Data Connection Status and Indicators
Your phone displays the current status of your data connection through indicators at the top of the
screen. The following symbols are used:
Your phone is connected to the 4G network. When the symbol is animated, your phone is
transferring data (for example, when you are opening a Web page); when the symbol is not
animated, your phone is connected to the network but is not currently transferring data (for
example, when you are viewing a Web page that is completely open). In either state, you can
receive incoming calls.
Your phone is connected to the 3G Mobile Broadband Network (3G). When the symbol is animated,
your phone is transferring data (for example, when you are opening a Web page); when the symbol
is not animated, your phone is connected to the network but is not currently transferring data (for
example, when you are viewing a Web page that is completely open). In either state, you can
receive incoming calls.
If you do not see an indicator, your phone does not have a current data connection. To check your
current connection options, touch > > Settings > Mobile networks and ensure that
Data enabled is checked.
Note: If your phone is currently connected to Wi-Fi, you won't see 3G or 4G icons animated.
Virtual Private Networks (VPN)
From your phone, you can add, set up, and manage virtual private networks (VPNs) that allow you
to connect and access resources inside a secured local network, such as your corporate network.
Prepare Your Phone for VPN Connection
Depending on the type of VPN you are using at work, you may be required to enter your login
credentials or install security certificates before you can connect to your company’s local network.
You can get this information from your network administrator.
Before you can initiate a VPN connection, your phone must first establish a Wi-Fi or data
connection. For information about setting up and using these connections on your phone, see
Launch a Web Connection and Turn Wi-Fi On and Connect to a Wireless Network .
Set Up Secure Credential Storage
If your network administrator instructs you to download and install security certificates, you must
first set up the phone's secure credential storage.
