How to use the T-Mobile Blackberry Pearl phone as a modem.

Posted in Uncategorized by Greg Mackay on June 30, 2009

You can use your T-Mobile phone to connect to the internet via a laptop. The speeds are pretty slow but if all you need to do is check your email or do some light surfing it works fine.

All you need is a T-Mobile Blackberry Pearl 8100 and the data cable that came with it.

The steps below have only been tested on a Windows Vista laptop and a T-Mobile phone.

Step by step instructions:

1. First you need to have the BlackBerry Desktop Software 4.1 or later installed on your computer.

2. Set up an Internet APN.

  1. Start>Control Panel>Hardware and Sound>Phone and Modem Options.
  2. In the Phone and Modem Options window, click the Modems tab.
  3. Select Standard Modem and click Properties.
  4. Click on Change Settings.
  5. In the Standard Modem Properties window, click the Advanced tab.
  6. In the Extra initialization commands field, type the following: +cgdcont=1,"IP","wap.voicestream.com"
  7. Click OK.
  8. In the Phone and Modem Options window, click OK.

3. Now you need to set up a new dial up connection.

  1. Start>Control Panel>Network and Internet>Network and Sharing Center.
  2. Click on Set up a connection or network in the left column.
  3. Click on Set up a dial-up connection.
  4. Click next.
  5. Click Standard Modem.
  6. In the Dial-up phone number field put *99#
  7. In the User name and Password fields put you’re my T-mobile username and password. That is what worked for me. I’m not 100% sure on this step. You may need to experiment some.
  8. Click connect.

4. After creating the dial-up network connection, open BlackBerry Desktop Manager and select Connection Settings from the Options menu. Instead of selecting USB-PIN, select the COM port (COM3 for example). Check Enable USB-to-serial converter compatibility. Important: Do not click on Detect. Click OK instead. BlackBerry Desktop Manager shows disconnected. You should now be able to connect successfully

1. BlackBerry Desktop Manager must be running for the tethered modem to function.
2. Step 3 won’t make a connection until you also complete step 4. I guess you could reverse them if you want.
3. During this procedure, do not operate the BlackBerry® Browser or any third-party applications on the BlackBerry device. An active data session may interfere with the modem connection. Also, make sure an Ethernet connection is not active at the same time.
