Send a text to spend a penny

Finland's equivalent of the UK Highways Agency has started locking roadside toilets in isolated areas to prevent vandalism. However, customers can still use them, thanks to text messages. All you do is text the Finnish word for “open” to a special code and the door will unlock automatically. Mobile numbers will be stored for a short while, which will increase the possibility of tracing any vandals. The service is charged as a standard text message. [Source: Cellular-News.com]
