Blackberry Modem

Do with this what you will – if you don’t have an unlimited data plan, this is not for you.

The following is a conglomeration of data that has proven very handy. Posting it to share with my online friends. Mine has been working great on AT&T for several months. I generally get a 128K connection. It’s not the fastest but it’s a great utility. Most carriers have this feature available but require a fee. This does not.

4. Connect Your BlackBerry
Make sure your BlackBerry is connected by USB cable, and your BlackBerry Handheld
Manager is running (just launch BlackBerry Desktop to run it.) This is necessary for
using the BlackBerry as an external modem. You cannot use BlackBerry as a modem
unless you have BlackBerry Handheld Manager running in the background! Note: For a
Bluetooth modem connection on new Curve devices the BlackBerry Manager does not
have to run in the background for the connection to work. You need to simply pair
your laptop and the Curve.
5. Modem Driver Install
If you installed a recent version of BlackBerry Desktop that came with a new
Blackberry, it should include modem drivers and already be automatically installed. In
the event you need to manually install them, the modem drivers should be located in
this directory:
C:\program files\Common Files\Research In Motion\Modem Drivers
However, if you are having problems with these drivers, uninstall, delete all leftover
RIM files, and then reinstall the latest version of BlackBerry Desktop.
6. Verify The Modem Driver Is Functioning
Go to Control Panel -> Phone & Modem Options. In the Modems tab, you should see a
new Standard Modem on a new port (such as COM6 or COM11). Click Properties ->
Diagnostics -> Query Modem. You should see the following:Quote:
AT+GMM – BlackBerry IPmodem
ATI1 – Research In Motion / BlackBerry IPmodem
ATI2 – Research In Motion / BlackBerry IPmodem
ATI3 – Research In Motion / BlackBerry IPmodem
ATI4 – Research In Motion / BlackBerry IPmodem
ATI5 – Research In Motion / BlackBerry IPmodem
ATI6 – Research In Motion / BlackBerry IPmodem
ATI7 – Research In Motion / BlackBerry IPmodem
Note: This may look different on Nextel 7520, or Sprint/Verizon/Bell Mobility 7250.
This is normal. Just make sure there is a response at all, rather than no response.
Click Properties -> Advanced. Add only ONE of the following Extra initialization
commands with the appropriate carrier-specific APN Setting:
