how to Use your mobile phone as a wireless modem

Did you know you can use a mobile telephone as a wireless modem? If your phone and computer can connect over IrDA or Bluetooth, you're well on your way.
You can connect your Macintosh to the Internet using a GPRS (General Packet Radio Service) mobile telephone as a modem. To do so, you should first make sure that you can:
  • Connect to the Internet over GPRS using the WAP browser in your telephone
  • Connect your Macintosh to your mobile phone over IrDA or Bluetooth.

Once you can do these two things, you can set up your computer to use the telephone as a wireless modem to connect to the Internet.

Important: GPRS data services and Internet access are typically optional offerings. Ask your mobile phone operator about GPRS availability in your area, and what the subscription fees and service charges are.


Using your mobile phone as a wireless modem

Once you have made the appropriate network settings on your Mac, you can use your mobile phone as a wireless modem.
  1. Ask your mobile phone operator for the network settings necessary to use your GPRS mobile phone as a modem. In some cases, you'll use the same network settings that your phone uses. In others, you may need to get network settings specific for computers. Typically, these settings include:
    • GPRS dial-up number
    • User ID
    • Password
    • IP Address
    • DNS Address
    • other advanced settings such as authentication, data compression, header compression, and quality of service
  2. From the Apple menu, choose System Preferences.
  3. From the View menu, choose Network.
  4. Choose New Location from the Location pop-up menu.
  5. Type a name for the new location such as "Wireless Modem".
  6. Choose "Network Port Configurations" from the Show pop-up menu.
  7. Make sure the "USB Bluetooth Modem Adapter" is enabled. Deselect the ports or interfaces you aren't using in this location, such as "Built-in Ethernet", and "Internal Modem".
