Only for KDE 4.4 and above


Using a regular mobile phone device like an ipod, Android or a regular phone with bluetooth capabilities for on-the-go broadband access is now possible with KDE4.4x and later versions, but not with earlier versions.


If you have bluedevil installed and running, right click the icon and exit the app. At the time of writing, bluedevil does not support dial-up connections, though it may do so in the future.

A prerequisite for most phones is that you have a data account enabled via your service provider to avoid excessive charges.

Requirements: install

  • kppp
  • Blueman


Start Blueman from K-Menu > Settings, Bluetooth Manager Left click on the new bluetooth icon in the system tray, then click on the binoculars icon to search for bluetooth devices, follow the prompts to connect to the phone and set up pairing and a trust relationship if you have not already done so, then close the window.

- Optional - Right click the Blueman icon in the tray and left click on Local Services. Under DUN Support, make sure NetworkManager is selected and close. There is no apply, it just happens in real-time.

Click (left) the Blueman tray icon again to open the regular Blueman interface, right click your phone, select Serial Ports > Dialup Service and a message will appear in the notification area "DUN connection on [nameofdevice] will now be available in NetworkManager" and in the blueman window, you'll see "Serial Port rfcomm0" under the Disconnect heading. If you see a message appear relating to a failure to connect to network manager, ignore it for now, there is a bug in Network Manager (KDE4.4 & 4.5) that causes it to ignore Bluetooth Serial Connections, so we will ignore that until it is fixed and use dial-up instead.

Open kppp and create a new account, call it something like 3G Mobile Tethering Phone number for most 3G networks is *99# or *777 for the older 2G networks. You may have to confirm this with your provider. Leave everything else as it is, and click OK to close the window. If any troubles later, try deselecting Store Password.

Click the Modem tab and create a new modem, give it a name like 3G Modem and change modem device to /dev/rfcomm0, leave everything else as it is and click on OK, This is an important step, do not try to proceed without clicking on OK first. Click on 3G Modem and click on Edit, then click on the Modem tab, then click on Query Modem. If all is well, you will see modem ready followed by all sorts of info about your phone. Close the window and click on OK, and OK again to get back to your kppp window.

Most providers do not require any user name and password, but some Unix systems usually will not operate without one, so to proceed, you may need to add one. In NZ, I use mobile@jamamobile for the user name and I leave the password field blank, but once again, check with your provider if you can not establish a connection without these fields filled in.
