1. The phone doesn’t appear in iTunes and won’t sync
- Check the phone battery. It may need recharging.
- Try a different USB port on your computer.
- Or, turn the phone off and turn it on again. Press and hold the Sleep/Wake button on top of iPhone for a few seconds until a red slider appears, and then slide the slider. Press and hold the Sleep/Wake button until the Apple logo appears.
- Or, restart your computer and reconnect iPhone to your computer.
- If none of these steps works, download and install (or reinstall) the latest version of iTunes from www.apple.com/itunes.
2. The phone won’t make or receive calls, send or receive text messages, or access email or the web
- Check the cell signal indicator in the status bar at the top of the screen. If there are no bars, or if it says “No service,” try moving to a different location. If indoors, try going outdoors or move closer to a window.
- Check to make sure you’re in an area with network coverage. Go to your carrier’s website to see network coverage areas.
- Make sure airplane mode isn’t on.
- You may need to turn airplane mode on, wait 15 seconds, then turn airplane mode off again.
- Make sure to include an area code for every phone number in your contacts list that you use to send or receive text messages.
- Turn the phone off and turn it on again.
- There may be an issue with your wireless service. In this case, call your carrier’s technical support.
- If none of these steps work, restore the iPhone software. See this document or see “Updating and Restoring iPhone Software” in the iPhone User’s Guide.
3. The phone won’t turn on, or the display freezes or doesn’t respond

- If that doesn’t work, turn iPhone off and turn it on again. Press and hold the Sleep/Wake button on top of iPhone for a few seconds until a red slider appears, and then slide the slider. Then press and hold the Sleep/Wake button until the Apple logo appears.
- If that doesn’t work, reset iPhone. Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears.
