Dial-up networking (DUN) is the feature that converts your smartphone into a modem so that you can access the Internet from a laptop computer. If your computer is enabled with Bluetooth wireless technology, you can set up your smartphone as a wireless modem using the built-in Bluetooth technology. If your computer is not enabled with Bluetooth wireless technology, you need to purchase a wireless Bluetooth adapter accessory for your computer to use this feature.

First, create a partnership between your smartphone and your computer

If you've already set up a Trusted Device relationship with your computer, skip this section and go to the next section.

Creating a Trusted Device pairing lets your smartphone connect with your computer quickly. Then you can proceed to set up Dial Up Networking.

Make sure that your computer's Bluetooth setting is on and that your computer is ready to create a Bluetooth partnership. Check the documentation that came with your computer to find and change these settings.				On your smartphone, press Applications . Select Bluetooth.
Select Bluetooth: On if it is not already selected, and then select Setup Devices.				Select Trusted Devices.
Select Add Device. The discovery icon appears, indicating that the discovery process is active.				Select your computer from the Trusted Devices list, and then select OK.
Make up a passkey, and then select OK. Enter the same passkey on your computer when prompted.				Select Done, and then select Done again to return to the Bluetooth screen.

Next, set up the Internet connection using Bluetooth Dial-Up Networking

Now that you've created a Trusted Device partnership with your laptop computer, you can set up the Internet connection with your smartphone.

The steps for accessing the Internet on your computer may vary depending on your operating system and how Bluetooth wireless technology is set up on your computer. If you need additional info, check your computer's documentation for how to set up Bluetooth technology to access the Internet using a DUN connection.

You may need to use a virtual private network (VPN) to access corporate email. Check with your system administrator for more information.

Once you've done that, proceed with these steps.

On your PC, double-click My Computer on the Windows desktop. Double-click My Bluetooth Places. Your computer will scan for devices that are paired or in range.
Select your smartphone's Bluetooth name from the list of icons on the screen. It will not necessarily be called "Centro." It will have whatever name you gave it on the Bluetooth screen. By default, this is the same as its HotSync name. Then select Centro Dial-up networking.
A Bluetooth connection screen will appear. User Name: (leave blank) Password: (leave blank) Dial: #777 Important: If your mobile service provider is somebody else, contact them to learn which settings to use.
Click Dial. Once the connection is established, you should be able to browse the web or access your email on your computer using your smartphone as the modem. Look for a network connection icon in the taskbar at the bottom of your computer screen to verify that you are connected. If you see a message asking whether you want your computer to remember the dial text for this connection, we recommend that you say Yes. This avoids errors and the inconvenience of entering the dial text for every session.

When a DUN connection is active:

• You cannot use data services on your smartphone. For example, you cannot browse the Web, or send or receive email messages on your smartphone (however, you will be able to do these things on your laptop computer).
• Any scheduled automatic email retrievals do not take place on your smartphone.
• You can't connect your smartphone to other Bluetooth devices, such as sending a photo to another handheld, or receiving an application beamed to you via Bluetooth.
• You can, however, use other wireless features of your smartphone, such as making and receiving phone calls or sending and receiving text messages.

Be sure to read the next section about disconnecting from the Bluetooth DUN section.

Disconnect from the Bluetooth Dial Up Networking session

It is important to end a Bluetooth DUN session after you finish using it. Ending the DUN session lets you use the wireless features of your smartphone that require a data connection. It frees up the Bluetooth feature so that you can connect to other Bluetooth devices, and it optimizes battery life, too.

On your smartphone, press Applications . Select Bluetooth.

Select Bluetooth: Off.

This terminates the Bluetooth connection to your laptop computer.

If you like, you can turn Bluetooth back on by selecting On. This will allow you to perform other Bluetooth wireless operations with your smartphone.

To start another Bluetooth DUN connection, follow the steps above; it will not be automatically resumed when you turn Bluetooth back on.
