Archived - Using an iPhone without a wireless service plan
If you upgrade your iPhone to a newer model, you can continue using your old iPhone without an active cellular service.
Follow these steps to use your 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.
Note: It may be necessary to repeat this process after updating or restoring the device.
