Samsung cell phones do more than just make phone calls. They can also store phone contact information, display calendars and run programs called "apps." To transfer data from a computer to a Samsung cell phone that uses the T-Mobile wireless service, use a USB data cable. You can get a USB data cable from an electronics store and sync the Samsung cell phone using the syncing program that comes with the cell phone.
Eject the DVD drive's disc tray. Place the installation disc that comes with the Samsung cell phone onto the tray and close the tray. If a laptop is being used instead of a desktop computer, insert the disc, label side up, into the loading slot at the front or on the side of the laptop.
Click through the customer agreement screens when the installer program appears on the screen. Enter any required information, as dictated by the Samsung cell phone, such as its model number or service provider, and personal information, such as your full name and home address.
Continue to follow the prompts until the installer program tells you it is finished. Quit the program. Reboot the computer.
Line up the plug of the USB data cable that matches the USB slot on the bottom of the Samsung cell phone. Insert the plug into the Samsung's USB slot.
Insert the other end of the USB data cable into an open USB slot on the computer.
Launch the Samsung cell phone's syncing program by selecting it from the "Start," "All Applications" menu.
Click on the "Sync" tab at the top of the program's main window. Choose which file you want to sync with the phone from the tabs that are at the top of the window (for example, the calendar or an application or a video or music).
Click the "Start Sync" button at the bottom of the window to transfer your choices from the computer's hard drive through the USB data cable to the Samsung phone.
Quit the program when the syncing has been completed. Remove the USB data cable from the Samsung cell phone and from the computer's USB slot.
