The Australian Communications and Media Authority (ACMA) revealed that mobile phone companies will be debarred from charging consumers for premium SMS messages against their will. Premium SMS services, a subscription based texts offers content like ringtones and games, delivering it directly to mobile phones and cost more than a standard SMS.

Charges for premium SMS range from 55 cents for a competition to more than $6 for items like ringtones and games.

From July 1, customers will possess the right to block all unnecessary premium text and multimedia messages from their mobile phones, meaning that consumers will no longer be able to receive, send or are charged for any premium SMS or MMS services to which they have subscribed.

"This will be a great option for parents who want to make sure their kids don't sign up for something without understanding the charges," ACMA Chairman Chris Chapman posted in a statement. In addition, he reveals that it is an essential change particularly for parents, as children often sign up to the services without getting information about their terms and conditions.
