      please check that your SIM card is inserted properly and that you are in an area where you are able to have reception.
If you are inside a building, try going near a window.

Why is the Radio not working?

Please note that a 3.5mm headphone jack must be plugged in order for the radio application to work. The headphone jack will act as an antenna for the radio.

  • No headset: You must have a headset plugged in for the radio to work. If you have it plugged in, please double check that it is properly inserted and secure.
  • No signal: You may not have radio signals around you, therefore the radio will not be playing.
  • Wrong radio station: You may be on the wrong radio station channel, please double check the radio station you are on.

You can also try by going to the home screen and open the application switcher to close the radio application.
If that does not help, try rebooting your device.
