Uploading MP3 files to your Motorola RAZR allows you to use your cellular phone as an MP3 player. While many RAZR owners search for techniques to transfer files to a cell phone, "Motorola Phone Tools" synchronizes your computer with your phone and allows you to transfer photographs, songs and ringtones. This application is included with a number of cellular phone plans. If it is not included in your plan, you'll need to purchase it from the Motorola website.
Obtain a copy of "Motorola Phone Tools" if you don't already have this program. You can visit the Motorola Store website to purchase a copy (see Resources). As of February 2011, the latest version of this application is priced at $49.99. Install the program using the default settings.
Connect your Motorola RAZR to your computer using a USB cable or a Bluetooth connection. If you are using a Bluetooth connection, you must synchronize your computer and RAZR by searching for devices in the phone's Bluetooth menu.
Open "Motorola Phone Tools" (if it does not open automatically) and select your RAZR model. Allow the application to synchronize with your phone.
Click the "Audio Files" link on the program's main menu. You can find this under the "Transfer Files" section.
Navigate to the location containing the MP3 you wish to upload to your Motorola RAZR. Generally, MP3 files are located in the "Music" folder, under "Documents" on your computer. If you'd like to select more than one MP3, hold down the "Ctrl" key while clicking on each file.
Select the destination for the MP3 file(s) by choosing the folder under "Mobile Phone."
Click "Transfer to Phone" in the middle of the screen. Allow a few seconds for the MP3 to transfer to your RAZR. Disconnect the phone from your computer to access the new files.
