4G Services

4G is a service that must be included in your service plan and also available within your area. 4G
coverage is currently available in only certain markets. For more details on 4G availability go to:
sprint.com/4G and click the See the coverage map link.
Note: If 4G service is not included in your service plan, the 4G icon will not appear in the
Notifications area.
4G is up to 10x faster than 3G (based on download speed comparison of 3G's ~ 600 kbps vs. 4G's ~
6 Mbps). (Actual speeds may vary.)
Not all services are available on 4G and coverage may default to 3G/separate network where 4G is
not available.
Important! 4G service must be added to your account before attempting a connection to the 4G
network.
Depending on which icons appear within the Notifications area, your services and features will
change. The following table indicates what functions and features are available when combinations

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 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.
To connect to a VPN, you must have Mobile data enabled, or your phone must be connected to a
Wi-Fi network. For information about setting up and using these connections on your phone, see
Data Usage and Turn Wi-Fi On and Connect to a Wireless Network.
Set a Screen Lock
Before setting up a VPN, you must set a screen lock to prevent access to your phone by
unauthorized users. Pattern, PIN, or password screen locks provide sufficient security to set up
