More and more subscribers are pestered and bothered with malicious calls from persons that use prepaid cards from fixed and mobile operators. These calls cannot be back-traced to the caller because no caller identification is possible. More and more 'stalkers' are using this technique to remain undiscovered. Until now, there is no solution available. Prepaid cards are intended to keep the caller unknown to the service provider, however this should not be abused for malicious purposes.
