Your Data Services User Name
When you buy your phone and sign up for service, you’re automatically assigned a user name, which
is typically based on your name and a number.
When you use data services, your user name is submitted to identify you to the network. Your user
name is automatically programmed into your phone. You don’t have to enter it.
Update Your User Name
If you choose to change your user name and select a new one online, or make any changes to your
services, you must then update the profile on your phone.
1. From home, touch > Settings > System updates.
2. Touch Update Profile > OK.
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 Sprint Spark network. When the rays spin, data is being transferred;
when the Sprint Spark icon is gray, your phone is not currently transferring data.
Your phone is connected to the 3G Mobile Broadband Network (3G). When the 3G icon is animated,
your phone is transferring or receiving data; when the icon is gray, your phone is not currently
transferring data. 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 launch a
connection, see
Launch a Web Connection .
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.
