How to use your cell phone as a modem

Did you know you can use your cell phone as a modem for your laptop to access the Internet anywhere you have a cellular signal? If you are like me, you carry your notebook almost everywhere with you and it would be convenient to be able to connect to the Internet wherever you are--using your phone and the Bluetooth connection between your phone and laptop. I use this handy feature to tap into the data plan I have for my Blackberry and thought I'd share with you. 

Before I continue, the instructions below assume the following prerequisites have been met:
  • you have a RIM Blackberry Curve 8900 or Blackberry Curve 8520 with a data plan (my wireless service provider is T-Mobile and an unlimited data plan is probably best unless you don't surf much or would rather risk paying over-usage charges)
  • an established connection to your laptop via Bluetooth (for which the instructions below are applicable) or USB (although using a cable might limit your mobility). 
  • Windows XP with administrative rights
Now, shall we get started?

Setting up the modem
1. Click the Start menu, select Control Panel, then double click Bluetooth Devices. Select your handset from the list, then click Properties. Click the Services tab and ensure that Dial-up networking (DUN) is checked (if not, check the box). Click OK until you are back at the Control Panel.
2. From the Control Panel window, double click Phone and Modem Options. Click the Modems tab. Click to select Standard Modem over Bluethooth link (COM5), then click Properties. Click the Advanced tab. Type at+cgdcont=1,"IP","wap.voicestream.com" in the Extra initialization commands field. Click OK until you are back at the Control Panel.


Setting up the connection
3. In the Control Panel window, double click Network Connections. Under Network Tasks, click Create a new connection. When the New Connection Wizard window appears, click Next
  • Click to select Connect to the Internet, then click Next
  • Click to select Set up my connection manually, then click Next
  • Click to select Connect using a dial-up modem, then click Next
  • Click to select Standard Modem over Bluetooth link (ensure no other modems are checked) then click Next
  • In the ISP Name field, type T-Mobile Data, then click Next
  • In the Phone number field, type *99#, then click Next. Leave the Username and Password fields blank. I unchecked the available options including Make this the default Internet connection, click Next, then Finish
  • If you plan to use this connection often, you can check Add a shortcut to this connection to my desktop.


Making your connection
There are several ways to establish connection to T-Mobile Data.
  1. Use the shortcut on your desktop by double clicking on the icon, then click Dial.
  2. From the Network Connections window, right click on the T-Mobile Data icon under Dial-up, and select Connect from the popup submenu.
  3. Click Start, Connect to, T-Mobile Data, then Dial.
(Hint: To hide the Username and Password fields, click Properties, Options tab, and uncheck Prompt for name and password, certificate, etc. Other settings are available on the tabs found in this area.)
That's it! Now you can connect and browse the Internet on your laptop using T-Mobile Data on-the-go.
