Last Updated: May 16, 2014

Answers to some of your questions about Wi-Fi

  • Does my Samsung Galaxy S III® battery last longer if I use a Wi-Fi connection?

    The Samsung Galaxy S III uses less battery power with a Wi-Fi signal than the Sprint networks.

    Note: Battery life depends on network conditions, your actual usage, and a number of other situations according to Sprint internal testing.

  • How can I be sure that my Wi-Fi connection is secure?

    Be sure you use Wi-Fi networks that require password protection.

    Open or unsecured Wi-Fi networks offer no data security.

    Your Samsung Galaxy S III captures the password in the initial setup and remembers it for the next time.

    Without a password, your information is not private unless you're also running software that encrypts data.

  • Do I have to re-enter my Wi-Fi provider information on my Samsung Galaxy S III each time I get to a spot where it's available?

    Your Samsung Galaxy S III can remember an unlimited number of available Wi-Fi networks. It's easy to add new Wi-Fi networks. The new network is ready to launch when your Samsung Galaxy S III is in range.

  • How do Wi-Fi and Sprint 4G LTE or 3G signals interact?

    Your Samsung Galaxy S III uses Wi-Fi first when both Wi-Fi and Sprint 4G or 3G are enabled. Your phone searches for a Sprint 4G or 3G signal when you travel outside of Wi-Fi range.

  • What happens when I leave my Wi-Fi network?

    When you leave a Wi-Fi network, the data session pauses and automatically reconnects to the Sprint 4G or 3G network.
