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. ᮣ Press ➔ and then tap (Settings) ➔ Wireless and network ➔ Tethering and portable hotspot. For more information, refer to "Tethering" on page 187. 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 "Portable Wi-Fi Hotspot" on page 188.
