When your phone is connected via Sprint Spark, the Sprint Spark icon appears in the status bar.
Note: The Sprint Spark network is self-discoverable, which means no additional steps are required
for your phone to connect to it.
Your 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, followed by “@sprintpcs.com.” (For example, the
third John Smith to sign up for Sprint data services might have [email protected] as his user
name.)
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.
