The Connections Optimizer works by searching for available "remembered" Wi-Fi networks. If you do not
leave your Wi-Fi antenna on all the time, you will only notice the Connections Optimizer operating at
certain times of the day in a small number of locations on the network. Your Wi-Fi antenna will conserve
battery by scanning for connections periodically (not continuously), and if no connection is achieved, the
antennas will be turned off. You may also manually turn the antennas off during the scan period.
To facilitate quality assurance and enable feature enhancements, information is collected about your
battery levels, Wi-Fi and network connections and usage. No personal information is collected.
1. Press
networks > Connections optimizer.
2. Touch the check box to enable Connections optimizer.
Data Services General Information (3G and 4G
Networks)
With wireless service, you are ready to start enjoying the advantages of data services. The following
topics will help you learn the basics of using your data services, including managing your user name,
launching a data connection, and navigating the Web with your phone.
Important! Certain data services requests may require additional time to process. While your phone is
loading the requested service, the touchscreen keyboard may appear unresponsive when in fact it is
functioning properly. Allow the phone some time to process your data usage request.

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 your 10-digit wireless 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.
