DELTA Mobiel

The organisation operates under the aliases DELTA Mobiel and Caiway Mobiel, with its headquarters located in the Netherlands. It provides mobile telecommunications services, including voice, data and messaging, to customers in the Dutch market. These services are delivered as mobile virtual network offerings, leveraging underlying network infrastructure to supply connectivity. The brands are associated with the broader telecom providers Delta Fiber and Caiway, which also offer fixed‑line, internet and television solutions. By operating under two distinct brand names, the organisation addresses different customer segments while maintaining a unified operational base. Its core activity centres on enabling mobile communication for consumers and businesses across the country.

A notable distinguishing attribute is the data breach that occurred on 5 December 2022, which compromised personal information from the order systems of both DELTA Mobiel and Caiway Mobiel. The breach exposed names, addresses, email addresses, birth dates, phone numbers and bank account details, although passwords, credit card data and customer IDs remained secure. In response, the organisation disabled its order platforms, directly notified affected customers and advised them to watch for phishing attempts. It reported the incident to relevant regulatory authorities and engaged cybersecurity experts and law enforcement to investigate the breach. Updates were provided via dedicated informational pages, demonstrating a structured incident‑response approach despite existing security measures. No further structural details such as ownership or parent‑subsidiary relationships are explicitly stated in the available sources.
