HOWTO: BlackBerry As Modem For Laptop (Tethering)

  1. Introduction
    Did you know that BlackBerry can now be used just like an external modem for a laptop computer, so that a laptop can have full Internet access? This is useful when you need to do certain things that a BlackBerry cannot yet do. Increasing numbers of success reports have caused me to post this message. (Note: Mark Rejhon has not himself yet successfully used a BlackBerry as a modem; I am aggregating information). Sometimes, it is still tricky to set up a BlackBerry as a modem for a laptop, but this feature is becoming more and more common in cellphones, and BlackBerry models are following suit.

    .
    IMPORTANT:
    Other Models Than Listed Above: There is no modem built in. However, you can use third-party modem software called Shark Modem at http://www.mobishark.com/
    .
  4. Supported Carriers
    Carrier AT&T: Success!
    Carrier Rogers: Success!
    Carrier Vodafone: Success!
    Carrier T-Mobile: Success!
    Carrier SwissCom: Success!
    Carrier Verizon: Sometimes Successful
    Carrier Cingular: Sometimes Successful
    Carrier Nextel/Telus: May need to use http://www.mobishark.com/</a>
    Carrier Sprint: May need to use http://www.mobishark.com/
    Carrier Bell Mobility: 7130e Confirmed, Must use http://www.mobishark.com/ otherwise
    Currently, Rogers, AT&T, T-Mobile, and Vodafone UK are reported to work. Sometimes and Cingular works, but is much harder to setup. No confirmations for other carriers yet.
    Important: If you are using a BES 4.0 server, your BES 4.0 server, you should not use the “Disable IPmodem” setting. BES hosting providers such as eOutlook/Mailstreet/BES4U/MyBlueberry must avoid setting the “Disable IPmodem” setting.
    .
  5. 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.
    .
  6. Modem Driver Install
    If you installed a recent version of BlackBerry Desktop that came with a 7100t, 7290, 7250, or 7520, 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.
    .
  7. 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:

    ATQ0V1E0 – OK
    AT+GMM – BlackBerry IPmodem
    AT+FCLASS=? COMMAND NOT SUPPORTED
    AT#CLS=? COMMAND NOT SUPPORTED
    AT+GCI? COMMAND NOT SUPPORTED
    AT+GCI=? COMMAND NOT SUPPORTED
    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.
    .

  8. IMPORTANT SPECIAL CONFIGURATION STEP
    Click Properties -> Advanced. Add only ONE of the following Extra initialization commands with the appropriate carrier-specific APN Setting:

    • For Vista users only: Under Control Panel>Phone and Modem>Properties on the General Tab, click “Change Settings”. After giving Administrator approval, click the Advanced tab. There, enter the appropriate APN settings for your carrier as noted below.
