Reset your usage statistics: Choose General > Usage, then tap Reset Statistics to clear the data and cumulative time statistics. The statistics for the amount of time iPhone has been unlocked and in standby mode aren’t reset.

Network

Use Network settings to configure a VPN (virtual private network) connection, access Wi-Fi settings, or turn Data Roaming on or off.

Turn 3G on or off (GSM models): Choose General > Network, then tap to turn 3G on or off.

Using 3G loads Internet data faster in some cases, but may decrease battery performance. If you’re making a lot of phone calls, you may want to turn 3G off to extend battery performance.

Turn Cellular Data on or off: Choose General > Network, then turn Cellular Data on or off.

If Cellular Data is turned off, you won’t be able to access the Internet unless you join a Wi-Fi network. By default, Cellular Data is turned on.

Turn Data Roaming on or off: Choose General > Network, then turn Data Roaming on or off.

Data Roaming turns on Internet and visual voicemail access over a cellular data network when you’re in an area not covered by your carrier’s network. For example, when you’re traveling, you can turn off Data Roaming to avoid potential roaming charges. By default, Data Roaming is turned off.

Turn Personal Hotspot on or off: Choose General > Network > Personal Hotspot, then turn Personal Hotspot on or off.

See “Personal Hotspot” on page 24.

Add a new VPN configuration: Choose General > Network > VPN > Add VPN Configuration.

VPNs used within organizations allow you to communicate private information securely over a non-private network. You may need to configure VPN, for example, to access your work email on iPhone.

iPhone can connect to VPNs that use the L2TP, PPTP, or Cisco IPSec protocols. VPN works over both Wi-Fi and cellular data network connections.

Ask your network administrator which settings to use. In most cases, if you’ve set up VPN on your computer, you can use the same VPN settings for iPhone.

Once you enter VPN settings, a VPN switch appears in the Settings menu that you can use to turn VPN on or off.

VPN may also be automatically set up by a configuration profile. See “Connecting to the Internet” on page 22.
