Network
Use the Network settings to configure a VPN (virtual private network) connection,

VPN
VPNs are often used within organizations to 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 or PPTP protocol and optionally use
either RSASecurID or Cryptocard for authentication. VPN works over both Wi-Fi and
cellular network connections.
Configure VPN
m Choose General > Network > VPN and tap Settings. 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.
Turn VPN on or off
Once you’ve entered VPN settings, a VPN switch appears at the top level of the
Settings list.
m Tap Settings and turn VPN on or off.
Wi-Fi

Data Roaming
Data Roaming turns on Internet and visual voicemail access over a cellular network

traveling, you can turn off Data Roaming to avoid potential roaming charges. By
default, Data Roaming is turned off.
m Choose General > Network and turn Data Roaming on or off.

iPhone can connect wirelessly to Bluetooth headsets and car kits for hands-free talking.
