(Zedcor Wholly Owned/ Images)

You may use the Motorola RAZR cell phone as a “tethered” modem for a laptop or PC with Windows XP installed. As a backup or travel modem, the RAZR is quite sufficient to connect to the Internet from anywhere in the cell phone provider’s service area. Configuring the Motorola RAZR is simple; however, the access numbers, user IDs and passwords for cell providers differ by provider. The example provided below is for the Motorola RAZR on T-Mobile, Sprint and AT&T cellular services. (Consult with your cell phone provider for the correct configuration settings.)

Skill level:

Things you need

  • USB connector cable
  • Internet data plan with cell phone service provider
  • Laptop or PC
  • AT&T Communication Manager installed (if using AT&T)
  • Sprint CM Manager installed (if using Sprint)
