Ringtone websites which have been ripping people off have been forced to clean up their acts.
Hundreds of sites were checked out after lots of people complained they were misleading people about how much the things they sold actually cost.
More than half the sites investigated were aimed at children.
Over 300 sites were investigated, which lead to 54 of them being closed and 159 being forced to show correct information.
The biggest problems were prices not being labelled properly, and adverts suggesting that ringtones were free.
The issue was investigated by the European Union, as there were complaints about dodgy sites all over Europe.
They decided prices had to be clearly labelled, and that it should be easier for people to unsubscribe from mobile services.
