Blackberry As tethered Modem Using Vista


Blackberry As tethered Modem Using Vista

This guide is set up specifically for the Blackberry as a modem on Windows Vista. You will also need the Blackberry Desktop Software 4.1 or later.

At this point, Make sure you have already installed the Blackberry Desktop software version 4.1 or later and that the modem is correctly installed (this is part of the standard install for the desktop software).

To verify this, from the start menu, select control panel:

1. In the top right corner, type “phone modem” in the search box.

2. Select Phone and Modem Options


Select the Modems tab.

You should see “Standard Modem”. This is the Blackberry Modem.


Select “Standard Modem” from the modems tab and click the Properties button.

In the General tab, select Change Settings on the bottom (you must be an administrator to change these settings).


Click Continue on the User Account Control Security warning that follows.

Under the Advanced tab, you must be sure to enter the Extra Initialization Commands:

AT+CGDCONT=1,”IP”,”CELCOM3G”  (Celcom) 

AT+CGDCONT=1,”P”,”NET” or “UNET” (Maxis)


Click OK.

Next, from the start menu, select control panel:

1. In the top right corner, type “set up connection” in the search box.

2. Select Set up a dial-up connection


Next select Connect to the Internet.

Select Next.


If you are prompted to use a connection that you already have select No, create a new connection. Select Next.


In the “How Do you want to Connect?” box, select the last option: Dial-up.


Select Standard Modem as the modem to use.

Enter the following information in each box:

Dial-up phone number: *99#

User name:

1.[leave blank] for :Celcom

2.Maxis is :maxis

3.DiGi is:digi


1.[leave blank] for :Celcom

2.For Maxis is :wap

3.For Digi is :digi

(I renamed my connection name to: Blackberry Connection, you can pick your own creative title)

Select Connect.


Now you have to Turn Off IP Header Compression.

To do this, from the start menu, select control panel:

1. In the top right corner, type “connections” in the search box.

2. Select View Network Connections


Next, right click on the Dial-up connection that you have just created and select Properties.


Then go to the Networking tab.

Select Internet Protocol Version 4 (TCP/IPv4) (be sure to not uncheck the box) and then click Properties.


Then click the Advanced… button.


Within the PPP link section, uncheck Use IP header compression


Click OK to close all open dialog boxes.

Next go back at View Network Connections>click the blackberry connection and dial.

If prompted by the message “Internet connectivity test was unsuccessful”, If you still get an error after checking all settings you can try to resend your service book by clicking your Blackberry Options >> Advanced Options >> Host Routing Table. >> HIT MENU, then register (on your Blackberry device).

REMEMBER: The Blackberry Desktop software must be running while you have your Blackberry tethered via the USB cable to use the device as a modem.

    Pls do help, thanks.
