BB Does Not Connect With Dial-Up

All BlackBerry devices have the ability to act as a modem, which means you can connect your device to your computer and share the network connection from the BlackBerry. This process is known as tethering, and it can be configured as a dial-up service.


  1. Before you start troubleshooting the dial-up connection, ensure that your BlackBerry device is properly connected to your desktop or laptop computer. Use the USB cable that came with your Blackberry and make sure both ends are firmly plugged in to the appropriate ports.
  2. Configuration

  3. Open the "Network Connections" control panel on your computer and double-click on the "New Connection Wizard" link. Set up a new manual connection and select the "Connect using a dial-up modem" option. Choose "Modem - Standard Modem" as the connection type and enter "*99#" as the phone number. Press "Next" and "Finish" to save the configuration.
  4. Connection Testing

  5. Go back to the "Network Connections" window and double-click on the icon for your BlackBerry device. Enter your BlackBerry username and password and click "Dial" to initiate a new dial-up service connection

How Does a Dial Up Connection Work?
  1. A dial-up Internet connection is becoming more rare due to broadband and wireless Internet connections, but is still fairly common. A dial-up connection means that you use your telephone line to connect to an outside Internet Service Provider (ISP), which in turn connects you to the Internet. The parts of a dial-up connection include a modem, which transmits the signal from your computer to your phone line, and connects it to the modem at your ISP, as well as a telephone line.
  2. How It Connects to the Internet

  3. In order to connect to the Internet, the user first has to give the signal on the computer for it to connect. For instance, you usually double-click on the server icon (e.g., Internet Explorer or Mozilla), which initiates the dial-up process. You will hear a phone number being dialed, and then a series of clicks and beeps as the connection is being modulated to connect to your ISP's modem. Once it is done, it has acquired an Internet Protocol (IP) address from the ISP, which enables your computer to connect to the Internet network.
  4. Pros and Cons

  5. Dial-up connections are the most inexpensive type of Internet connection you can purchase, but this comes at a heavy price. Most of all, dial-up connections can be slow, both in connecting to the Internet and in loading Internet websites. This is because the phone line used in dial-up connects permits only a fairly limited stream of data from the ISP. For example, most dial-up connections allow about 56 kilobits per second while broadband permits as much as 512 kilobits per second, which makes a world of difference in terms of the speed of your Internet connection.

How Telephone Wiring Affects Dial-Up Internet

Dial-up Internet service allows computer users to go online over standard copper telephone lines. If the lines are of poor quality or have any form of interference, the dial-up connection may work poorly or not at all.


  1. Poor telephone wiring, according to the Internet reference website High Speed Internet Access Guide, can cause dial-up connections to fail to connect or terminate an existing connection. Less severe symptoms can include packet loss and numerous errors, and both of these conditions can cause the dial-up service to seem significantly slower than normal.
  2. Function

  3. In a dial-up connection, the user's computer modulates data into sound for transmission across the telephone line and demodulates incoming sound back into data. Each time the modem sends or receives data, it performs a quality check with the modem on the other end. If these checks fail, possibly because of poor line quality, the modem must resend the missing or corrupt data.
  4. Considerations

  5. Though poor quality telephone wiring can cause a number of dial-up issues, several other factors may lead to similar symptoms. According to the Internet reference website DSL Reports, issues like trouble on the telephone network, a faulty modem and even interference from analog telephones on the same line can also cause latency and outages.
