What sort of services and traffic does the alert system apply to?

The alert system applies to mobile telephony and mobile Internet for which you receive an invoice afterwards (postpaid).

The system does not apply to:

  • mobile telephony and Internet through prepaid cards;
  • fixed telephony;
  • broadband Internet over a landline or cable.


For a number of services provided by means of premium numbers or SMS messages and data roaming services within the EU a specific alert system applies.

Operators can choose whether they include the costs of these services to determine whether the upper limits have been exceeded.  

If an operator decides not to include these costs in the general alert system, he has to inform you of this.
