The centre may even be able to block spammers from sending their messages to your phone in the future too.
A children's charity reckons more than a quarter of all kids between 11 and 19 have been sent threatening texts.
One of the men behind the scheme, Nils Granath, says most mobile companies will be using the system soon.
Later the system may be updated to let parents get a copy of all the texts their children send too.
