iOS: Connecting to the Internet

Summary

iPhone, iPad, and iPod touch connect to the Internet as necessary using Wi-Fi. If Wi-Fi is not available, iPhone and iPad (cellular models) can connect using your carrier's cellular network. This article provides an overview of these connections and additional resources.

Products Affected

iPad, iPhone, iPod touch

When you use an iOS app or feature that uses the Internet, your iPhone, iPad, or iPod attempts to connect to the Internet as follows:

  1. Your device connects to your current Wi-Fi network if available.
  2. If not available, your device attempts to connect to any nearby Wi-Fi networks you have previously used.
  3. If there are no previous Wi-Fi networks in range, a list of available Wi-Fi networks appears. You can tap to join a Wi-Fi network, and if necessary enter the password to join it.
    Note: Wi-Fi networks that require a password are indicated by a padlock icon next to them.
  4. If no Wi-Fi networks are available or if you choose not to join one, iPhone and iPad (cellular models) connect using an available cellular data network.

Wi-Fi

  • Wi-Fi is often faster than cellular data networks, but may not be available in many locations.
  • To locate nearby Wi-Fi networks, tap Settings > Wi-Fi. Tap a network to join it.
  • Depending on the Wi-Fi network, it may be necessary to enter a password.
  • When connected to a Wi-Fi network, the Wi-Fi icon in the status bar displays connection strength. The more bars you see, the stronger the connection.
  • Many Wi-Fi networks can be used free of charge, but some require a fee or subscription to use.

If you are experiencing difficulty joining a Wi-Fi network, see Troubleshooting Wi-Fi networks and connections for more information.

Note: iOS devices sold in China may use the term Wireless LAN (WLAN) instead of Wi-Fi. Not all China iPhone models support WLAN; see this article for more information.

Cellular data networks

  • Cellular data networks provide Internet connectivity using the cellular network. See Understanding cellular data networks for more information.
  • When your iPhone or iPad (cellular model) is connected a cellular data network, the status bar will display 4G, 3G, E, or °, depending on your iOS device and your carrier's network capabilities.
  • When traveling internationally, you may be able to use a cellular data network from another carrier. Roaming charges may apply.
  • You can adjust cellular network settings on iPhone in Settings > General > Cellular; on iPad the settings are located in Settings > Cellular Data.
  • Depending on the carrier, iPad users may sign up for monthly data plans from Settings > Cellular Data. For more information see How to set up a cellular data account.
