## How to configure 3G/UMTS/… modem or AT capable phone?

As most modems support AT commands, this is pretty easy and you should use `at` `Connection`. For `Device` you should use device name as modem appears in your system, for example `/dev/ttyACM0` or `COM7:`.

Some modems expose more serial ports and you need to carefully choose the right one - for example only one of them can receive USSD notifications.

Note

On Linux, you might have to install usb-modeswitch to make your modem actually behave like a modem and not like a disk containing drivers for Windows.

## How to configure Symbian based phone?

The only support for Symbian phones is using applet installed to phone and Bluetooth connection. You should use `blues60` `Connection` and Bluetooth address of phone as `Device`. On older Symbian phones you will have to use gnapplet and `bluerfgnapbus` connection.

## How to configure Nokia phone?

If you have Series 40 (S40) phone, it should work using either Bluetooth or USB cable.

For Bluetooth connection, `bluephonet` `Connection` is always the right choice with Bluetooth address of phone as `Device`.

For USB cable choosing the right connection type is more tricky and depends on generation of your phone. Newest phones usually work with `dku2` and the older ones with `dlr3` as `Connection`.

Should you have old phone with serial cable (and USB to serial converter), `fbus` `Connection` is the right one.
