Malicious or nuisance calls, SMS, and MMS messages 

If you receive malicious or nuisance calls, SMS, or MMS messages, you can submit a written complaint to your operator. The complaint must include details about the calling number, the date, and the time of receiving the calls, SMS, or MMS messages. Once the operator determines the necessary information about the sender, they will provide it to the competent police department for further action, and you will be notified in writing.

Wangiri calls (scam) 

If you receive calls from unknown numbers from abroad, it may be "Wangiri" calls that "ring only once" and remain recorded as missed calls, intending to make you return the calls, resulting in significantly higher costs. It could also be calls through which a third party seeks to obtain your personal data for fraudulent purposes or unlawful gains.
 
What can you do?

• If possible, block the caller's number on your device
• Report the calling number to your operator (date and time of calling).
• Report to HAKOM at the email address: nezeljeni.sms@hakom.hr  

If it is determined to be a "Wangiri" attack, the reported number is blocked for all users on the network.
 
Note that in the Republic of Croatia, incoming calls are not charged, regardless of the origin of the call.
