There is some confusion in how-to setup a BlackBerry in tether mode to share internet with your laptop or PC so I would like to share my setup process.


Since you are already paying for a data plan why not take advantage of this data connection when you are away from home? Hotels and other facilities can charge you $15+ per day for Internet access.
BlackBerry and other hardware providers allow you to tether your smart phone as a modem to your laptop or computer.

Keep in mind that your tethered modem will not operate any faster than your data plan.
GPRS and EDGE will give you 2G speeds of approximately 56 – 114 kbit/s depending on signal strength; which will be similar to a dialup modem connection.
3G can provide up to 14.4 MBit/s download and 5.8 MBit/s upload.

RIM has provided instructions on how-to connect to the Internet using a GPRS, EDGE or UMTS smart phone as a tethered modem.
I had to make some modifications to these instructions to allow my smart phone to properly allow tethered access to the Internet. It is possible that each smart phone provider has slightly different setup so these instructions may not work for you.
These instructions work on the Rogers Canada wireless network, in particular, a BlackBerry Curve 8300.
These instructions should work with other data devices in tether mode.



Step 1) Download the Software
Do this first, Download the BlackBerry Desktop Software 4.1 or later which will install the USB and virtual com ports.
Otherwise your computer will not discover your mobile device.

The desktop software will allow you to copy files to your smart phone such as MP3, videos and load applications.


Step 2) Setup an APN (If Required)
Task 2 of the RIM instructions states you need to setup an Internet APN (Access Point Name), some data providers may not require an APN.
I found an APN is not needed as part of the Rogers wireless network. Do not setup an APN if you use Rogers or else your tethered modem will not work.

If you do not know your Internet APN or have connection troubles, contact your service provider.

To Set up Internet APN
From your PC:

  • Go to Start > Settings > Control Panel
  • Double-click Phone and Modem Options
  • In the Phone and Modem Options window, click the Modems tab
  • Select Standard Modem and click Properties
  • In the Standard Modem Properties window, Click the Advanced Tab
  • In the Extra initialization commands field, type the following: +cgdcont=1,”IP”,”your Internet APN”
    ie. +cgdcont=1, “IP”, “”
  • Click OK
  • In the Phone and Modem Options window, click OK


Step 3) Configure Dial-up Network

Windows Vista

  1. Click Start.
  2. Select Connect To.
  3. Click Setup a connection or network.
  4. Click Setup a dialup connection.
  5. In the Dial-up phone number field type *99#.
  6. Type the user name and password provided by your service provider.
  7. In the Connection Name field type BlackBerry (or any name you wish).
  8. Click Dialing Rules.
  9. Make sure the APN profile created in Step 2 has been selected (if required), and then click OK.
  10. Select Connect to establish an internet.

Windows XP operating system

  1. Click Start > Settings > 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 Set up 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. Click Next.
  9. In the Phone number field, type *99#. Click Next.
  10. Indicate which users will have access to the connection. Click Next.
  11. Type the user name and password provided by your service provider. Click Next.
  12. Click Finish.
  13. In the Connect window, click Properties.
  14. In the Properties window, verify that Modem - Standard Modem appears beneath the Connect using heading, and then click Configure.
  15. 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. In the Properties window, click OK.


Step 4) Connect to the Internet using Dial-up Network

  1. Power on your BlackBerry smart phone and connect it to the computer / laptop.
  2. Open BlackBerry Desktop Manager.
  3. Click Start > Settings > Network Connections > <name of your new connection>.
  4. Type the user name and password provided by your service provider.
  5. Click Dial.

The user name and password for the Rogers Wireless network is
user name: wapuser1
password: wap



There are all sorts of posts on various forums looking for setup instructions and APN values.
Be sure to contact you data phone provider for APN settings, it is very likely they will offer you very little to no support on this setup process (I have been told by family and friends).

Common problems I found are
- APN issues
- Desktop Manager must be running in order tether your device

Happy Tethering!

Thanks for the information. Do you know how I can share the internet connection above with other computers on my home network? I have a D-lnk router with wired and wireless connections.
