Bluetooth cell phone connecting to a computer

Q: How do I know if my cell phone can connect to my computer with Bluetooth to do things like dial-up networking, transferring the phone book, or other tasks?

A: Not all devices that have Bluetooth in them are created equal. Bluetooth uses profiles to figure out exactly what the device can do. You can read more about what types of profiles exist over at or at

Most cell phones have a Hands-Free Profile (HFP) and a Headset Profile (HSP). These two profiles allow the cell phone to connect to either a car stereo system or a Bluetooth headset for hands free talking. This is where cell phones start to differ.

If you want to find out if your cell phone will connect with your computer the first thing you have to do is figure out exactly what you want the cell phone to do when it is connected. Do you want it to do dial-up networking (DUN)? Do you want it to sync the address book and contents, which is called Synchronization Profile (SYNC)? Do you want it to transfer files, which is called File Transfer Protocol (FTP) or did you want it to do something else?

There are many profiles out there so the key is to review all the profiles that exist and figure out exactly what you want to do. Then you will have to make sure that your cell phone and your computer support the profile.
