Tutorial : How to Send DTMF request from Nokia N900


Hi folks as we know Nokia N900 does not support sending DTMF request to the operator for credit check and other details.

Finally there is a way to do so with a click of a widget . The widget used to send DTMF request is called the USSD Widget. It is developed by Guseynov Alexey , Martin Grimme.

The widget has two ways of sending the DTMF requests one is by typing the DTMF in codes in USSD dial Pad.

And the other one is USSD Widget

So its now possible to see the DTMF response in the homescreen. This widget support automatic widget checking and many other customizations like font color, widget background colour etc..

The USSD widget need runtime components like

  • python-hildondesktop
  • hildon-desktop-python-loader
  • pexpect
  • ussd-common

And the USSD components like

  • Ussd-pad
  • Ussd Widget

You can Download the package with all components here.

Then transfer the contents of zip file to root of N900 i.e N900/

Then goto X-Terminal and Type

sudo gainroot

then

type cd MyDocs

place all the contents of downloaded zip file to root of N900 i.e N900/

then type

dpkg -i filename.deb

example:
