless service plan
- Insert the SIM card from your new, activated iPhone or one that was previously used to activate the original iPhone.
- Connect the iPhone to iTunes on a computer connected to the Internet.
Once iTunes activates the device, you're free to use the iPhone as if it were an iPod touch.
Personal Unlocking Key (PUK)
If you enter the PIN incorrectly three times, you may need to enter a Personal Unlocking Key (PUK) to enable your SIM card again. Refer to the SIM card documentation or contact your carrier.
Note: Entering an incorrect PUK code too many times will result in the SIM becoming permanently locked. If this occurs, you will need to contact your carrier for a replacement SIM card.
The carrier is the only place you can get the PUK.
