You may come across a situation where you need Internet access on your laptop and all you have is your BlackBerry device with mobile network coverage on it. Use your BlackBerry as a tethered modem and get the internet on your laptop. I have seen many users rely on BlackBerry as a Modem on a regular basis where their portable data card does not seems to work well.

I am going to post series of tutorial on using BlackBerry as a Tethered Modem. For using GSM BlackBerry as a Tethered Modem on Windows XP/Vista using USB cable continue following this post.

    Note: Before you set up your BlackBerry as a tethered modem on your PC/ laptop, check with your wireless service provider about the charges involved. Internet through your BlackBerry as a modem will cause very heavy amount of data transfer through your BlackBerry.

To make it easy I will divide this tutorial in following four steps.

Step –1: Install BlackBerry Desktop Manager and get required information from your wireless carrier

Visit this link to download and install BlackBerry Desktop Manager. If you already have the latest Desktop Manager installed then go to step 2. Make sure that your BlackBerry is NOT connected to the computer While you are installing Desktop Manager, because when you install BlackBerry Desktop Manager software, the drivers that allow the BlackBerry smartphone to communicate through the Universal Serial Bus (USB) port and virtual communications port are installed along with standard modem, which is used by dial-up networking.

You will need following information from your wireless carrier

There may not be set username and password for your carrier, in that case leave it blank.
For T-Mobile: APN=, Username: [blank] , Password: [blank]
For Rogers, Username=wapuser1, Password=wap
If you know above information about your carrier  then kindly leave it in the comments for other readers. Check out this link also. It may work for you.

Step-2: Set up the APN [Same instructions for Win XP and Vista].

    If you do not know your APN, or if you do not have an APN, contact your service provider.
