According to the news agency BNS (The Baltic News Service) Latvians can support their own Eurovision Song Contest entry F.L.Y. by calling via Estonia.
Eurovision Song Contest rules do not allow to vote for the contestant which represent their own country. Devoted F.L.Y. fans living in Latvia can vote for Hello From Mars by placing calls to the number assigned to the Latvian act for voting in Estonia.
BNS will not disclose this number out of ethical considerations.
