Tethering This option allows you to share your phone's mobile data connection via a direct USB connection between your phone and computer. A wireless version of this same functionality would be the Mobile AP feature. Note: You can not mount your phone's microSD card to your computer while using the USB tethering feature. If additional software or USB drivers are required, navigate to: http://www.samsung.com/us/support/ downloads. For more information, refer to "Tethering" on page 173. Mobile AP This feature allows you to turn your phone into a Wi-Fi hotspot. The feature works best when used in conjunction with HSPA+ (4G) data services (although 3G service can also be used). Important!: The Mobile AP service can not be active at the same time as Wi-Fi. Please close your Wi-Fi connection prior to launching the Mobile AP service. For more information, refer to "Mobile AP" on page 174. VPN settings The VPN settings menu allows you to set up and manage Virtual Private Networks (VPNs). Important!: Before you can use a VPN you must establish and configure one. Adding a VPN Before you add a VPN you must determine which VPN protocol to use: PPTP (Point-to-Point Tunneling Protocol), L2TP (Layer 2 Tunneling Protocol), L2TP/IPSec PSK (Pre-shared key based L2TP/IPSec), or L2TP/IPSec CRT (Certificate based L2TP/IPSec). 1. Press ➔ and then tap (Settings) ➔ Wireless and network ➔ VPN settings. 2. Tap Add VPN. 183
