Ofono Telephony functions

Plasma Mobile uses ofono to communicate with telephony hardware. Ofono allows to make calls, send and receive sms and use the mobile broadband network.


Phonesim will add a fake phone modem, that can be controlled via a Qt based user interface from which it will be possible to test various aspects of the phone UI: making calls, receiving, signal strength, send SMS and so on. It will not generate any real call, but only make the UI think a SIM is working and that a phone call is in progress.

The current stable release of phonesim is still based on Qt4, therefore we recommend compiling the Qt5 based git master branch. In some cases, you might be able to install ofono-phonesim from your distribution’s repository.

To set up ofono-phonesim for development:

  • Edit /etc/ofono/phonesim.conf, uncomment everything so that it looks like
  • Start ofonod as root

  • Start phonesim

    Please note that the binary may be called ofono-phonesim in some distributions.

    phonesim -p 12345 -gui /usr/share/phonesim/default.xml

    A bit surprisingly, at first nothing will happen. That is fine, since the UI will only be displayed once the virtual modem is activated.

  • From the oFono source directory, call ./test/enable-modem to bring the modem up, the control UI should come up

  • Call ./test/online-modem to activate the test phonesim modem

On an actual device

Ofono can be controlled (for development purposes), using scripts located in /usr/share/ofono/scripts/.
