Press Release
modulus S.A. announces that, within the framework of measures against fraudulent telephone calls using the “Caller ID Spoofing” or “CLI Spoofing” method (i.e. falsification of the caller’s number), and in implementation of the EETT Decision No. 1175/3/2025 (Government Gazette 6889/B/19.12.2025) titled “Amendment to EETT Decision No. 938/2/2020 regarding the provision of Calling Line Identification services”, it will apply mandatory blocking through its network, effective from 19.05.2026, to incoming calls originating from foreign networks when the displayed calling number is a Greek geographic number, namely a number beginning with +302.
The exceptions provided under paragraphs 4 and 5 of Article 1 of the above decision shall apply.
In practice, this means that the following cases are excluded:
- When the called number belongs to a foreign network subscriber roaming in Greece, incoming calls will continue to be routed normally.
- When a call originates from a call forwarding service, the call will be routed with the caller ID withheld. In other words, the call will be completed normally but without displaying the caller’s number. We recommend that subscribers receiving forwarded calls from abroad verify that anonymous call rejection services are not enabled, to avoid automatic rejection of such calls.
