Flightradar24 coverage is only available in areas where someone has installed an ADS-B receiver and shares data with the Flightradar24 network.
We are unable to provide coverage in areas where no ADS-B receivers are installed.
If you would like to contribute with feeding data as a host yourself to improve coverage, please see the following options:
