Using a BlackBerry Curve as a Modem/tethering


Here is a little tutorial explaining how to tether an AT&T Blackberry to a laptop. You do need the tethering plan, it costs extra. At the time of this writing (July 2009), the tethering plan also places a limit of 5GB to the monthly data transfer through the BlackBerry. If you exceed that limit, you will regret it quickly as the price of each MB above the 5GB limit is exhorbitant. Without the tethering plan, there is no such limit.

 

A BlackBerry device (with tethered modem capability) can be used as an external modem to connect a laptop computer to the Internet.

 

To set up a tethered modem, complete the following steps:

 

1.   Install BlackBerry Desktop Software version 4.1 or later

2.   Set up the Internet Access Point Name (APN) (one time only)

3.   Configure dial-up networking (one time only)

4.   Connect the BlackBerry device to BlackBerry Desktop Manager

5.   Connect to the Internet using dial-up networking

 

 

Step 1: Install BlackBerry Desktop Software version 4.1 or later on the laptop or personal computer.

 

When you install BlackBerry Desktop Software, the drivers that enable the BlackBerry device to communicate through the USB port and virtual COM port are installed. The Standard Modem, which is used by dial-up networking, is also installed.

 

Note: If you are upgrading your BlackBerry Desktop Software from version 4.0 to 4.1, the required Virtual COM Port and Standard Modem might be removed during the upgrade process. If this is the case, re-install the BlackBerry Desktop Software 4.1 or later and choose the Repair option to re-install these components.

 

Step 2: Set up Internet APN.

 

1.   Go to Start > Settings or Control Panel.

2.   Double-click Phone and Modem Options.

3.   In the Phone and Modem Options window, click the Modems tab.

4.   Select Standard Modem and click Properties.

5.   In the Standard Modem Properties window, Click the Advanced Tab.

6.   In the Extra initialization commands field, type the following: +cgdcont=1,"IP","<your Internet APN>" (remove the quote signs < and > when typing in your APN)

 

Example (for AT&T); +cgdcont=1,"IP","wap.cingular"

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

 

7.   Click OK.

8.   In the Phone and Modem Options window, click OK.

 

Here are the ATT/Cingular Settings:

 

APN: wap.cingular

user name for APN: WAP@CINGULARGPRS.COM

Password: CINGULAR1

This is how I found my settings on my BB Curve: go to Options -> Advanced Options -> TCP. The APN will say, for example, wap.cingular

 

Step 3: Configure Dial-up Networking

 

To configure dial-up networking, complete the procedure that corresponds to the operating system you are using.

 

Windows XP Operating System or Windows Vista

 

1.   Go to Start > Control Panel > Network Connections.

2.   Double-click New Connection Wizard. The New Connection Wizard opens.

3.   Click Next.

4.   Select the Connect to the Internet option. Click Next.

5.   Select Setup my connection manually. Click Next.

6.   Select Connect using a dial-up modem. Click Next.

7.   If the Select a Device screen appears, select the Modem - Standard Modem check box. Click Next.

8.   In the ISP Name field, type a name for your connection. I used “ATT Blackberry”. Click Next.

9.   In the Phone number field, type *99#. Click Next.

11. In the Modem Configuration window, clear the Enable hardware flow control check box and make sure none of the other check boxes are selected. Click OK.

12. In the Properties window, click OK.

 

Step 4: Connect the BlackBerry to the computer

 

1.      Open BlackBerry Desktop Manager software on the computer.

2.   Connect the BlackBerry device to the laptop computer and verify that BlackBerry Desktop Manager displays Connected. The device must be identified by BlackBerry Desktop Manager in order for the modem to establish a connection.

 

Important: BlackBerry Desktop Manager must be running for the tethered modem to function. Do not close the BlackBerry Desktop Manager software untill you are done with your session.

 

Step 5: Connect to the Internet using dial-up networking.

 

Note: While you are browsing the Internet on the computer usin the BackBerry as a modem, do not operate the BlackBerry Browser or any third-party applications using the Internet on the BlackBerry device. An active data session may interfere with the modem connection.

 

1.   Click Start > Control Panel > Network Connections > <name of your new connection>.

2.   Enter the user name and password provided by your service provider. (this should be saved there already)

3.   Click Dial.

 

You will now be connected to the AT&T Data service.

 

Each time you want to connect, you will have to repeat steps 4 and 5 in that order.
